Users updating their Apple devices to iOS 15 may experience duplicate or total loss of existing keys inside their Google Authenticator. Based on the various scenarios, Bybit would like to advise the following:
1) If users have NOT performed the iOS 15 update
We highly recommend our traders postpone any updates till further notice. However, if you still would like to proceed with it, kindly ensure that you have either kept a secured backup of your Recovery Key Phrase (RKP) or manually transfer your Google Authenticator codes into another device first before updating to iOS15.
2) If users HAVE performed the iOS 15 update
In the event that an upgrade has been performed, you may encounter duplicates inside your Google Authenticator app. Kindly be advised to refrain from deleting any duplicate keys to avoid issues when entering your Google 2FA codes into Bybit.
