MEXC Global has introduced a security measure called two-factor authentication, and most users should have introduced it. However, if you are using Google Authenticator, you may lose your authentication code if you lose your mobile phone. What should I do in such a case?
Two-factor authentication setting method
The following article explains how to set up two-factor authentication when opening an account. It is also possible to set two steps after opening an account. Please refer to the following articles.
Backup of Google Authenticator
Any person should be able to change smartphone models and break down. Modern smartphones have a lifespan of two to three years, so most people should replace them. At that time, there will always be people who lose the authentication key of Google Authenticator. Therefore, we strongly recommend that you make a backup in advance.
Backup method
Google’s authenticator app saves the information required for one-time passwords in your smartphone’s storage. If you change the model, you will definitely need to transfer the data. Google’s Authenticator performs data migration using the “export/import” procedure. Even if you say export, you don’t need to save data. Please start Google Authenticator first. Since there is a “…” mark on the upper right of the screen, select “Data migration” from there. Then select “Data Export”.
After selecting data export, a QR code will appear. By saving this code as an image in advance or scanning it, another model will be able to restore the current Google Authenticator data. In other words, if you can display this QR code, you can restore it even if you change to another model without problems.
If you want to read the QR code from your new smartphone, first install Google Authenticator.
Just launch the app and read the QR code to enable recovery.
Create backup code
There is a backup code creation method for restoring Google Authenticator. If your smartphone breaks and you can’t use the authentication app, of course you can’t use Google Authenticator. In this case, if you generate a backup code in advance, you can restore it. Be sure to keep the data offline or on paper. First, access your Google account and select “Security” from the side menu.
Select 2-Step Verification. You will be asked to enter your Google account password, so enter it and press “Next”. 2-step verification is not required. password only. Default to the QR code style “Authenticator App”.
Once set, you will be able to create backup codes. The generated code can now be used to restore the Google Authenticator. Never forget your code. With this, you can recover your smartphone even if it is lost or destroyed.
If you don’t have a backup of Google Authenticator
If you don’t have any backups of your Google Authenticator, and your phone is lost and you don’t have any information, you’re stuck. In this case, since there is no recovery method, you will not be able to log in to MEXC. But it’s not that there’s nothing you can do. Please contact the MEXC support center. The MEXC support center will respond without logging in. Please refer to the article below.
