Cloudflare Access is currently able to act as an SAML intermediary for SaaS applications. OIDC is a pretty popular alternative to SAML and has been implemented in a lot of apps. It is also a lot easier to set up.
It would be nice if Cloudflare Access can support being an OIDC endpoint, in addition to supporting SAML. This would also add support for SaaS applications that do not support SAML, but only OIDC.
