FAQ

• What type of SSO does Affinity support?
  Affinity currently supports SAML 2.0 or OpenID Connect as an authentication method. Custom SSO integrations are only available for users who use Microsoft Exchange or Office365 as an email provider.
  
  
• Does Affinity support Service Provider initiated(Web Browser) SSO?
  Yes.
  
  
• What claims does Affinity require in the callback request?
  We only require the user’s email address.
  
  
• What’s the most secure hash algorithm that Affinity accepts?
  SHA256.
  
  
• Does Affinity require token encryption?
  We do not require token encryption. We won’t be making any additional requests after initial authentication so this shouldn’t be necessary.
  
  
• Does Affinity require Relaying Party-Initiated(RP) Sign-On?
  No. Since the Affinity application is a cloud application that is accessible over the public internet, most of our users access the application directly by our URL on their browser.
  
  
• Does Affinity require Relay State support?
  No.
  
  
• Have you enabled your site to automatically update your federated metadata information?
  Yes. We periodically refresh the metadata stored for your organization from your metadata URL. For example, if your public key changes, Affinity will detect the change and continue to valid signatures accordingly.
