Authenticator is the simple, secure way to protect every online account you own with two-factor authentication (2FA). Generate time-based one-time passwords (TOTP) right on your iPhone and sign in to the services you love with a fresh verification code in seconds — no more waiting on slow SMS texts or digging through screenshots. A password alone is no longer enough — that extra layer of verification is what stands between a leaked password and a hijacked account. Built for anyone juggling dozens of logins across email, banking, work, social media, gaming, and crypto, Authenticator keeps all your security codes in one calm, organized place. Whether you're turning on 2FA for the first time or switching to a new phone, it makes staying protected effortless. The interface stays clean, fast, and clear, with everything you need just one tap away. WHY YOU'LL LOVE IT • Add accounts in one tap — scan a QR code and you're protected instantly • Manual setup with clear, step-by-step guides for sites that hide their secret keys • Automatic 2FA code generation with an easy-to-read countdown timer • One-tap copy so you can paste your OTP and log in fast • Face ID, Touch ID, or PIN lock keeps your codes private • Search, filter, custom icons, and themes to organize every account your way NEVER LOSE ACCESS • Encrypted cloud backup so you can restore your accounts on any device • Automatic multi-device sync in real time — set it up once • A recently-deleted recovery bin rescues codes you remove by mistake • Easy import from Google Authenticator, screenshots, files, or other apps • Import and export to move between phones with total confidence PRIVATE BY DESIGN Your 2FA data is fully encrypted, both on your device and in the cloud. Only you can unlock your verification codes — we can't see them, and neither can anyone else. Authenticator is not a password manager and never stores your usernames or passwords. It does one job, and it does it exceptionally well. WORKS EVERYWHERE, EVEN OFFLINE Generate one-time passwords anytime — on a plane, traveling abroad, or with no signal at all. Your codes are always ready the moment you need them. WORKS WITH THE SERVICES YOU USE Authenticator is compatible with thousands of websites and apps, including Google, Microsoft, Facebook, Instagram, Amazon, X, LinkedIn, PayPal, Coinbase, Binance, Discord, Steam, Roblox, GitHub, and Dropbox. If a service supports TOTP-based two-factor or multi-factor authentication (MFA), it works here. A SECURITY CHECK THAT HAS YOUR BACK A built-in security check flags weak setups and accounts that still need 2FA, so you always know your protection is complete. Instead of guessing whether you forgot something, you get a clear view of where you stand and can close any gaps in a few taps. Tired of insecure SMS codes? Authenticator gives you a faster, safer, and more reliable way to sign in every single day. Two-factor authentication doesn't have to be complicated — here, it simply works.
