@J12t honestly, I don't care about any of my non-work google accounts except those on the phones and I'm working to reduce those

password manager is KeePassX with local files. Backups are done as part of filesystem, but also to some extra places (haphazardly) since I need the password manager to open my backups :)

KeePass files are pretty common, several applications can open them

I could GPG encrypt the KeePass files for extra encryption and store them on Nextcloud for offsite
