We've worked hard to allow you to use a single account for all systems that you might use with Proxeuse. Your billing management, DNS zone management, API access, hosting panels will all be connected to the central authentication system on auth.proxeuse.com. For reactivating your account please read this article.
You'll be able to see all available applications for your user account in the overview on that portal. You should be able to log in to any of the listed applications with a single button press.
Using the SSO (Single Sign On) functionality enhances your online safety and comfort with using services provided by Proxeuse or their partners. For example, in the auth.proxeuse.com you'll be able to create passkeys for passwordless authentication.
Please note that there is currently no support for logging into Plesk using the centralized authentication. You'll need to use the seperate username/password combination shown in the billing portal. In the future there will be a button which automatically logs you in and redirects you to Plesk.
