    If you don't already have one, create a user account in the WSO2 Identity Server.

Tip

To provide a better experience for the user, it is recommended to configure an access URL for the application. You can set an access URL from the General tab of the application. (For this sample application, the access URL is https://localhost:3000).

The access URL is used,

  • in the application catalog and discovery flows.
  • to redirect the user back to the application in the following scenarios.
    • if the login page times out
    • after a password reset
    • after the self sign-up verification
  • to re-initiate the login flow if the login flow fails.
