Hi @Pascaru_Tudor
Currently, the platform supports G Suite, Okta, Azure, ADFS and configuring your own custom SAML provider. This can be an existing solution like Centrify, or a company specific solution. Siemplify supports a wide variety of authentication options provided by the SAML, including 2-factor authentication (2FA).
The Siemplify application uses the default sts of .NET core. Siemplify uses their library for the token authentication against the identity provider; only using the nameID property from the tokens.

Thank you very much @Tomtomfridman .
