# OTP Auth vs 2FA

The clearest difference is ads: OTP Auth at none against 2FA's shown. OTP Auth also leads on update cadence (every 2 weeks vs every 3 months) and ratings volume (463 vs 41). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. OTP Auth sells 1 one-off in-app purchase and 2FA sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for OTP Auth against 4.6 for 2FA. That said, the two scores are not equally well evidenced: OTP Auth has 463 ratings behind it against 41, so its average is the more settled of the two. Written reviews are what separate them: 78% of OTP Auth's written reviews are positive against 83% of 2FA's.

OTP Auth ships an update every 2 weeks, 2FA every 3 months. The most recent releases landed on July 22, 2026 and September 15, 2026 respectively.
