Someone has set up importing email from my Yandex mailbox to another service. What do I do?

Step 1. Prohibit another service from accessing your mailbox

1. Open your account settings.
2. Under Logins and devices, click Devices, services, and applications.

   
3. Go to Other applications and services and find the mail service you definitely didn't use for importing emails from Yandex. Click to the left of it to see the details. Then click Delete.

   
4. Enter your password to confirm the operation. If you have two-factor authentication enabled, use the one-time password generated by the Yandex.Key app

Step 2. Check your computer for viruses and change your password
