Agreed, Keepass file synced on Google Drive. Using this for 4+ years now with 0 issues. Syncs across desktop (Keeweb), Android (keepassAndroid) and ioS (StrongBox). Takes 5-10 seconds to sync.
Also zero need to give any application permissions to access my Google Account. Using native google drive apps on all services to sync the file (just using file picker dialogs with drive app installed).
Got my non tech parents setup on this. 0 questions asked once I set it up.
Also have my partner and I on the same setup...just works.
KeePassDX has its own keyboard that lets you securely input usernames, passwords, and other fields without exposing sensitive data to the clipboard (handy when autofill doesn't handle the field).
I tried both KeepassDX and Keepass2Android. In the end I went with Keepass2Android. I don't remember why I chose Keepass2Android in the end, but I can definitely recommend it.
But to some extent it took her compromised passwords to finally start using everything.
