Is OTP+ on iPhone now?

Yes. AnyOTP+ arrived on the App Store on November 4, 2026, and NTTGame announced it in its November 5 notice and on its official X and Instagram accounts. You no longer need TestFlight on iPhone: download the app from the App Store and set it up with your OTP ID and activation code.

Its App Store name is AnyOTP+ NttGame: free, and it needs iOS 17 or later. One device holds up to 3 OTP IDs; the app locks with a PIN, a pattern, Face ID or Touch ID and shows a new 6-digit code every 60 seconds.

If the TestFlight version is on your phone, you can install the App Store version without deleting it. NTTGame asks players to use only the official AnyOTP+ app and never give the OTP ID or code to sites or programs that ask for them.

Short answer

AnyOTP+ arrived on the App Store on November 4, 2026, so iPhone users no longer need TestFlight. The app is AnyOTP+ NttGame, free, and needs iOS 17 or later. The "This beta is full" message from the full 10,000-tester TestFlight beta no longer matters.

If NTTGame's TestFlight link showed "This beta is full" on your iPhone, the reason is below, but you don't need that route anymore.

NTTGame opened the iOS version of OTP+ on TestFlight on October 27, 2026, while App Store approval is still running. According to GM Patheoz's official post, Apple limits the beta to 10,000 users and the quota filled fast; no new testers are accepted right now.

TestFlight still says "This beta is full": what now?

  • Skip TestFlight: search the App Store for AnyOTP+ NttGame and install it.
  • Setup needs your OTP ID and activation code; the steps are in the OTP+ setup guide.
  • If your phone runs an iOS older than 17, the App Store version won't install; set OTP+ up on an Android phone instead.

Does the old AnyOTP app work?

Not for the new servers. OTP+ only works with the new codes starting with NT that you get after signing up for OTP+ on the ICS site; the old OTP codes starting with KO don't work in OTP+. Setup steps: How to set up Knight Online OTP+.

Will I miss pre-registration and server selection?

The first pre-registration period ended on October 29, but the 2nd pre-registration and server selection are open until November 12; characters are created on November 10–11. Pre-registration needs phone verification and OTP+ active for Knight Online (NTTGame's pre-registration notice).

FAQ

Do the SMS codes expire?
Yes: per NTTGame, after 10 days. A code you don't use in that time stops working, and you request a new one.
