## What is Authenticator?

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.

PREMIUM
• Unlimited accounts
• iCloud sync across your iPhone and iPad, end-to-end encrypted by iCloud Keychain
• Password-protected encrypted backups
• Password vault with a strong password generator
• Private browser that saves no history, cookies or site data
• Show any account as a QR code to move it to another device
• Custom app icons

The free plan includes 1 account. Try Premium free for 3 days, then $9.99 per week. Cancel anytime.
