How can I set up Single Sign-On (SSO)?

Account Owner Setup:

As an Account Owner (Admin rights are insufficient), go to Account > Access > Single Sign-On (SSO), to setup SSO: 

In order to have a functional, Single Sign-On configuration, two elements are required in the settings page:

Identity Provider Sign-In URL: Supplied by the identity provider. Verifies members when they enter their work credentials. It's the URL the end-user is redirected to, to confirm his/her credentials on the IDP side.

Certificate: This security certificate is supplied by the identity provider.
Reversely, these are pieces of information from Onfido needed to configure the Identity Provider:

- Audience: https://onfido.com
- Recipient: https://onfido.com/users/auth/saml/callback
- ACS Consumer URL: https://onfido.com/users/auth/saml/callback
- ACS Consumer URL validator: ^https:\/\/onfido\.com\/users\/auth\/saml\/callback$
- Single Logout URL: https://onfido.com/users/auth/saml/slo
