Your Yandex ID
Many Yandex services are available only if you have an account. Without one, you can't use such products as Yandex.Mail, Yandex.Disk, and Yandex.Webmaster.
Yandex ID is a single Yandex account. You can use it to access all our products.
If you need to change your password or last name, you just need to update the information in Yandex ID. The changes will automatically apply to all services. Here you can also link a phone number to your Yandex ID and enable login using a one-time password.
