I use Keepass but I recommended Bitwarden to less nerdy family members as it syncs out of the box & does what they need it to do. Sync is simple enough to set up with Keepass & the big plus for me is that it allows storage of files/documents. Last time I checked this was a limited/paid feature on Bitwarden
Pi5 8GB with SSD. Only 1 user but often sharing folders with others including Memories photo sharing add on. Syncs between several machines & mobile. Also syncs Joplin notes. Pi5 also hosts variety of other (lightweight) stuff with no issues at all (Portainer, Nginx Proxy Manager, Linkwarden etc).
Previously hosted on Pi4B (4GB) with external hard drive. I’ve found the Pi5 + SSD faster & more robust so for me it’s been a worthwhile upgrade
