-thing authentication (2FA) is one of the nice and simplest ways to keep your on line debts at ease. It really works by means of issuing an authentication code for your phone whilst any person attempts to get entry to the account; if that person doesn’t have the code, they (otherwise you) don’t get in. Through using a 2FA app, along with Google Authenticator or Authy, you could prevent any person from getting access to your statistics by means of getting your password. (you can have a code texted to you, but this is taken into consideration a ways much less comfy because of the upward push of so-called SIM hacking.)
there is, of route, a trap. Because 2FA uses a key specific for your smartphone, if you lose or ruin your telephone, you can’t truely reinstall the app in your new cellphone and go on from there. You need to switch the key code for that cellphone as well as the app itself.
different authentication apps take care of this in distinctive methods. In this article, I’m going to have a look at Google Authenticator, such as the perfect way to transfer the app to a brand new smartphone in case you do have get right of entry to to the vintage one, and the way you could prepare for a possible hassle (like a damaged cellphone).

because 2FA uses protection keys that are precise to every piece of hardware, you can’t virtually reinstall Google Authenticator in your new smartphone and use it to log in. As an alternative, you need to switch the keys for your new app.
the perfect approach, specially if you use 2FA with several apps, is to apply the Authenticator app’s committed transfer function to transport your keys from one telephone to the alternative. However, there are assumptions here: first, that you have get entry to to each the old and new smartphone, and second, that you have Android devices. If either of those assumptions doesn’t paintings in your situation, there are different strategies you may use, which we’ll cover subsequent. However first, the clean method.

opportunity approach #2: Take a screenshot of the barcode
One way to create a backup if you lose your cellphone is to take and keep a screenshot of the barcode that is created for each 2FA-secured app. In case you’ve mislaid your backup codes, but you’ve saved a screenshot of the QR barcode which you at first used to create your app’s authentication, you can use that screenshot to set up your credentials on a new telephone.
simply throw the screenshot up for your pc, install Google Authenticator for your new smartphone, and use the plus sign up the app to test the barcode. (you could additionally enter the setup key code if that’s what you stored.) try this for each of your apps, and also you’ll be prepared.
