I have seen that there is a way to authenticate using the second factor of authentication through RSA and DUO.
But I would like to know if there is another way and even better if it has no cost.
I need to show a dashboard which can be accessed from anywhere so as not to have to be creating VPN and permissions for whoever wants to access it.
RSA and Duo are the only MFA mechanisms supported by Splunk today. To ask for additional methods, go to https://ideas.splunk.com and describe your use case.
Many SAML providers can also provide 2FA services. All of the authentication and 2FA is handled by the provider and Splunk doesn't have to know anything about it. From Splunk's point of view, the provider has done whatever it needs to authenticate/authorize and just asserts the identity.
