Handling failed authentication about cordova-plugin-android-fingerprint-auth HOT 4 CLOSED

published v0.0.13 to address this issue.
Plugin now returns error "Too many attempts. Try again later." if disableBackup is set to true.
Also added parameter maxAttempts to set number of failed attempts to fewer than 5 attempts.

I don't know if this is consistent across all device manufacturers, but the max number of attempts is 5 failed attempts. When this happens an error is thrown and onError() gets called. From there I am triggering the authentication screen regardless of the disableBackup parameter.

I could modify this to check the disableBackup parameter and if it is disabled I could fail back to the calling application.

There is also an onAuthenticationFailed() method in the FingerprintUiHelper class. I could create a parameter to set the number of attempts to less than 5 and track the failed attempts in the onAuthenticationFailed() method. I could then fail over to the authentication screen or back to the application depending on the disableBackup parameter.

How many failed attempts were you wanting to allow?

Checking disableBackup in onError() would definitely work.
Also adding another parameter along the lines of numAttempts could be useful.

5 attempts works fine for me. Mostly, being able to handle what happens in my application when onError() is called and disableBackup is true would be useful. (e.g. canceling the dialog, going to a different page, logging out a user, etc.)

Thank you for your response and your time!

I just tested that out and it works great.

Thanks!
