# Authenticator™ App vs Duo Auty 2FA

The clearest difference is rating: Duo Auty 2FA at 5.0 against Authenticator™ App's 4.1. Authenticator™ App's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (every 4 weeks vs every 8 months).

Both are free to download. Authenticator™ App sells 3 in-app purchases, starting at $7.99 per 7 days and Duo Auty 2FA sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Duo Auty 2FA holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Authenticator™ App has 445 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 16% of Authenticator™ App's written reviews are positive against 0% of Duo Auty 2FA's, so the app with the better star average is not the one people write more warmly about.
