Verdict
The clearest difference is review sentiment: SundAi at 80% against 2FA Authenticator's 35%. SundAi also leads on iOS requirement (13.0 vs 15.0). 2FA Authenticator's advantage is rating (5.0 vs 4.5) and update cadence (every 6 days vs fortnightly). On price, ratings volume, 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. 2FA Authenticator sells 4 in-app purchases, starting at $4.99 per 7 days and SundAi sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
2FA Authenticator holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 3 and 4 respectively. Written reviews complicate that: 35% of 2FA Authenticator's written reviews are positive against 80% of SundAi's, so the app with the better star average is not the one people write more warmly about.
2FA Authenticator ships an update every 6 days, SundAi fortnightly. The most recent releases landed on September 22, 2026 and August 28, 2026 respectively.
