The 2FA authenticator for people with more than five accounts. TOTP Authenticator generates the six-digit verification codes you need to sign in to Google, Microsoft, Facebook, Amazon, GitHub, PayPal and 1000+ other services — but with the cloud sync, browser push, and widgets that the other authenticators don't give you. — WHY PEOPLE SWITCH — • ENCRYPTED CLOUD SYNC — Back up to iCloud or Google Drive. Your data stays in your own cloud account; you stay in control. Restore on a new Phone in seconds. • PUSH CODES TO YOUR BROWSER — Pair our Chrome or Firefox extension once. From then on, one tap on your phone copies the right 2FA code to your desktop clipboard — ready to paste. Your security key never leaves your phone. We never see your codes. • LOCK SCREEN & HOME SCREEN WIDGETS — Pin your most-used accounts to your Lock Screen or Home Screen. Glance, tap, copied. Live countdown built in. • YOUR DATA TRAVELS WITH YOU — Already used our app on a different platform? Encrypted backups round-trip cleanly between iOS and other platforms via Google Drive. — PRIVACY BY DEFAULT — • Face ID or Touch ID lock. • Tap-to-reveal — codes stay hidden in the list until you tap. • Screen Security blocks screenshots and screen recording, on by default. • No analytics. No tracking. No servers that can leak your secrets. — ORGANISED THE WAY YOU THINK — • Eight colour-coded categories: Personal, Work, Social, Entertainment, Tools, Finance, Favourites, Other. • Instant search with one-tap category filter. • Drag to reorder. Pin to Favourites for one-tap access. • Pick an issuer icon from our library, or auto-match when you scan a QR code. • Add accounts by camera, by photo library QR scan, or by typing the key manually. • Works offline — codes are generated on your device. No network required to sign in. — WORKS WITH — Google, Apple ID, Facebook, Amazon, Microsoft, GitHub, PayPal, Dropbox, LinkedIn, Twitter / X, Instagram, Yahoo, WordPress, Epic Games, Blizzard, GoDaddy, Bitbucket, TeamViewer, Dashlane, Evernote — and 1000+ other services that support the RFC 6238 TOTP standard that Google Authenticator uses. — WHAT'S NEW IN v1.23 — Rebuilt from the ground up. Faster, cleaner, fully localised in English, German, and Japanese. iCloud sync rewritten for reliability. New Lock Screen widget. New search with category filter. New tap-to-reveal privacy mode. — PREMIUM — Cloud Sync and Browser Push are part of TOTP Premium — a one-time purchase, not a subscription. Try the app free; upgrade if and when you need them. Questions, bug reports, requests? Use the in-app Contact form or email hello@binaryboot.com — we read every message. App-based 2FA only. Does not receive or generate SMS codes.
