+==== Accessing the H2 Console in a Secured Application
+H2 Console uses frames and, as it is intended for development only, does not implement CSRF protection measures.
+If your application uses Spring Security, you need to configure it to
+
+* disable CSRF protection for requests against the console,
+* set the header `X-Frame-Options` to `SAMEORIGIN` on responses from the console.
+
+More information on {spring-security-docs}#csrf[CSRF] and the header {spring-security-docs}#headers-frame-options[X-Frame-Options] can be found in the Spring Security Reference Guide.
+
+In simple setups, a `SecurityFilterChain` like the following can be used:
+
+include::code:DevProfileSecurityConfiguration[]
+
+WARNING: The H2 console is only intended for use during development.
+In production, disabling CSRF protection or allowing frames for a website may create severe security risks.
+
+TIP: `PathRequest.toH2Console()` returns the correct request matcher also when the console's path has been customized.
