  2. From the screen that opens, continue to log in to the application using either of the following methods:
    • Using Single Sign-On (SSO)
      Note: You can use SSO to log in to the application only if your IT administrator has configured Single Sign-On (SSO) for your Mitel account.
      1. Click Single Sign On. You will be redirected to your SSO provider to sign in to your account.
      2. Enter your credentials in the fields provided, and click Sign in to log in to the application.
