# Key vs Auth Authenticator

The clearest difference is ads: Auth Authenticator at none against Key's shown. Auth Authenticator also leads on ratings volume (28 vs 2). Key's advantage is update cadence (every 3 days vs every 5 weeks) and iOS requirement (12.0 vs 17.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Key sells 6 in-app purchases, starting at $4.99 per 7 days and Auth Authenticator sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Key against 4.9 for Auth Authenticator. That said, the two scores are not equally well evidenced: Auth Authenticator has 28 ratings behind it against 2, so its average is the more settled of the two.

Key ships an update every 3 days, Auth Authenticator every 5 weeks. Both last shipped on October 24, 2026.
