Passnyx — Password manager

Your passwords, on your Android. No cloud, no account, no one else sees them.

An Android password manager that lives only on your device. Triple-layer encryption at database, field, and master-key level. No server, no sync, no tracking — if you lose your phone, you lose your data (that's why there's encrypted backup). With native autofill, built-in TOTP authenticator, and biometric unlock.

Password generator

Generate strong passwords with the length and characters you want, and Passnyx alerts you if any of yours has been publicly leaked.

Why we built it this way

Cloud-based password managers (Bitwarden, 1Password, LastPass) are convenient, but they imply your passwords travel over the internet and live on a third-party's servers. For users who'd rather not trust the cloud, that architecture is excessive attack surface.

Passnyx is the opposite: triple-layer local encryption (SQLCipher at the database, AES-256-GCM per field, Android Keystore for the master key), all offline, no sync. If you want backup, you export an encrypted .passnyx file or to your own Google Drive — your call.
