I've been having issues with phone conversations cutting in and out and I dont get all my text messages ever since I got this new phone and I'm tired of it.
Unfortunately I have my 2fa on this phone and I'm posting this to make sure if i do get a new phone that I have the information I need to get the 2fa on the new phone with no issues.
I have my private QR codes for the exchanges and I am not changing my cell phone number..
also, does the google auth work over wifi or does it work through the cell sim card? I wont be throwing the phone out but it will be of no use as far as cell phone calls. would i be able to use the old phone for google auth through wifi?
I just want to verify if I rescan my qr codes for my exchanges that I can get into them once i do this.
if you're using google authenticator, then we're talking about TOTP tokens. it doesn't have anything to do with the sim card or phone number (thank goodness, because those things can be compromised via social engineering).
it doesn't depend on wi-fi. it just depends on proper clock syncing. as long as you don't format your phone or delete your google authenticator app, you should be fine. your token will stay intact and you can keep using your old phone.
but i would say this: when you get your new phone, you should install google authenticator. then remove the old 2fa from your accounts and add a new 2fa token to both your old phone and your new phone. it's really important to have multiple back-ups. also make sure to have a manual copy of your token.
