Authenticator is a simple, free, and open source two-factor authentication app. It helps keep your online accounts secure by generating unique one-time passwords, which you use in combination with your other passwords to log into supporting websites. The simple combination of the password in your head and the rotating passwords generated by the app make it much harder for anyone but you to access your accounts. • Easy: Simple setup via QR code, "otpauth://" URL, or manual entry • Secure: All data is stored in encrypted form on the iOS keychain • Compatible: Full support for time-based and counter-based one-time passwords as standardized in RFC 4226 and 6238 • Off the Grid: The app never connects to the internet, and your secret keys never leave your device.

Verdict
The clearest difference is rating: Temp Mail at 4.7 against Authenticator's 3.7. Temp Mail also leads on ratings volume (20K vs 407). Authenticator's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price, update cadence and device support 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. Temp Mail sells 6 in-app purchases, starting at $2.99 per 7 days. Authenticator asks for nothing beyond the download.
Temp Mail holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Temp Mail has 20K ratings behind it against 407, so its average is the more settled of the two. Written reviews complicate that: 68% of Authenticator's written reviews are positive against 47% of Temp Mail's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 22, 2026 and September 28, 2026 respectively.
