Invited single sign-on (SSO) connects your customer to your application using an email invitation.
Invited SSO is for your customers who already have an identity provider (IdP) set up. You send them an email invitation containing the connection information for your application. Included in your email is a link for the customer to either register a new PingOne for Enterprise Invited SSO account or sign on to their existing account. They then add the connection to your application.
When the customer receives the email and clicks the link in the message, they're directed to the PingOne SSO for SaaS Apps portal to either register a new SSO account or add the connection to your application to an existing account.
