# Protectimus SMART vs Authenticator App

The clearest difference is rating: Authenticator App at 4.5 against Protectimus SMART's 3.9. Authenticator App also leads on ratings volume (138 vs 18) and update cadence (every 4 months vs every 7 months). Protectimus SMART's advantage is in-app purchases (none vs 3). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. Authenticator App sells 3 in-app purchases, starting at $2.99 per 7 days. Protectimus SMART asks for nothing beyond the download.

Authenticator App holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: Authenticator App has 138 ratings behind it against 18, so its average is the more settled of the two. 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.

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.
