In the left navigation bar, browse to: Settings and select Advanced
You can change your subdomain from the Clearlogin Subdomain text box at the top of the page.
Note: Your tenant's URL will be changed to "https://yoursubdomain.clearlogin.com". This has bearing on both how you access your tenant, and potentially apps with service provider-based (SP) authentication functionality.
If you must change your subdomain after configuring non-Evolve IP purchased apps that support SP-based authentication, please make sure that you reconfigure any potentially affected apps.
When you are done, click on Save Settings at the bottom of the page
