2FA Two Factor Authentication
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Secure every login with 2FA codes that never leave your iPhone. Scan a QR code, import from Google Authenticator, lock with Face ID. Try Premium free.
Authenticator protects your online accounts with two-factor authentication (2FA). Scan a QR code once and get a fresh 6-digit sign-in code every 30 seconds, generated right on your iPhone. Even if your password leaks, nobody can sign in without your phone.
WORKS WITH EVERY SERVICE THAT SUPPORTS 2FA
• Email, social media, banking, crypto exchanges, gaming, cloud storage and work accounts
• Google, Microsoft, Facebook, Instagram, Amazon, Coinbase, Binance, Discord, GitHub, Dropbox and thousands more
• Time-based (TOTP) and counter-based (HOTP) codes, SHA-1, SHA-256 and SHA-512, 6 to 8 digits
• Steam Guard codes
ADD ACCOUNTS IN SECONDS
• Scan the QR code a website shows when you turn on two-factor authentication
• Pick a screenshot of the QR code from Photos
• Or type the setup key by hand
• Move all your accounts from Google Authenticator in one scan
SAFER THAN TEXT MESSAGE CODES
• Codes are generated on your device and never travel over the network, so SIM swaps and phishing texts can't steal them
• Works offline and in airplane mode
• Copied codes expire from the clipboard automatically
• See the next code before the current one runs out
LOCKED DOWN AND PRIVATE
• Face ID, Touch ID and a 6-digit PIN, with auto-lock
• Privacy screen hides your codes in the app switcher
• Secrets are stored encrypted in the iOS Keychain
• No account, no sign-up, no ads. We have no servers that hold your accounts and we never see your codes.
