Switching Phones/2FA App Question

My Samsung S10 is fading fast. Purchasing a new Android phone.

I recently started using Google Authenticator for much of my 2FA needs. 

As I've never done this before, how do I have websites recognize my new Android phone with newly installed Authenticator app?

Does keeping the same number factor into this?

Don't want to get locked out.

All new to me.

Thanks in advance.

Google Authenticator now allows you to sync it to your Google Account so when you get a new phone you can sync it. I don't recommend that because of potential security risk. You can transfer all your codes to the new phone in one go. See second link and video.

Thanks so much!

You're Welcome

FINALLY getting around to it.

An extremely novice level question. If I use the Google Authenticator 'transfer Accounts' option don't both phones need to be active? If I remember correctly, once I activate the new phone the old phone loses functionality.

I'm not sure but I don't think so. When you select transfer you will get a QR code on the phone you are transferring from. Scan the QR code with the new phone.
