QMetry Supports SAML Authentication. Security Assertion Markup Language (SAML) is an XML-based standard for exchanging authentication and authorization data between an identity provider and a service provider. SAML is used for single sign-on to eliminate application wise passwords. QMetry Admin can integrate SAML for authentication to allow QMetry Users to login using single sign on. Currently, QMetry supports only Okta as an SAML provider.
