Yandex messages - Yandex ID. Help
https://yandex.com/support/id/messages.htmlYandex sends this message when a new app password is created for your Yandex ID (this can only be done in the Programs with account access block on the Access management page). If you didn't create a password for the app mentioned in the email, then it may mean that a hacker who got access to your account created it.
