# SSO and MFA

The platform offers different options for authentication, including multiple SSO (Single Sign On) options and, on top of any of those, also MFA (Multi Factor Authentication) if/when required.

Access via credentials (standard username+password) powered by third-party or by Meterian is included in all plans. Access via social logins (GoogleWorkspace, Github, etc.), powered by third-party is also included in all plans

Please note that SSO and MFA may incur additional costs.
