I use KeePass + KeeAnywhere. KeeAnywhere will sync with a wide variety of cloud storage providers. Or your own S3 data bucket server (can be self hosted or on Amazon), if you prefer. Does pretty much the same thing though with versioning. Auto filling in Firefox is done with KeePassHttp-connector on the Firefox side and the KeePassHTTP plugin in KeePass. Similar to what you describe.

Are you trying to use a passkey to unlock the database or for authenticating with other websites? KeePass can natively do TOTP. There’s also plugins to do that. Including one that allows KeePass to be a native Windows 11 PassKey Provider.
