Both are free to download. Authenticator App ◦ sells 3 in-app purchases, starting at $6.99 per month. Auth0 Guardian asks for nothing beyond the download.
Authenticator App ◦ holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Authenticator App ◦ has 982 ratings behind it against 114, so its average is the more settled of the two. Written reviews complicate that: 15% of Auth0 Guardian's written reviews are positive against 7% of Authenticator App ◦'s, so the app with the better star average is not the one people write more warmly about.
Auth0 Guardian ships an update every 3 months, Authenticator App ◦ every 2 months. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
