# SDK Yandex ID for mobile apps

SDK Yandex ID includes libraries for iOS and Android that allow third-party mobile apps to enable OAuth user authorization via Yandex accounts.

## Authorization using SDK Yandex ID {#web-view}

If the user has Yandex apps installed on their device, they can log in via an account saved in these apps or with a username and password. If there are no Yandex apps installed, webView or their browser can be used to log in.
