What are Bitwarden and Spectre?
Bitwarden
Bitwarden is an open-source password manager offering encrypted vaults, sharing, and apps on every platform, with a self-hostable server. It targets individuals and teams wanting an audited password manager. It is deployed via Docker.
- Encrypted cross-platform vaults
- Secure password sharing
- Regular third-party audits
- Self-hostable official server
Spectre
Spectre, the successor to Master Password, is an open-source stateless password manager. It derives strong, unique passwords from your name and a master password rather than storing them in a vault.
- Deterministic password derivation
- No vault to store or sync
- Cross-platform clients
- Works fully offline
