OfflineAuth- 2FA Authenticator

OfflineAuth is a fast, private two-factor authentication (2FA) app for your social media, email, gaming, and work accounts. Generate time-based one-time passwords (TOTP) right on your phone — no sign-up, no cloud, no tracking.

Add accounts in seconds by scanning a QR code from Instagram, Facebook, X (Twitter), Google, Discord, GitHub, and any service that supports standard authenticator apps. No QR code? Enter the setup key manually.

PRIVATE BY DESIGN

OfflineAuth does not collect personal data. There are no ads, no analytics, and no servers. Your 2FA secrets are stored only on your device and encrypted locally. Camera access is used only for QR scanning — images are processed on-device and are not saved or sent anywhere.
Replace SMS codes with something safer. Keep all your 2FA codes in one secure place — fully offline, fully under your control.
