I can't manually reset my password
Make sure that you correctly entered all the information on the Restore access page:
If you see an error message that says your email address or phone number is invalid, make sure you entered this data correctly. If you entered them correctly, try to remember any other phone numbers or emails that you might have linked to your account.
If you didn't answer the security question correctly the first time, see if an alternate spelling or other keyboard language works.
Contact Support to restore access
If you didn't manage to restore access yourself, please fill in the Restore Access form.
If possible, fill out the form on the same device (computer, telephone or tablet) that you usually use to log in to Yandex. We also recommend that you fill out the form in the same location where you usually access the internet (for example, from home rather than over public WiFi.)
In the form, enter the personal information that you provided when registering your account or setting up your Yandex.Passport. Enter the information as you remember it, you don't have to remember the exact text. At the final step, you will need to attach a copy of your passport photo page or driver's license. We ask that you photograph yourself next to the document so that nobody can access your account by stealing your document.
