first take a pic of the qr code in your mobile camera and save the image file in secret area, (like mail) then scan via google authenticator app.
then if you missed the google authenticator you can use this image file for scanning the qr code.
be safe, thank you.
Forget about google authentication, if you lose your device then you are in deep shit!!! I moved to Authy Desktop. It has recovery system - so, if you lose your device then you do not need to manually contact with all the customer services and ask them to remove your 2FA.then if you missed the google authenticator you can use this image file for scanning the qr code.
be safe, thank you.
PS: My list is fairly long...
Authy Desktop is very good, thanks for informing about it. As it got desktop and mobile features also. As you said it got recovery system i have to check it. But it is more easy to use then Google Authenticator. Once i have used google authenticator and their was some problem with my mobile so i have to reinstall all software and google authenticator got deleted but luckily i just have used in one app so was easy to replace it with that site help but like you if i am enrolling for lot of account will be in deep problem.
