Authenticator App holds the better App Store score, 4.5 against 3.9.

Written reviews complicate that: 57% of Protectimus SMART's written reviews are positive against 50% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Protectimus SMART ships an update every 7 months, Authenticator App every 4 months. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
