I downloaded this while trying to install Microsoft Authenticator and was pushed into a ₩11,000/week subscription/trial flow. There was no clear cancellation option inside the app. I had to cancel through Apple Subscriptions. Be extremely careful - this is NOT Microsoft Authenticator. **Developer response:** Hello Andyc24_uk, thank you for your feedback. We would like to clarify that this application is an independent authenticator app and is not affiliated with Microsoft. Subscription options and trial details are displayed during the activation process and managed through the App Store subscription system.We understand your concerns regarding clarity and are continuously working to improve the user experience and onboarding flow. Thank you for your feedback. ### 1/5 — Cancel *2025-12-29* Difficult to cancel **Developer response:** Hello #posapp2018, thank you for your feedback. We’re sorry to hear that the cancellation process felt difficult. Subscription management is handled through the App Store settings, and we understand that this can sometimes be confusing. We appreciate your feedback and are continuously working to improve clarity for our users. ### 2/5 — Can stand the Ads *2026-05-14* I thought this was supposed to be a simple Authenticator app so that I can safely log into the system that I use for my business, instead every time I need to use it which is every 30 days, if I remember to check that box, I go to get the code and there’s an ad! I can’t exit out until a little X in the upper left-hand corner appears. Why can’t I bypass it???? This is obstructing the opening of a system that runs my business and it’s irritating! Please fix this and for the love of everything good don’t charge over $2 to have no ads please you’re killing us. Everything is killing us. ### 2/5 — Did not work for me *2025-07-31* The only reason I got the app was because Twitch required it to verify the account I had before changing my phone number. Authy reported that my old number, the one I had for 20 years was incorrect. This was incorrect. Your app is probably great for other folks but did absolutely nothing to assist me. **Developer response:** Hello JeniSquirreliconi, thank you for your feedback. We’re sorry to hear about your experience. Authenticator apps generate verification codes locally on the device, while phone number verification and account recovery are usually managed by the service itself, in this case Twitch. We understand how frustrating it can be when access or verification does not work as expected, and we appreciate you sharing your experience with us. ### 5/5 — Easy to use and fast *2026-06-27* Convenient and safe. Highly recommend using this app! ### 5/5 — Kraken 2FA *2026-01-31* Eddie ### 5/5 — Crypto *2025-11-29* Idk ### 5/5 — Awesome *2025-11-22* Awesome app **Developer response:** Hello Abczsjdbbd, thank you for your feedback! We’re glad to hear you’re enjoying the app. Your support means a lot to our team and motivates us to keep improving the experience. Thank you for being with us! ### 5/5 — RJP *2025-08-26* Ok ### 5/5 — Wow *2025-07-25* Great ## Most praised reviews (1 highest-rated) ### 5/5 — Mil *2025-06-25* Good --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
