TOTP Authenticator holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: TOTP Authenticator has 167 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 100% of Protectimus SMART's written reviews are positive against 65% of TOTP Authenticator's, so the app with the better star average is not the one people write more warmly about.
Protectimus SMART ships an update every 7 months, TOTP Authenticator every 9 days. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
