# [JWT] Complete auth by phone number

Completes authentication by the user phone number and a confirmation code. The code lifetime is 3 minutes.

This call is used only with the Start auth by phone number call.

The workflow of using this call:
1. The application opens an authentication form so the user can enter their phone number.
2. The user enters their phone number.
3. The application sends the Start auth by phone number request to the Xsolla Login server:
  a. If the parameter send_link is true, after this request, you should send the Get confirmation code request to make SMS contain the confirmation code and link.
  b. If the parameter send_link is false or not passed, the SMS will contain the confirmation code only.
4. The Xsolla Login server sends the SMS and returns the ID of the confirmation code.
5. The application shows a field so the user can fill in the confirmation code.
6. The user enters the received confirmation code or follows the link.
7. The application sends this request to the Xsolla Login server.
8. The user is considered as authorized.
