TOTP Authenticator holds the better App Store score, 4.7 against 3.5.

Written reviews complicate that: 100% of Mobile OTP Authenticator's written reviews are positive against 66% of TOTP Authenticator's, so the app with the better star average is not the one people write more warmly about.
Mobile OTP Authenticator ships an update every 8 months, TOTP Authenticator every 11 days. The most recent releases landed on September 28, 2026 and October 13, 2026 respectively.
