# Verification at login

## If you log in from other device {#different-device}

When you log in from a new or someone else's device, Yandex may consider the login attempt suspicious. We will ask you to go through one of the additional checks:

- We can send you an SMS or call the [main phone number](https://www.yandex.com/support/id/en/authorization/phone.md) linked to your Yandex ID. Enter the code from the SMS or the last four digits of the incoming phone number.
- We can ask you to answer your security question.
- We can email you a confirmation code to your [alternate email address](https://www.yandex.com/support/id/en/authorization/email.md).

Additional checks are selected by Yandex algorithms to ensure maximum account security.

If the main number is currently unavailable, [contact support](https://forms.yandex.ru/surveys/1741) or try to [restore access on your own](https://passport.yandex.com/restoration/form).


## Login verification by phone number {#phone-confirm}

If you enabled login verification by phone number in your account settings, we will send an SMS or call the [main number](https://www.yandex.com/support/id/en/authorization/phone.md) linked to your Yandex ID when trying to log in. Enter the code from the SMS or the last four digits of the incoming phone number.

## If you log in from an unusual place {#different-place}

When you log in from an unusual location or your actions resemble those of a robot, Yandex may consider the login attempt suspicious. We will ask you to go through one of the additional checks:

- We can send you an SMS or call the [main phone number](https://www.yandex.com/support/id/en/authorization/phone.md) linked to your Yandex ID. Enter the code from the SMS or the last four digits of the incoming phone number.
- We can ask you to answer your security question.
- We can email you a confirmation code to your [alternate email address](https://www.yandex.com/support/id/en/authorization/email.md).

Additional checks are selected by Yandex algorithms to ensure maximum account security. Hackers who don't have access to your personal data won't be able to log in to your account, and you'll receive a [notification](https://www.yandex.com/support/id/en/messages.md#suspicious-login-attempt) from Yandex every time there's a suspicious login attempt.

If you can't restore access to your account, contact support.
