Authenticator App holds the better App Store score, 4.4 against 4.2. That said, the two scores are not equally well evidenced: Authenticator App has 547 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 50% of Duo Authenticator's written reviews are positive against 38% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.

Duo Authenticator ships an update monthly, Authenticator App every 9 days. The most recent releases landed on October 9, 2026 and October 8, 2026 respectively.
