What are Passit and Spectre?

Passit

Passit is a self-hosted, open-source password manager with browser extensions. It encrypts credentials client-side before syncing them to your own Django-based server and supports group sharing.

  • Client-side encrypted vault
  • Browser extensions for Chrome and Firefox
  • Group password sharing
  • Self-hosted Django backend

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
