What are LessPass and Spectre?
LessPass
LessPass is an open-source password manager that generates unique passwords deterministically from a master password and site details. Because nothing is stored, there is no vault to sync or back up.
- Deterministic password generation
- No vault to store or sync
- Browser extensions and mobile apps
- Optional self-hosted profile sync
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
