Investigating what´s new on IOS 15.0.2 Update Apple's also included a built-in authenticator that's similar to Google Authenticator. This will let you generate verification codes for enhanced sign-in security under your Passwords.

At this moment that built-in feature cannot be disabled and Google Authenticator & Microsoft Authenticator are not compatible with the format to load our URL on IOS 15.0.X

From now, Google Authenticator & Microsoft Authenticator are no longer supported in IOS 15.0.X until Apple fixes that bug and allows us to disable that option and permit the use of Google Authenticator again instead of his own app.

Is a fix from Apple, not Mi-Token, but I´ll still investigate a way to skip that problem.
