# Auth vs Authenticator App

The clearest difference is monetization model: Auth at free with in-app purchases against Authenticator App's subscription. Auth also leads on ads (none vs shown) and rating (5.0 vs 4.6). Authenticator App's advantage is update cadence (every 5 weeks vs every 38 months) and ratings volume (84 vs 4). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Auth sells 5 one-off in-app purchases and Authenticator App sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Auth holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Authenticator App has 84 ratings behind it against 4, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Auth ships an update every 38 months, Authenticator App every 5 weeks. The most recent releases landed on September 16, 2026 and September 12, 2026 respectively.
