2FA Authenticator - Autheris

Secure your accounts with Autheris — a privacy-first two-factor authentication (2FA) app for iPhone, iPad, Mac and Apple Watch.

Autheris generates the time-based one-time passwords (TOTP) that protect your most important accounts, and keeps the secrets behind them on your device. No account, no sign-up, no ads.

NOW ON APPLE WATCH
• One Code at a Time — Your codes on your wrist, each with a live countdown. Turn the Digital Crown to move between them.
• Read-Only by Design — There is no copy, no editing and no settings on the watch. Your iPhone stays the one place codes are managed.
• Works Without Your iPhone — Codes are generated on the watch itself, so they keep counting down with your phone out of reach or switched off.

KEY FEATURES
• One-Tap Codes — Copy a code with a single tap. The clipboard clears itself after 60 seconds.
• Pin and Reorder — Pin the codes you use most to the top, and drag the rest into whatever order suits you.
• Folders — Sort your tokens into colour-coded folders and filter your list with a tap. Off until you turn it on in Settings.
• Recently Deleted — Delete a code by mistake? It stays on your device for 7 days, ready to restore.
• QR Scanning — Add an account by scanning a QR code, or choose a screenshot from your photo library.
• Time-Based and Counter-Based Codes — TOTP for almost every service, and HOTP for the ones that hand you a counter instead, each with SHA-1, SHA-256 or SHA-512 and 6 to 10 digits. If a service rejects your codes, the algorithm is editable per account.
• Import — Bring your token generator accounts across from Google Authenticator, Aegis, andOTP or 2FAS.
• Search — Find any account instantly, however long your list gets.
• Issuer Icons — Familiar brand marks so you can spot an account at a glance.
• Countdown Ring — A clear, colour-customisable ring shows how long each verification code has left.

PRIVACY AND SECURITY
• Face ID / Touch ID Lock — Locks when opened, and again after 30 seconds away.
• Blurred When Backgrounded — Content blurs when you switch apps, and your codes are hidden in the app switcher.
• Protected While Recording — Codes are covered whenever your screen is being recorded or mirrored.
• Secrets Stay on Your Device — Codes and setup keys are kept in your device's Keychain and never leave it unless you export them or turn on iCloud Sync.
• Encrypted Backups — Save an AES-256-GCM encrypted backup protected by a password only you know.
• Optional iCloud Sync — Off by default. When you enable it, your secrets are end-to-end encrypted by CloudKit, and the developer cannot read them.
• No Account, No Tracking — Nothing to sign up for, no analytics, no advertising. Autheris is open source.

Install Autheris, add an account, and keep your second factor — and your 2-step login — under your own control.
