TwoFac vs 2FA4G

Your two-factor codes. Private, secure, always available. TwoFac is an offline authenticator that keeps your one-time passwords exactly where they belong — on your device. No account to create, no server to trust, no subscription to manage. Just your codes, ready when you need them. PRIVATE BY DESIGN Every secret is encrypted and stored locally using your device's secure storage. TwoFac has no backend, no analytics, and no data collection of any kind. Your codes never leave your phone unless you explicitly export a backup. SIMPLE TO USE • Scan a QR code to add any TOTP account in seconds • Enter codes manually with full field validation • Copy any token with a single tap • See exactly how long your code is valid with a live countdown • Organize accounts into folders to keep things tidy BACKUP WHEN YOU WANT Export an encrypted backup file protected by a password you choose. Save it to iCloud Drive, share it to Files, or keep it anywhere you like. Restore it on any device running TwoFac. Your backup, your rules. SECURE AT REST • Secrets encrypted with AES-GCM on-device • Optional biometric app lock (Face ID / Touch ID) • Automatic re-lock after a configurable timeout • Screenshot prevention in the app switcher COMPATIBLE WITH EVERYTHING TwoFac works with any service that supports TOTP (RFC 6238): Google, GitHub, Dropbox, Notion, Stripe, Amazon, Cloudflare, Twitter, Discord, and thousands more. FREE. ALWAYS. TwoFac is and will always be free to use. No ads. No in-app purchases. No premium tier. If you find it useful, a small donation keeps the project alive — but there's no obligation whatsoever.
