https://community.appian.com/discussions/f/general/21520/log-in-into-appian-with-oauth2-tokenHi there, As far as I know, it is only possible to use a Single Sign On mechanism with Appian using SAML but one of our clients requires to use OAuth2 tokens instead of SAML. Is that possible? Thanks a loten-USTelligent Community 12https://community.appian.com/thread/84300?ContentTypeID=1Tue, 03 Aug 2021 23:02:00 GMTd3a83456-d57b-489c-a84c-4e8267bb592a:57817fab-401a-4559-af66-11ac3fe67039Raghuvaran Nagarajan<p>Though oAuth and SAML both relies on the token or the saml assertion recieved from authorisation server or IDP respectively, oAuth is not an authentication method it is a way of authorising resources. </p> <p>source: <a href="https://www.ubisecure.com/uncategorized/difference-between-saml-and-oauth/">www.ubisecure.com/.../</a></p> <p>Thus Appian provides oAuth only for the webAPIs (as of 21.2) and SAML only for user authentication. </p> <p>So, oAuth tokens cannot be used for user authentication</p><div style="clear:both;"></div>
