Tessera Authenticator: 2FA

No account. No servers. No network requests at all.

Tessera keeps your two-factor accounts on your iPhone and Mac and generates every verification code on the device itself. There is nothing to sign up for and no server to trust: the app ships without a network entitlement, so it makes zero outbound requests.

WHAT IT DOES
• TOTP, HOTP and Steam Guard codes
• Add accounts by QR scan, photo import, paste, manual entry, drag and drop, or an otpauth:// link
• AutoFill one-time codes, so you rarely need to open the app
• Widgets with tap-to-reveal for the accounts you use most
• Folders and favorites once your list gets long
• App lock with auto-lock, plus capture-aware redaction that hides codes from screenshots and screen recordings
• iCloud Keychain sync, end-to-end encrypted by the OS

A REAL MAC APP
Not an iPad build stretched to fit. Pro adds a native Mac app with a menu bar extra, so the code you need is one click from the field you are typing into.

PRIVACY YOU CAN CHECK
Zero third-party SDKs. No analytics, no tracking, no ads, no App Tracking Transparency prompt. App Privacy reads Data Not Collected, because there is nothing to collect.

BRING YOUR ACCOUNTS WITH YOU
Import from another authenticator using otpauth-migration QR codes, or through Credential Exchange. Export an encrypted backup whenever you like — including the day you decide to leave.

FREE AND PRO
Free stores a set number of accounts; deleting one frees its slot. Pro unlocks unlimited accounts, the Mac menu bar app, widgets, folders and favorites, and automatic encrypted backup.

Pro Lifetime is a one-time purchase: pay once and keep it. If you would rather subscribe, Pro is also available monthly or yearly, each with a one-week free trial.

Built in SwiftUI for iOS 26 and macOS 26, and actively maintained.

Subscriptions renew automatically unless auto-renew is switched off at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.
