# Auth vs Authenticator

The clearest difference is review sentiment: Auth at 100% against Authenticator's 50%. Auth also leads on rating (5.0 vs 4.4). Authenticator's advantage is in-app purchases (none vs 5) and update cadence (every 5 weeks vs every 38 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Auth sells 5 one-off in-app purchases. Authenticator asks for nothing beyond the download.

Auth holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Authenticator has 31 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Auth's written reviews are positive against 50% of Authenticator's.

Auth ships an update every 38 months, Authenticator every 5 weeks. The most recent releases landed on October 3, 2026 and October 7, 2026 respectively.
