I am very new to SAML and currently doing research on whether SAML is the right solution for me.
All the SAML examples that I can find work on the email domain. I wonder if it is possible to build a service provider and identity provider based on a phone number.
- if I go to https://www.atlassian.com/ login form and input my email
firstname.lastname@example.org, Atlassian will ask for my password.
- if I instead enter
company.comis configured for Google SSO, Atlassian will redirect me to the Google login form. By using email domain, Atlassian is able to redirect to different Identity Providers, therefore maintaining a multi-tenancy SaaS solution.
Is it possible to implement SAML SSO based on a phone number or other attributes? What are the other commonly used attributes?
