+
+Now that you have disabled redirects for the SPA, you must login and logout programmatically from your client.
+Below are example JavaScript methods for logging into the `j_security_check` endpoint and logging out of the application by destroying the cookie.
+
+[source,javascript]
+----
+const login = () => {
+    // Create an object to represent the form data
+    const formData = new URLSearchParams();
+    formData.append("j_username", username);
+    formData.append("j_password", password);
+
+    // Make an HTTP POST request using fetch against j_security_check endpoint
+    fetch("j_security_check", {
+        method: "POST",
+        body: formData,
+        headers: {
+            "Content-Type": "application/x-www-form-urlencoded",
+        },
+    })
+    .then((response) => {
+        if (response.status === 200) {
+            // Authentication was successful
+            console.log("Authentication successful");
+        } else {
+            // Authentication failed
+            console.error("Invalid credentials");
+        }
+    })
+    .catch((error) => {
+        console.error(error);
+    });
+};
+----
+
+To logout of the SPA from the client the cookie must be set to `quarkus.http.auth.form.http-only-cookie=false` so you can destroy
+the cookie and possibly redirect back to your main page.
+
+[source,javascript]
+----
+const logout= () => {
+    // delete the credential cookie essentially killing the session
+    const removeCookie = `quarkus-credential=; Max-Age=0;path=/`;
+    document.cookie = removeCookie;
+    
+    // perform post logout actions here such as redirecting back to your login page
+};
+----
+
+To logout of the SPA from the server the cookie can be set to `quarkus.http.auth.form.http-only-cookie=true` and use this example
+code to destroy the cookie.
+
+[source,java]
+----
+@ConfigProperty(name = "quarkus.http.auth.form.cookie-name")
+String cookieName;
+
+@Inject
+CurrentIdentityAssociation identity;
+
+@POST
+public Response logout() {
+    if (identity.getIdentity().isAnonymous()) {
+        throw new UnauthorizedException("Not authenticated");
+    }
+    final NewCookie removeCookie = new NewCookie.Builder(cookieName)
+            .maxAge(0)
+            .expiry(Date.from(Instant.EPOCH))
+            .path("/")
+            .build();
+    return Response.noContent().cookie(removeCookie).build();
+}
