+Creating a OIDC token from the command line
+-------------------------------------------
+
+.. versionadded:: 7.4
+
+    The ``security:oidc:generate-token`` command was introduced in Symfony 7.4.
+
+The ``security:oidc:generate-token`` command helps you generate JWTs. This is
+particularly useful when developing or testing applications that use OIDC
+authentication.
+
+To generate a token using the default configuration:
+
+.. code-block:: terminal
+
+    # generate a token for the user named "john.doe@example.com"
+    $ php bin/console security:oidc:generate-token john.doe@example.com
+
+    # generate a token when multiple firewall, algorithm or issuer are available
+    $ php bin/console security:oidc:generate-token john.doe@example.com \
+        --firewall="api" \
+        --algorithm="HS256" \
+        --issuer="https://example.com"
+
+.. note::
+
+    The JWK used for signing must have the appropriate `key operation flags`_ set.
+
