# Authenticator App vs Auth

The clearest difference is review sentiment: Auth at 87% against Authenticator App's 38%. Authenticator App's advantage is rating (4.4 vs 4.2). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Authenticator App sells 5 in-app purchases, starting at $6.99 per 7 days and Auth sells 2 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator App holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 547 and 365 respectively. Written reviews complicate that: 38% of Authenticator App's written reviews are positive against 87% of Auth's, so the app with the better star average is not the one people write more warmly about.

Authenticator App ships an update every 9 days, Auth every 2 weeks. The most recent releases landed on October 8, 2026 and October 4, 2026 respectively.
