BlackVault Authenticator
Your sign-in codes. On your phone. Nowhere else.
Coming soon to Google Play
An offline authenticator app for Android with fingerprint, face or PIN lock, encrypted storage and an encrypted backup you control. No accounts, no ads, no tracking.
Features
What it does, in its own words
Codes for the sites you use
Generates time-based and counter-based one-time codes for any site or service that supports authenticator apps.
Fingerprint, face or PIN lock
The app asks you to unlock it with your fingerprint, face or your phone's screen lock when it opens.
Encrypted on your phone
Your codes are stored encrypted, with the key kept in hardware-protected key storage on phones that support it.
Encrypted backup you control
Export a backup file protected by a passphrase only you know.
Works fully offline
The app has no internet permission, so it cannot send anything anywhere.
No ads. No tracking. No accounts.
There is nothing to sign up for and no analytics or advertising code in the app.
Bring your codes over
Import accounts from Google Authenticator, or add accounts by scanning a QR code or typing the setup key.
