I see, thanks. Have you considered moving to Bitwarden?
VaultWarden is a good compromise (offers the choice of SQLite or Postgres under the hood), putting you in charge of the primary server, but it is honestly overkill for a single personal user compared to a kdbx file on a webdav share.
Maybe. I'm looking into VaultWarden for my personal passwords because keeping a KBDX file up to date on iOS is painful (without a corporate cloud backing).
Good tip, I'm going to check that out!
