title: How do I disable sign up in an Azure API Management developer portal?
body: <p>My goal is a publicly available Azure API Management Developer Portal where the users can sign in if they want, but the sign up functionality has been disabled - you have to be invited by us to get a user.</p>
  
  <p>I've enabled the Management API and use the <a href="https://docs.microsoft.com/en-us/rest/api/apimanagement/2019-12-01/signupsettings/update#code-try-0" rel="nofollow noreferrer">Sign Up settings page</a> to PATCH with this body. This returns a 204 No Content, so the call seems to be correct.</p>
  
  <pre><code>{
    "properties": {
      "enabled": false
    }
  }
  </code></pre>
  
  <p>I would have expected to that sign up was removed and disabled from the portal, but it's not. What I see instead is that 'Username and Password' has been removed from Identities in the Azure Portal. Users can still sign in and sign up even though this is removed, which I find weird.</p>
  
  <p>Has anybody experience the same? Any suggestions to what I could try?</p>
