KeePass and syncthing. I use Keepass2 on a Linux desktop and laptop, KeePassDX on Android, and use syncthing to keep everything synchronized and up to date, also using an old raspberry pi to act as a central server for syncthing.

Modifying the database on one device seamlessly updates the other devices once they’re visible on the network, everything works beautifully and is very easy to set up on a local network.

Pretty much default configuration all the way around, just gotta make sure syncthing starts on boot. Just did a brief search, syncthing seems to have a MacOS fork, and iOS will need Möbius Sync, which is paid but the free tier offers 20MB storage sync which is overkill for KeePass.

Minor system modification that would life-changingly benefit >90% of the population, for this generation and the next, while leaving the other 10% relatively unaffected, blocked with no support after decades of waiting: “Absolutely not, this is an unprecedented proposal, fuck you for even considering it”

Major system modification that uproots all precedent, completely changes all the existing procedures, massively benefits two people while fucking over everyone else, passed with unopposed unanimous support three weeks after submission: “Look, someone was gonna push the ‘Fuck You’ button eventually anyway, might as well do it now”
