iOS 11 disable password autofill accessory view option?

As of now I would like to opt out of the new option iOS 11 gives, that is to suggest passwords in the app. When I run the app on iOS 11 I get the autofill option on top of the keyboard and my username and password textfield don't even show up.

So, my question is, how can I disable the new password autofill feature all together so the key on the keyboard is not shown at all and the overall behavior is the same as pre iOS 11?

iOS 11 & 12 & 13 - Swift 4.2 & 5 (Updated):

        if #available(iOS 12, *) {
            // iOS 12 & 13: Not the best solution, but it works.
            passwordTextField.textContentType = .oneTimeCode
        } else {
            // iOS 11: Disables the autofill accessory view. 
            // For more information see the explanation below.
            emailTextField.textContentType = .init(rawValue: "")
            passwordTextField.textContentType = .init(rawValue: "")
        }

iOS 11 explanation:

Make sure you setup all of your UITextField objects like this.

If you have for example an UITextField object where the user must enter his email address and another one where the user must enter his password assign UITextContentType("") to both of their textContentType property. Otherwise it will not work and the autoFill accessory view will still be shown.


iOS 12 seems to recognise password textFields also by isSecureTextEntry property and not just by textContentType property, so making this accessory view disappear is not really possible unless you both set textContentType to nothing, and remove the secureEntry feature (and cause a security flaw in your app) which then prevents iOS 12 to recognise the textField as a password textField and show this annoying accessory view.

In my case the accessory caused a bug which made my app unresponsive when tapped (Which also got my app rejected in app review process). So I had to remove this feature. I didn't want to give on up this security feature so I had to solve things by my self.

The idea is to remove the secureEntry feature but add it by yourself manually. It did worked:


It can be done like that:

Swift 4 way:

First, as answered here, set textContentType to nothing:

if #available(iOS 10.0, *) {
    passwordText.textContentType = UITextContentType("")
    emailText.textContentType = UITextContentType("")
}

Than, declare a String variable which will later contain our textField real content:

var passwordValue = ""

Add a target to the passwordTextField, which will be called each time the textField content changes:

passwordText.addTarget(self, action: #selector(textFieldDidChange(_:)), for: .editingChanged)

Now That's what will do the magic, declare the function that will handle the text replacements:

@objc func textFieldDidChange(_ textField: UITextField) {
    if textField.text!.count > 1 {
        // User did copy & paste
        if passwordValue.count == 0 { // Pasted into an empty textField
            passwordValue = String(textField.text!)
        } else { // Pasted to a non empty textField
            passwordValue += textField.text!.substring(from: passwordValue.count)
        }
    } else {
        // User did input by keypad
        if textField.text!.count > passwordValue.count { // Added chars
            passwordValue += String(textField.text!.last!)
        } else if textField.text!.count < passwordValue.count { // Removed chars
            passwordValue = String(passwordValue.dropLast())
        }
    }
    self.passwordText.text = String(repeating: "•", count: self.passwordText.text!.count)
}

Finally, Set textField's autocorrectionType to .no to remove predictive text:

passwordText.autocorrectionType = .no

That's it, use passwordValue to perform your login.

Hope it'll help someone.

UPDATE

It catches pasted values also, forgot to add it before.


The feature can be disabled by specifying a content type that is neither username nor password. For example, if the user should enter an email address, you could use

usernameTextField?.textContentType = .emailAddress

You can add extension for UITextContentType like this

extension UITextContentType {
    public static let unspecified = UITextContentType("unspecified")
}

after that, you can use it

if #available(iOS 10.0, *) {
    passwordField.textContentType = .unspecified
}

A very simple approach in ios11 worked for me. Suppose your iboutlets are usernametextfield and passwordtextfield. In viewDidLoad() function of your viewcontroller that holds the both outlest use the following code

usernametextfield.textContentType = UITextContentType("")
passwordtextfield.textContentType = UITextContentType("")

After this you wont see autofill accessory option when you tap on your textfields.


Objective-C

if (@available(iOS 10, *)){
    self.tfEmail.textContentType = @"";
    self.tfPassword.textContentType = @"";
}

This worked for me.


Autofill is by default enabled for users. iOS saves all passwords in the keychain and make them available in keyboard in your apps. UITextView and UITextField automatically considered for AutoFill password. you can disable by specifying a content type that is neither username nor password but if the content type info already stored in keychain it will show in the quick bar. so better to assign empty UITextContentType type and it will not show quickbar.

Example:

  if #available(iOS 10.0, *) {
  self.textField.textContentType = UITextContentType("")
  } else {
  // Fallback on earlier versions
 }

This worked for ios 12 and 10:

if (@available(iOS 10, *)) {
    passwordTextField.textContentType = UITextContentTypeStreetAddressLine2;
}

if (@available(iOS 12, *)) {
    passwordTextField.textContentType = UITextContentTypeOneTimeCode;
}

Objective C version:

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {
    self.passwordTextField.textContentType = @"";
    self.confirmPasswordTextField.textContentType = @"";
}

where

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v)     ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

You could try different answers here that conclude its likely possible to remove accessoryview. But this leaves some bugs.

How to hide inputAccessoryView without dismissing keyboard

You could try to implement a custom keyboard perhaps, only for password fields. Also try to disable suggestions for your textfield, i think that also hides the accessoryView.

EDIT: No answer on apple forums on same question as of yet. Also i couldnt find anything regarding this in official uitextfield documentation.

https://forums.developer.apple.com/thread/82442


You can "turn off" the username/password combo detection by assigning a dummy textContentType to the password text field.

passwordFormField.textContentType = UITextContentType("dummy")

This turned off the key symbol for both the password field and the email field that preceded it, and in this way you don't use one of the predefined values and you avoid showing unrelated suggestions in the keyboard accessory view.


self.passwordTextField.autocorrectionType = NO;

It does not seem to work, the keychain sign still there,

self.passwordTextField.textContentType = UITextContentTypeName;

The code above does work, but if the users set up their Apple ID account, Then, the name of the apple id will be display on the keyboard you cannot disable it by set autocorrectionType to No, not sure if Apple still refines this autofill feature, it's quite buggy right now.


in response to @Gal Shahar Answer.

iOS 12 recognise password textFields by isSecureTextEntry property and not just by textContentType property.

Way Around to bypass Auto-fill Suggestion.

  1. set isSecureTextEntry property to false.

self.passwordTextField.secureTextEntry = NO;

  1. Add a UITextField Delegate Method and enable the isSecureTextEntry property.
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if (textField == self.passwordTextField && !self.passwordTextField.secureTextEntry) {
        self.passwordTextField.secureTextEntry = YES;
    }

    return YES;
}

NOTE: - Do NOT Use shouldBeginEditing UITextField delegate method it Will Still show Auto-filling Suggestion. Do NOT Use textFieldDidChange UITextField delegate method it Will Auto-delete the first charachter as the it Will happen after the first charachter is displayed. And 'secureTextEntry' will empty the field.


From what I can tell, Bem's answer does not work in iOS 12 and Gal Shahar's answer does not account for some edge cases (for example, if a user deletes multiple characters at once). I worked around this using an IBAction, thus removing the necessity to check for iOS version altogether. I'm just a beginner, so this might not be the "best" answer or the most efficient, but it made the most sense to me:

First, uncheck "Secure Text Entry" in the Storyboard or set it to "false"/"NO" via code for your password UITextField. This will prevent iOS from attempting to AutoFill.

Then, link your password UITextField to an IBAction. Mine is called on:

  • Editing did begin
  • Editing did change
  • Editing did end

The IBAction function I wrote determines the differences between a user's starting password and what has been inputed into the password UITextField and creates a new password based on this information:

class Login: UIViewController {
    var password = ""

    override func viewDidLoad() { super.viewDidLoad() }

    @IBAction func editPasswordField(_ sender: UITextField) {
        var input = Array(sender.text ?? "")
        var oldPassword = Array(password)
        var newPassword = Array("")

        //if character(s) are simply deleted from "passwordField" (not replaced or added to), "cursorPosition" is used to determine which corresponding character(s) need to also be removed from "oldPassword"
        //this is indicated by "input" comprising of only "•" (bullets) and being shorter in length than "oldPassword"
        var onlyBullets = true
        for char in input { if char != "•" { onlyBullets = false } }
        if onlyBullets && input.count < oldPassword.count {
            if let selectedRange = sender.selectedTextRange {
                let cursorPosition = sender.offset(from: sender.beginningOfDocument, to: selectedRange.start)
                let prefix = String(oldPassword.prefix(cursorPosition))
                let suffix = String(oldPassword.suffix(input.count - cursorPosition))
                input = Array(prefix + suffix)
            } else { input = Array("") }
        }

        //if no changes were made via input, input would comprise solely of a number of bullets equal to the length of "oldPassword"
        //therefore, the number of changes made to "oldPassword" via "input" can be measured with "bulletDifference" by calculating the number of characters in "input" that are NOT bullets
        var bulletDifference = oldPassword.count
        for char in input { if char == "•" { bulletDifference -= 1 } }

        //the only way "bulletDifference" can be less than 0 is if a user copy-pasted a bullet into "input", which cannot be allowed because it breaks this function
        //if a user pastes bullet(s) into "input", "input" is deleted
        //an edge case not accounted for is pasting a mix of characters and bullets (i.e. "ex•mple") when "oldPassword.count" exceeds the number of bullets in the mixed input, but this does not cause crashes and therefore is not worth preventing
        if bulletDifference < 0 {
            bulletDifference = oldPassword.count
            input = Array("")
        }

        //"bulletDifference" is used to remove every character from "oldPassword" that corresponds with a character in "input" that has been changed
        //a changed character in "input" is indicated by the fact that it is not a bullet
        //once "bulletDifference" equals the number of bullets deleted, this loop ends
        var bulletsDeleted = 0
        for i in 0..<input.count {
            if bulletsDeleted == bulletDifference { break }
            if input[i] != "•" {
                oldPassword.remove(at: i - bulletsDeleted)
                bulletsDeleted += 1
            }
        }

        //what remains of "oldPassword" is used to substitute bullets in "input" for appropriate characters to create "newPassword"
        //for example, if "oldPassword" is "AcbDE" and "input" is "•bc••", then "oldPassword" will get truncated to "ADE" and "newPassword" will equal "A" + "bc" + "DE", or "AbcDE"
        var i = 0
        for char in input {
            if char == "•" {
                newPassword.append(oldPassword[i])
                i += 1
            } else { newPassword.append(char) }
        }
        password = String(newPassword)

        //"passwordField.text" is then converted into a string of bullets equal to the length of the new password to ensure password security in the UI
        sender.text = String(repeating: "•", count: password.count)
    }
}

Constructive criticism is appreciated!


I think set all UITextField textContentType in form to UITextContentType("") or .oneTimeCode is not a clean solution. Enable/Disable isSecureTextEntry still give you the same issue.

@Gal Shahar 's Answer is nice but it is still not perfect. The masked char is not the same as the masked char that used in secure entry text from apple. It should use Unicode Character 'BLACK CIRCLE' (U+25CF) https://www.fileformat.info/info/unicode/char/25cf/index.htm

Also, it is not handling cursor movement. It will change the cursor position to the end of the text when inserting text in the middle. It will give you the wrong value when selecting and replacing text.

When you decide to use custom isSecureEntryText to avoid autofill password, here is the code:

Swift 5 (simple version)

@IBOutlet weak var passwordTextField: UITextField!

var maskedPasswordChar: String = "●"
var passwordText: String = ""
var isSecureTextEntry: Bool = true {
    didSet {
        let selectedTextRange = passwordTextField.selectedTextRange
        passwordTextField.text = isSecureTextEntry ? String(repeating: maskedPasswordChar, count: passwordText.count) : passwordText
        passwordTextField.selectedTextRange = selectedTextRange
    }
}

//this is UITextFieldDelegate
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    if textField == passwordTextField {
        //update password string
        if let swiftRange = Range(range, in: passwordText) {
            passwordText = passwordText.replacingCharacters(in: swiftRange, with: string)
        } else {
            passwordText = string
        }

        //replace textField text with masked password char
        textField.text =  isSecureTextEntry ? String(repeating: maskedPasswordChar, count: passwordText.count) : passwordText

        //handle cursor movement
        if let newPosition = textField.position(from: textField.beginningOfDocument, offset: range.location + string.utf16.count) {
            textField.selectedTextRange = textField.textRange(from: newPosition, to: newPosition)
        }
        return false
    }
    return true
}

Swift 5 (COMPLETE version with securing last char animation)

private struct Constants {
    static let SecuringLastCharPasswordDelay = 1.5
}

@IBOutlet weak var passwordTextField: UITextField!

private var secureTextAnimationQueue: [String] = []

var maskedPasswordChar: String = "●"
var passwordText: String = ""
var isSecureTextEntry: Bool = true {
    didSet {
        secureTextAnimationQueue.removeAll()
        let selectedTextRange = passwordTextField.selectedTextRange
        passwordTextField.text = isSecureTextEntry ? String(repeating: maskedPasswordChar, count: passwordText.count) : passwordText
        passwordTextField.selectedTextRange = selectedTextRange
    }
}

//this is UITextFieldDelegate
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    if textField == passwordTextField {
        //update password string
        if let swiftRange = Range(range, in: passwordText) {
            passwordText = passwordText.replacingCharacters(in: swiftRange, with: string)
        } else {
            passwordText = string
        }

        //replace textField text with masked password char
        updateTextFieldString(textField, shouldChangeCharactersIn: range, replacementString: string)

        //handle cursor movement
        if let newPosition = textField.position(from: textField.beginningOfDocument, offset: range.location + string.utf16.count) {
            textField.selectedTextRange = textField.textRange(from: newPosition, to: newPosition)
        }
        return false
    }
    return true
}

private func updateTextFieldString(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) {
    if isSecureTextEntry {
        if string.count == .one, let text = textField.text {
            let maskedText = String(repeating: maskedPasswordChar, count: text.count)

            var newMaskedText = String()
            if let swiftRange = Range(range, in: maskedText) {
                newMaskedText = maskedText.replacingCharacters(in: swiftRange, with: string)
            } else {
                newMaskedText = text + maskedText
            }

            textField.text = newMaskedText
            secureTextAnimationQueue.append(string)
            asyncWorker.asyncAfter(deadline: .now() + Constants.SecuringLastCharPasswordDelay) { [weak self] in
                self?.securingLastPasswordChar()
            }
        } else {
            secureTextAnimationQueue.removeAll()
            textField.text = String(repeating: maskedPasswordChar, count: passwordText.count)
        }
    } else {
        textField.text = passwordText
    }
}

private func securingLastPasswordChar() {
    guard secureTextAnimationQueue.count > .zero, isSecureTextEntry else { return }
    secureTextAnimationQueue.removeFirst()
    if secureTextAnimationQueue.count == .zero {
        let selectedTextRange = passwordTextField.selectedTextRange
        passwordTextField.text = String(repeating: maskedPasswordChar, count: passwordText.count)
        passwordTextField.selectedTextRange = selectedTextRange
    }
}

This worked for me:

NOTE: try putting this code on the password, password confirm (if applicable), AND email textfields. I was not putting it on the email textfield and it was still popping up for the two password fields.

if #available(iOS 12, *) {
     // iOS 12: Not the best solution, but it works.
     cell.textField.textContentType = .oneTimeCode
} else {
     // iOS 11: Disables the autofill accessory view.
     cell.textField.textContentType = .init(rawValue: "")
}
