A local browser-based password manager backed by a single private key — a mnemonic of 12 words. It deterministically generates different passwords for different websites and users, and supports password changes and updates for the same site and user.
The only thing that must be stored is the master key for all passwords. This key must never be exposed or lost.
Optional encrypted cloud backups via the Nostr protocol using nip04, kind:1 events, and key derivation from the seed phrase. Local session encryption with password-based AES protection stored in localStorage. Privacy-focused and portable: works entirely offline, mobile-friendly, and avoids central storage or server reliance.
