An online database is still a file ultimately. A SQL or other DB file stored in a webserver, accessed through a web interface.
Vaultwarden, etc, are the same, only the database file is less directly visible IMO. Keepass IMO is simple. The DB in a bespoke format, stored outside the application.
You could put the vault in system32 and name it "trustedinstaller.log", and if someone saw you had keepass they wouldn't even know where your vault is.
Given the number of well documented breaches of online password vaults, I would much rather do a private device to device sync via syncthing and keep it out of webservers.
My guy, the line is a status symbol one earn by paying bonuses up front or letting their company pay.
There is no greater good here. Line cutters aren't somehow immoral.
If everyone boarded in logical patterns of staggered odd window even window odd middle even middle odd aisle even aisle boarding, with no pairs or groups allowed, you'd be on to something.
But it falls apart the moment you look at how it's actually done. Status and rewards, and seat class, then whatever is left. Cutting in line because you didn't spring for an $80 seat upgrade that amounts to "better" padding in the headrest and 1 extra inch in your legroom is insane.
