Open Source Password Manager
A password manager is the one app you have to trust completely - it holds every credential you own. The open source options below earn that trust differently than closed-source vaults: the encryption code is public, independent audits actually happen, and most of them can run on your own server, so a vendor breach or a sudden pricing change never locks you out of your own secrets.
Vaultwarden
Self-hosted Bitwarden-compatible server in Rust, light enough to run where the official service is too heavy
