Your Retarus implementation manager will assist you with setting up your account and provide you with the company name and tenant name created for your account. The web address you need to access the Retarus Enterprise Fax Portal will also be shared.

Signing in with SSO
If SSO is configured for your tenant, clicking Continue to Sign in after selecting your tenant redirects you to your organization’s identity provider (for example, Microsoft Entra ID). Sign in there with your organization credentials. Once your identity provider authenticates you, you are returned to the Fax Portal main screen.
Session timeout
Your session stays active while you use the portal within a 60‑minute period. If you do not interact with the portal for 60 minutes, the system automatically signs you out. You must then sign in again to continue your work.
