@JammyDodger , I’ve recently registered an account at for a free instance: [이미지] I am unable to register for a free Discourse site id.discourse.com/create-site There, I appear to experience what t/227972 describes, too: OAuth2 SSO 2FA [이미지] [이미지] Most documentation appears to indic…

Moved your post here, because this is a different issue than the Contribute > Bug you posted in originally. Discourse ID is not using OAuth2. It’s functioning, in effect, as an SSO provider, which is different. To configure 2FA, you’d need to do so at the SSO provider, ID. Specifically https://id.…

@jomaxro , thanks. Perhaps, what confused me was that I attempted to set enforce_second_factor to “all”, yet wasn’t able to, because I was informed that “You cannot enforce 2FA if local logins are disabled.” If this isn’t too off-topic, what’s the solution to that?

[이미지] roke_julian_lockhart: You cannot enforce 2FA if local logins are disabled.” If this isn’t too off-topic, what’s the solution to that? That’s a good question … and one I don’t have the answer too. I’ve looped in the team to find someone who does!

To your question, we do not support 2FA with external logins. As the message you saw stated, 2FA cannot be enforced without local logins being enabled. We re…

@jomaxro , does that mean that, with the free trial plan, I cannot modify that preference? Alternatively, can I somehow disconnect Discourse ID?

Want to confirm, are you referring to a free trial, or the free plan?

@jomaxro , apologies. Free plan, I believe: [이미지]

[이미지] jomaxro: We rely on the external login provider (Discourse ID in this case, but this applies to all external providers) to manage 2FA, including enforcement. Question for us: Does the IdP pass along the information of whether or not the user performed MFA to the SP? I’m thinking of th…

[이미지] supermathie: If Discourse ID… or similarly any other IdP (SAML? oAuth2? OIDC?) passes this information along to the SP it would be a piece of information we could potentially use. The standards way to do this is via OIDC. Discourse ID is currently built using OAuth2 only. To support an …
