Lance Tallman from this post

https://learn.microsoft.com/en-us/answers/questions/1611622/external-identity-user-flows-disabling-sign-up-in

references the following link:

https://learn.microsoft.com/en-us/entra/external-id/customers/how-to-user-flow-sign-up-sign-in-customers#disable-sign-up-in-a-sign-up-and-sign-in-user-flow

but that section of the KB has been removed from the published article

You can find what he is referencing here in the waybackmachine

Anupam Bishui also references the documentation

So I contacted support and Taveesack Reed, Support Engineer, went through the documentation and tested to see if this redacted documentation still works. Taveeksack confirmed that it does still work.

Also, I will quote Taveesack verbatim:

-----------------------------------

Regarding the public documentation for this feature, the escalation team has clarified that there are currently no plans to deprecate the existing workaround or setting. Furthermore, a hotfix was issued recently in December of last year to address a bug wherein disabling the Sign-Up flow would inadvertently present additional sign-in options, which is not the intended behavior, as noted in this accompanying documentation, the relevant information is towards the bottom. https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Flearn.microsoft.com%2Fen-us%2Fanswers%2Fquestions%2F2123394%2Fentra-external-id-additional-sign-in-options-after&data=05%7C02%7Cjoseph.vichi%40biberk.com%7C038a0808378a44e76ad608dd6596acc4%7Cd21ebc5494dd4169ba8cb68177a7918b%7C0%7C0%7C638778420050808478%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=ouPgXQjtV7dgGd9RzuKaxsk2MaYO9jkuDlhk4J0EYBU%3D&reserved=0

Additionally, we were unable to obtain any additional information about why the "disable sign up flow" document is not accessible online.

Please restore this documentation.
