# All vs Authenticator App

The clearest difference is rating: All at 4.8 against Authenticator App's 3.0. All also leads on ratings volume (17 vs 2). Authenticator App's advantage is ads (none vs shown) and update cadence (every 2 days vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. All sells 3 in-app purchases, starting at $1.99 per month and Authenticator App sells 11 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

All holds the better App Store score, 4.8 against 3.0. That said, the two scores are not equally well evidenced: All has 17 ratings behind it against 2, so its average is the more settled of the two.

All ships an update every 3 weeks, Authenticator App every 2 days. The most recent releases landed on October 6, 2026 and October 7, 2026 respectively.
