Affected version

1.0.10

Steps to reproduce the bug

1. Install app implementing its own keyboard for passwort entry (e.g. banking app: https://play.google.com/store/apps/details?id=com.starfinanz.mobile.android.dkbpushtan)
2. Open the described app in point 1.
3. Try to enter password and check for autofill popup or tag

Expected behavior

When using https://f-droid.org/de/packages/de.jbservices.nc_passwords_app as standard autofill service, then the popup appears. So still there seems an issue with password field detection that works with other apps.

Actual behavior

My TAN banking app is providing its own keyboard when started. If Nextcloud Passwords is used as autofill service, my banking app is not showing "password autofill overlay or popup dialog".

Additional information

No response

Start by reproducing the issue on LineageOS 21 with the linked banking app and compare Nextcloud Passwords with the alternative autofill service. Trace the Android autofill-service handling for password fields when the target app provides its own keyboard. Done means the overlay or popup appears in the affected app without breaking the existing autofill behavior.
