Why can I only use my company user account?

Single Sign-On (SSO) enables quick authentication of company e-mails that are under the same work domain. This guarantees that company information is protected and company users don’t need to create multiple logins for different platforms, which could create potential security breaches.

As employees and contractors, your personal e-mail should be the one associated with your account to guarantee that you can always have access to your personal information, regardless if you changed or left a company.
