Where has the forgotten password button gone? My device is running Android 5.0 Lollipop or above and I have forgotten my lock screen password. After trying multiple times without luck, I do not see an option to reset my password using my Google account credentials. Why is this option not appearing?
This option seems to be have removed by Google in Android 5.0 and above and there is no longer an official way to reset your lock screen password.

Resetting your password using Android Device Manager also often fails as there is already a screen lock set.

Check the locked-out tag for information that may help with your issue.
