I am trying to figure out if Cloudflare access can be used to authenticate any Office365 user? I have got it working for our domain, but my use case is as a customer portal where users come from many other Office365 domains, hence I would like them to be able to use their OWN user account for login?
Looks like the only Microsoft-based login method is AzureAD or SAML, which inherently will only authenticate users that are part of the domain that the connection is set up on.
Cloudflare Access would need to have a login method for microsoft’s
live.com oauth to authenticate other accounts, something that’s not currently provided sadly. You can request the feature bt creating a post in #feedback:prodreq.
