ReceptionRating · Positive reviews · Number of ratings

Optimal Authenticator holds the better App Store score, 3.0 against 2.0. That said, the two scores are not equally well evidenced: SurePassID Push Authenticator has 21 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 40% of SurePassID Push Authenticator's written reviews are positive against 0% of Optimal Authenticator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

SurePassID Push Authenticator ships an update every 4 months, Optimal Authenticator every 3 months. The most recent releases landed on September 11, 2026 and September 19, 2026 respectively.
