CipherNook
Your 2FA backup codes belong in a safe place, not in Notes.
Encrypted, offline vault for your 2FA recovery codes.
Why CipherNook exists
Turning on 2FA hands you eight to ten one-time backup codes per service, and most people paste them into Notes, screenshot them, or lose them — then get locked out when they switch phones. There is no purpose-built, encrypted, offline place for recovery codes specifically, kept deliberately separate from your authenticator.
What CipherNook does
- Store recovery codes per service, grouped and searchable
- Mark each code used or unused with a single tap
- Copy to clipboard with automatic clear after 30 seconds
- Biometric / device-credential unlock, with auto-lock on background
- Encrypted at rest (SQLCipher + Android Keystore-wrapped key)
- Screenshots blocked and no internet permission at all
- Password-protected encrypted export and import
- Fully offline — no account, no subscription
