This applies for all data. In particular, for both locally stored data as well as data stored in the iCloud Drive (when iCloud Sync is enabled). The password for those files never leaves your device such that noone but you can read your data. OTP Auth does not collect information about you or send them anywhere. You won't be asked to allow access to your contacts or your location. And most important: OTP Auth does not connect to the internet and will not send your accounts to someone else! (Unless you enable iCloud sync where an AES-256 encrypted copy of your accounts is stored in your iCloud Drive. The password for that copy will never leave your phone.) Follow me on Twitter: @otpauth

Verdict
The clearest difference is rating: OTP Auth at 4.6 against iPIN2's 1.0. OTP Auth also leads on ratings volume (463 vs 5) and update cadence (every 2 weeks vs every 2 months). On price, review sentiment, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. OTP Auth sells 1 one-off in-app purchase and iPIN2 sells 1 in-app purchase, starting at $5.99 per year. Whichever you choose, the download price is not the number that matters.
OTP Auth holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: OTP Auth has 463 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 78% of OTP Auth's written reviews are positive against 84% of iPIN2's, so the app with the better star average is not the one people write more warmly about.
OTP Auth ships an update every 2 weeks, iPIN2 every 2 months. The most recent releases landed on July 22, 2026 and September 22, 2026 respectively.
