@JammyDodger , I’ve recently registered an account at for a free instance: [imagen] 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 [imagen] [imagen] Most documentation appears…

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 , apologies. Free plan, I believe: [imagen]

[imagen] 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…

[imagen] 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 …
