Enable two-factor authentication
You can activate two-factor authentication in Yandex.Passport. You will need the Yandex.Key app, which you can install on a mobile device running on iOS or Android. You can't use devices that don't support this app (like Amazon Kindle Fire).
After you enable two-factor authentication:
For third-party mobile apps, computer programs, and mail importers, you must use individual app passwords.
Your Account access restoration process will change.
Setting up 2FA takes a few steps Two-factor authentication will only activate after you click Complete setup.
Step 1. Confirm your phone number
Go to Yandex.Passport, find the Passwords and authorization section, and click Set up two-factor authorization.
If you already linked your phone number to your account, the browser will display this number and ask if you want to confirm it or change it. If your current phone number is not linked to your account, you must link it, or else you won't be able to restore access to your account on your own.
To link or confirm a number, request that a code be sent via SMS and then enter it into the form. Once you've entered the code correctly, click Confirm to proceed to the next step.
Step 2. Create a PIN code
Think of a four-digit PIN code and enter it for two-factor authentication.
Click Create to confirm your PIN code.
Step 3. Set up Yandex.Key
In Yandex.Key, tap the Add account button. Yandex.Key will turn on your camera in order to scan the QR-code displayed in the browser.
If the QR-code cannot be read, click Show secret key in the browser, or on Add it manually in the app. Instead of the QR-code, the browser will display a sequence of characters that must be entered into the app.
When it recognizes your account, your device will request the PIN code you created during step two.
Step 4. Check your one-time password
To make sure that everything is set up correctly, you need to enter a one-time password at the last step. Two-factor authentication will be enabled only after this step is completed.
Enter the PIN code you created during Step 2 into Yandex.Key. The app will display your one-time password. Enter it next to Enable and click the button. In some cases, you'll be asked to enter the password that you used before enabling 2FA.
If you entered the correct password, 2FA will be enabled and your Yandex.Passport page will open.
