I used to use KeePassXC and it does work wonders. However now I self-host Vaultwarden on my Raspberry Pi 4 NAS. The app on Android is Bitwarden, and you can then update the server to point towards the self hosted Vaultwarden server. In my Google Keyboard, I then have the password entries show up in apps and webpages
