MinOTP

MinOTP is a private two-factor authenticator for iPhone and Apple Watch. Minimum effort, maximum security.

WHAT IT DOES • Time-based and counter-based one-time codes (TOTP and HOTP) with SHA-1, SHA-256, SHA-512 and MD5, 6 to 8 digits, any period. • Add accounts by scanning a QR code, pasting an otpauth:// link, or typing the secret. • Tap a code to copy it. Codes count down with a ring, a bar, or flipping flaps, depending on the skin you pick.

ON YOUR WRIST • The Apple Watch app shows every account counting down, with a zoomed dial for the one you need and a Next Code button for counter-based accounts. • A watch-face complication (a lock inside the countdown arc) opens your list with one tap. • Four list densities on the watch, from comfortable to a tight ticker.

MAKE IT YOURS • Seven skins: Meridian, Cipher, Stamp, LED Clock, Departures, LCD and Flipper. • Colour labels to mark the accounts that matter most. • Folders when you want them, one simple list when you don't. Drag to reorder. • Service icons or emoji, search, light and dark mode, English and German.

SWITCHING FROM OTP AUTH • Opens OTP Auth backup files (.otpauthdb) and single-account files (.otpauth) directly from Files, AirDrop or Mail. Type the backup password on your phone and every account, folder and icon comes across. • Exports backups in the same format, so you are never locked in.

PRIVATE BY DESIGN • No account, no server, no analytics, no ads. MinOTP never connects to the internet unless you turn on iCloud sync. • Secrets are encrypted on the device with a key in the Keychain and protected by Face ID, Touch ID or a passcode. • Optional iCloud sync encrypts your vault on the device before it reaches your private iCloud database, so Apple only stores ciphertext. • Widgets for the home and lock screen, and Siri: "Get my GitHub code in MinOTP."
