Alternatives to Google Authenticator

The short version
Microsoft Authenticator is the strongest Google Authenticator alternative, generating 2FA codes with cloud backup and push approvals on a huge, highly rated base. For broad service support, Authenticator app (Maxima) covers 1000+ services with Apple Watch sync. Most others offer the same TOTP code generation with encrypted vaults. Each shares Google Authenticator's core: scan a QR code and generate time-based one-time codes to secure your logins.
The app you searched for

See how Google Authenticator and these apps ranked on past days with the free App Store rank history tool.
Every app in our database carries a dense vector embedding derived from its title, subtitle, full description, and category metadata. To find apps similar to Google Authenticator, we compute cosine distance against every other app and keep the closest 30. The similarity score shown on each pick is 1 - distance/2 clamped to [0,1] — 100% means the embedding spaces are identical, 0% means orthogonal.
Apps from Google Authenticator's own developer are left out. The 10 most similar of the rest are ordered by App Store rating times the logarithm of their rating count, so a 4.8-star app with 100,000 ratings ranks above a 4.5-star app with 200 ratings.
