Someone tried to change or delete the phone number for your account.
Complete the operation that you've started on the Phone Numbers page.
This means that someone else got access to your account. Regain control of your account:
To cancel a given operation, click Cancel on the page Phone Numbers .
If you don't cancel the operation within 30 days then changes already made will take effect. You won't be able to restore access to your account since the number you linked to it will be deleted.
Change your security question and answer on the Edit security question/answer page. Choose a question-answer pair that you will be sure to remember and that would not be easy for other people to figure out.
Make sure that there are no other people's addresses on Email addresses page.
We can't know for sure who tried to change or delete your phone number. If you saw which phone number someone attempted to link to your account instead of yours, then you can contact your cellular operator to track down the personal data of the number's owner.
To protect your account, follow our security tips for Yandex.Passport.
Restore access to your account on the Restore access page. If you linked your phone number to your account, then you can use it to change your password.
Fill in the Restore Access form .
