To me his approach / setup is rather simple, it is basically KeePassXC + Aliasing + MFA, password generation and expiry and TOTP are built in functions. Syncing is simple enough (just any clouds), Passkey is optional.
An inherited friction point for Syncing database through encrypted clouds rather than NAS like synology, is that when you access via Android (not sure about IOS), the phone will keep a cache and open the same cache over and over again, rather than opening the latest version.
So personally I prefer using personal NAS to sync across devices, and Cloud will be used as a backup only.
Really? Simpler than what I have suggested? Iām not even sure thatās objectively true but this is a subjective matter so I guess I understand. Though I personally cannot see why.
I am not saying @kissuās approach is āsimpler" than yours, I am simply saying it is simple.
I personally wont rely on cloud based password managers due to their past incidents. There is nothing wrong with your approach, it is just my preference.
