Hello Gurban Choganov,
Thanks for your question.
Check your device for any installed authenticator apps that might have been used. Some include Google Authenticator, Microsoft Authenticator, Authy, or Duo Mobile.
If you can't find the authenticator used, you need to contact that site's support to help reset your account
