2FA google authenticator question

[zend7]

As we all know Samsung has released the latest update for its mobile phones. The problem is I have all accounts that are bitcoin related with 2FA activated in Google Authenticator app. If I update to the latest update will I lose the codes ? I ask this as when I switched to a newer samsung phone when I transferred all my data and apps to the new phone with Samsung magic transfer it transferred everything but the google authenticator was empty, 0 codes.

As far as I know there is something where you are able to create back-up codes for that case. So in case you lose data, change your phone or any other reason, you are able to use those codes to get your data back.

Thanks that isn't my case. I didn't want to risk when I migrate to new phone so I manually disabled every 2FA I had enabled in the old phone and then reenabled them in the new phone. The problem now is I want to update the phone and not move from a phone to another but I don't know if my credentials will be lost or not over this update. I guess I am forced to not update the phone or manually disable again and reenable soon after the update.

All you need is the code that they tell you to write down when you first set up 2FA. This is only an if anyways because I don't see why an update on your OS would get rid of pertinent information like that. Do your updates usually delete app data??

Side note: if you disable 2FA I'd put all of your bitcoins on a paper wallet for now. That's extremely dangerous.

If the site will not give you the backup key to your 2FA, you could temporarily disable it, re-enable and make sure you have the backup code written down.
Its probably a good idea to do this before you update your phone.
The update shouldn't do anything to your apps (hopefully)
but if you get locked out of your accounts it would be bad, obviously.
I've been waiting 3 weeks with no response from Coinbase support because of losing access to my 2FA.

Usually updates in my old phone didn't do this but when I transferred all my data to my new phone as I said it did this. So I had to disable and re enable manually everything. I guess I have to go this route now too if I don't want losing a considerable part of my bitcoin which I have worked 1 or more year.
