Both KeepassXC on desktop and KeepassDX on mobile support autofill, passkeys, and TOTP. Syncing to mobile devices is handled by Syncthing (I use BasicSync on Android) and is quite seamless after setup.
Integration with mobile browsers and other applications is handled by the OS-level autofill service (at least on Android). Trusting a third party app that is completely open source and has a ton of eyes on it? I don’t see a problem with that.
Selfhosting is literally the entire point, since who more can you trust with your most sensitive information than yourself? And even if you don’t trust yourself with being able to keep good backups and following the 3-2-1 rule, you’re more than welcome to sync with a third party cloud provider of your choosing since the password file is fully encrypted.

Why is it that every time i comment about keepass, its because some web based password manager once again broke, got hacked, or stopped development. Keepass users just stay winning :)
