The old one will stick around for a bit until the system deletes them. You have to create a new entry and delete the old one. Actually, I think there are security measure by authy to prevent this, but I would still do it just in case.Īnother warning is that if you change your 2FA, you can't edit a 2FA entry in Authy. Let's say someone steals your phone number for example, they won't be able to install a new authy instance. This will transfer the 2FA to the new phone.įor security reasons, make sure you disable the add device after you setup the device and only re-enable it if you want to add device. Let's say your phone gets run over by a car, you can setup a new phone, get a SMS activation message, and then approved the update on the computer. For example, you can setup your desktop client to have authy, which then sync with your phone. If you don't care about getting the original token, you can backup authy by setting up an secondary device. This allow you to import them to apps that support such a format. AndOTP allow exports of 2Fa to a JSON format. When I enter it into AndOTP app first and then Authy. I believe if you enter the secret into Authy, you can't get it back out. However, with 17, you may be better off just doing it manually.Īuthy is actually much worse than Google Authenticator if you want to get the token out. If you are good with python, someone has written a script to do that. Getting the code out of Google Authenticator is not trival. In addition, you have to remember to update the paper whenever you make a change. What if you have a hundred accounts, restoring will be a huge pain. Saving the code to paper only works if you have a few code. in my actual safe) would be an option in case I lose my phone or it breaks for whatever reason, but once I would have authy, that would not be an issue anymore to begin with, as long as I enable the backup function and remember to not change my phone number. I also thought that saving that QR code at home (e.g. while possible, it would be a huge effort for me, and I very much like to prevent that. I do not have a second phone, so how can I actually transfer all my 17 2FA accounts from google authenticator to authy without having to go to each account individually, remove 2FA, generate new 2FA and then scan that one with authy. Second one: well, I cannot export that QR code for kind of very obvious reasons, and a screenshot from the authenticator does not work either, for the exact same reasons. So first question: is that theoretically an option to begin with? Since that is 17 in total I do not want to do it 17 times for each account, so my idea was, I export these in google authenticator as a QR code and scan that QR code with authy, and voila, all my accounts are now in authy. I already use authy (it's the only option for twitch 2FA), but I now want to move all my other accounts I have in google authenticator over to authy. and authy is supposedly a way better option. Their authenticator app and use it to sign in: when (, long story short, I use(d) google authenticator since I can think basically, but I had to help a colleague today and I read a few things and the basic consensus is: "Google authenticator bad". If the user chooses to use TOTP, prompt them to type the TOTP displayed on TOTP MFA is only supported on Firebase Admin Node.js SDK versions 11.6.0 and To enable TOTP as a second factor, use the Admin SDK or call the project If you haven't done so already, install the Owner of the email address by adding a second factor.
