iOS Use Strong Password not working

SDK Version: 42.0.1
Platforms: iOS (v. 14.7.1)
Device : iPhone 12 pro max ;

Hi everyone ! After several attempts to integrate the autofill iOS’s functionality with the prop newPassword of TextInput component, I finally decided to ask help.

I have a simple registration form with three fields:

  • username
  • password
  • password verification

Here is the simplest code which is supposed to work but which does not :

<View style={styles.container}>
				placeholder="confirm password"
			<TouchableOpacity onPress={handleSubmit} >

Expected behavior

I would like the password autofill feature to fire at the focus of one of the two inputs that have the newPassword property like this :

In fact, the above screenshot comes from the application running under Expo and the feature works fine.

I specify that when I touch the input username, auto fill password only works on the first input password

Okay, now when I build my app to test it via TestFligth, these features don’t work at all. I know there is some configurations to set up :

  • My phone’s keychain is active.

  • AutoFill Credential Provider is active on App ID Configuration

  • Here is my app.json iOS configuration :

"ios": {
      "supportsTablet": true,
      "bundleIdentifier": "com.myIdentifier.identifier",
      "buildNumber": "1.0.4",
      "associatedDomains": [
      "entitlements": {
        "": "true"

I can’t seem to find where something is missing ! Maybe in the app.json ?
