If you properly configure the security of mail / wallets / exchanges, you must install two-factor protection (Google Authenticator). During the configuration process, you need to scan the QR code so that the Authenticator application starts to generate unique 6-digit codes. When you scanned, you added the key to the application, and everything seems fine.

BUT here there is a moment - and what if your phone / tablet breaks, or you lose it, how on the new device to restore the codes of Google Authenticator?

1. You can make screenshots of QR codes when attaching two-factor codes, and hide printouts in the storage room (why not)

2. Use the online version of Google Authenticator, but if you break the laptop / PC, everything will go into oblivion (a bad option)

3. After losing the device, make a million tickets on all exchanges / wallets / mails, and spend months with technical support (very long, and not always efficiently)

4. And you can use special official programs that will help you decrypt the QR code and show you a unique secret key (a set of numbers and letters) that you can enter on the new device, thereby restoring access to Google Authenticator codes

For Android device owners

Application: QR Droid
Play Market: https://play.google.com/store/apps/details?id=la.droid.qr&hl=en
How to use: start, scan the QR code when connecting two-factor protection. Next, you will see a text consisting of numbers and letters,
for example secret = twwolj564uf7x4se6ft7t2hhfjh1c33v & issuer = Google

When configuring Gmail mail - everything in the text after "secret =" and up to the "&" sign, and there is your secret key.
When configuring the rest of the services: everything in the text after "secret =" is your secret key.

For Apple Owners

Application: QR-Code Reader
App Store: https://goo.gl/5VuLxh
How to use: start, scan the QR code when connecting two-factor protection. Next, you will see a text consisting of numbers and letters,
for example secret = twwolj564uf7x4se6ft7t2hhfjh1c33v & issuer = Google

When configuring Gmail mail - everything in the text after "secret =" and up to the "&" sign, and there is your secret key.
When configuring the rest of the services: everything in the text after "secret =" is your secret key.

_______________________________________

Keep your keys separate from passwords, always have multiple backups, both on physical media and in print. In this case, in case of force majeure (loss of your electronic equipment), you can quickly restore access to your accounts on different services.
