Do you support SSO (Single Sign-On)? Do you have support for SAML protocol?

Yes.

SSO is available with the Pro and Enterprise Subscription Levels. You can configure SSO using any of the SAML compatible identity providers (IdP). We support version 2.0 of the SAML protocol. Customers reported successful implementation of the federated authentication with the following identity providers (not limited to):

• Okta
• OneLogin
• F5
• Microsoft Azure Active Directory
• Google Workspaces

Currently, SSO is supported by web apps and Altium Designer. Support in MCAD CoDesigner extensions is expected in the near future. Support is also provided for OAuth for public identity sources—Google, LinkedIn, Facebook.

We also support user and group provisioning/de-provisioning via SCIM protocol, allowing centralized user management.

More documentation can be found at Configuring Sign-in Authentication through the Altium Dashboard

Depending on the IdP, you can enable MFA/2FA for your users. Please read more in “Do you have MFA (Multi-factor authentication)?”
