# 2FA vs Auth

The clearest difference is ads: Auth at none against 2FA's shown. Auth also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 83%). 2FA's advantage is update cadence (every 3 months vs every 38 months) and ratings volume (41 vs 4). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. 2FA sells 3 in-app purchases, starting at $3.99 per month and Auth sells 5 one-off in-app purchases. 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: 2FA has 41 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 83% of 2FA's written reviews are positive against 100% of Auth's.

2FA ships an update every 3 months, Auth every 38 months. The most recent releases landed on September 15, 2026 and September 16, 2026 respectively.
