title: Is "scope" a standard claim?
body: <p>Is there any standard <code>scope</code> claim in OpenID Connect, JWT or OAuth?</p>
  <p>In the <a href="https://identityserver4.readthedocs.io/en/latest/topics/resources.html#authorization-based-on-scopes" rel="noreferrer">IdentityServer 4 documentation</a>, the there is a &quot;scope&quot; which is a space-separated string.</p>
  <pre class="lang-json prettyprint-override"><code>{
    &quot;client_id&quot;: &quot;mobile_app&quot;,
    &quot;sub&quot;: &quot;123&quot;,
    &quot;scope&quot;: &quot;read write delete&quot;
  }
  </code></pre>
  <p>But from my IdentityServer 4 instance, I get a &quot;scope&quot; claim in the access token which is a array of strings.</p>
  <pre class="lang-json prettyprint-override"><code>{
    // ...
    &quot;client_id&quot;: &quot;mobile_app&quot;,
    &quot;sub&quot;: &quot;123&quot;,
    &quot;scope&quot;: [ &quot;openid&quot;, &quot;profile&quot;, &quot;email&quot;, &quot;offline_access&quot; ],
    &quot;amr&quot;: [ &quot;pwd&quot; ]
  }
  </code></pre>
  <p>In the <a href="https://openid.net/specs/openid-connect-core-1_0.html#ClaimsContents" rel="noreferrer">OpenID Connect Core 1.0</a> specification, I do not see &quot;scope&quot; listed as a claim.
  In the <a href="https://datatracker.ietf.org/doc/html/rfc7519#section-4.1" rel="noreferrer">RFC 7519</a> JSON Web Token (JWT) specification, I do not see &quot;scope&quot; listed as a claim.</p>
