+---
+title: Role-based authentication
+---
+
+There are two ways to add role-based authentication (RBAC) to your application, based on the [session strategy](/concepts/session-strategies) you choose. Let's see an example for each of these.
+
+## Getting the role
+
+We are going to start by adding a `profile()` callback to the providers' config to determine the user role:
+
+```ts title="/pages/api/auth/[...nextauth].ts"
+import NextAuth from "next-auth"
+import Google from "next-auth/providers/google"
+
+export default NextAuth({
+  providers: [
+    Google({
+      profile(profile) {
+        return { role: profile.role ?? "user", ... }
+      },
+      ...
+    })  
+  ],
+})
+```
+
+:::tip
+To determine the user's role, you can either add your logic or if your provider assigns roles already, use that instead.
+:::
+
+## Persisting the role
+### With JWT
+
+When you don't have a database configured, the role will be persisted in a cookie, by using the `jwt()` callback. On sign-in, the `role` property is exposed from the `profile` callback on the `user` object. Persist the `user.role` value by assigning it to `token.role`. That's it!
+
+If you also want to use the role on the client, you can expose it via the `session` callback.
+
+```ts title="/pages/api/auth/[...nextauth].ts"
+import NextAuth from "next-auth"
+import Google from "next-auth/providers/google"
+
+export default NextAuth({
+  providers: [
+    Google({
+      profile(profile) {
+        return { role: profile.role ?? "user", ... }
+      },
+      ...
+    })  
+  ],
+  // highlight-start
+  callbacks: {
+    jwt({ token, user }) {
+      if(user) token.role = user.role
+      return token
+    },
+    session({ session, token }) {
+      session.user.role = token.role
+      return session
+    }
+  }
+  // highlight-end
+})
+```
+
+:::info
+With this strategy, if you want to update the role, the user needs to be forced to sign in again.
+:::
+
+### With Database
+
+When you have a database, you can save the user role on the [User model](/reference/adapters/models#user). The below example is showing you how to do this with Prisma, but the idea is the same for all adapters.
+
+First, add a `role` column to the User model.
+
+```ts title="/prisma/schema.prisma"
+model User {
+  id            String    @id @default(cuid())
+  name          String?
+  email         String?   @unique
+  emailVerified DateTime?
+  image         String?
+  role          String?  // New column
+  accounts      Account[]
+  sessions      Session[]
+}
+```
+
+The `profile()` callback's return value is used to create users in the database. That's it! Your newly created users will now have an assigned role.
+
+If you also want to use the role on the client, you can expose it via the `session` callback.
+
+```ts title="/pages/api/auth/[...nextauth].ts"
+import NextAuth from "next-auth"
+import Google from "next-auth/providers/google"
+  // highlight-next-line
+import prisma from "lib/prisma"
+
+export default NextAuth({
+  // highlight-next-line
+  adapter: PrismaAdapter(prisma),
+  providers: [
+    Google({
+      profile(profile) {

+:::info
+It is up to you how you want to manage to update the roles, either through direct database access or building your role update API.
+:::
+
+## Using the role
+
+If you want to use the role in the client, for both cases above, when using the `useSession` hook, `session.user.role` will have the required role if you exposed it via the `session` callback. You can use this to render a different UI for different users.
+
+```ts title="/pages/admin.tsx"
+import { useSession } from "next-auth/react"
+
+export default function Page() {
+  const session = await useSession()
+
+  if (session?.user.role === "admin") {
+    return <p>You are an admin, welcome!</p>
+  }
+
+  return <p>You are not authorized to view this page!</p>
+}
+```
+
+:::tip
+When using Next.js and JWT, you can alternatively also use [Middleware](https://next-auth.js.org/configuration/nextjs#wrap-middleware) to redirect the user based on their role, even before rendering the page.

-title: Role based logins
----
-
-To add role based authentication to your application, you must do three things.
-
-1. Update your database schema
-2. Add the `role` to the session object
-3. Check for `role` in your pages/components
-
-First modify the `user` table and add a `role` column with the type of `String?`.
-
-Below is an example Prisma schema file.
-
-```javascript title="/prisma/schema.prisma"
-model User {
-  id            String    @id @default(cuid())
-  name          String?
-  email         String?   @unique
-  emailVerified DateTime?
-  image         String?
-  role          String?  // New Column
-  accounts      Account[]
-  sessions      Session[]
-}
-
-```
-
-Next, implement a custom session callback in the `[...nextauth].js` file, as shown below.
-
-```javascript title="/pages/api/auth/[...nextauth].js"
-callbacks: {
-  async session({ session, token, user }) {
-    session.user.role = user.role; // Add role value to user object so it is passed along with session
-    return session;
-},
-```
-
-Going forward, when using the `getSession` hook, check that `session.user.role` matches the required role. The example below assumes the role `'admin'` is required.
-
-```javascript title="/pages/admin.js"
-import { getSession } from "next-auth/react"
-
-export default function Page() {
-  const session = await getSession({ req })
-
-  if (session && session.user.role === "admin") {
-    return (
-      <div>
-        <h1>Admin</h1>
-        <p>Welcome to the Admin Portal!</p>
-      </div>
-    )
-  } else {
-    return (
-      <div>
-        <h1>You are not authorized to view this page!</h1>
-      </div>
-    )
-  }
-}
-```
-
-Then it is up to you how you manage your roles, either through direct database access or building your own role update API.

-This is a list of warning output from Auth.js.
+A list of warnings from Auth.js that need your attention.
 
-All warnings indicate things which you should take a look at, but do not inhibit normal operation.
 
----
+## Debug enabled
 
-## Client
+The `debug` option was evaluated to `true`. It adds extra logs in the terminal which is useful in development, but since it can print sensitive information about users, make sure to set this to `false` in production. In Node.js environments, you can for example set `debug: process.env.NODE_ENV !== "production"`. Consult with your runtime/framework on how to set this value correctly.
 
-#### NEXTAUTH_URL
+## CSRF disabled
 
-Environment variable `NEXTAUTH_URL` missing. Please set it in your `.env` file.
-
-:::note
-On [Vercel](https://vercel.com) deployments, we will read the `VERCEL_URL` environment variable, so you won't need to define `NEXTAUTH_URL`.
-:::
-
----
-
-## Server
-
-These warnings are displayed on the terminal.
-
-#### NO_SECRET
-
-In development, we generate a `secret` based on your configuration for convenience. This is volatile and will throw an error in production. [Read more](https://authjs.dev/reference/configuration/auth-config/#secret)
-
-#### TWITTER_OAUTH_2_BETA
-
-Twitter OAuth 2.0 is currently in beta as certain changes might still be necessary. This is not covered by semver. See the docs https://authjs.dev/reference/providers/twitter#oauth-2
-
-#### EXPERIMENTAL_API
-
-Some APIs are still experimental; they may be changed or removed in the future. Use at your own risk.
-
-## Adapter
-
-### ADAPTER_TYPEORM_UPDATING_ENTITIES
-
-This warning occurs when typeorm finds that the provided entities differ from the database entities. By default while not in `production` the typeorm adapter will always synchronize changes made to the entities codefiles.
-
-Disable this warning by setting `synchronize: false` in your typeorm config
-
-Example:
-
-```js title="/pages/api/auth/[...nextauth].js"
-adapter: TypeORMLegacyAdapter({
-  type: 'mysql',
-  username: process.env.DATABASE_USERNAME,
-  password: process.env.DATABASE_PASSWORD,
-  host: process.env.DATABASE_HOST,
-  database: process.env.DATABASE_DB,
-  synchronize: false
-}),
-```
+You were trying to get a CSRF response from Auth.js (eg.: by calling a `/csrf` endpoint), but in this setup, CSRF protection via Auth.js was turned off. This is likely if you are not directly using `@auth/core` but a framework library (like `@auth/sveltekit`) that already has CSRF protection built-in. You likely won't need the CSRF response.

+ * - Add callback URL: http://localhost:3000/api/auth/callback/asgardeo and https://your-domain.com/api/auth/callback/asgardeo
+ * - After registering the application, go to protocol tab.
+ * - Check `code` grant type.
+ * - Add Authorized redirect URLs & Allowed origins fields.
+ * - Make Email, First Name, Photo URL user attributes mandatory from the console.
+ *
+ * Create a `.env` file in the project root add the following entries:
+ *
+ * These values can be collected from the application created.
+ *
+ * ```
+ * ASGARDEO_CLIENT_ID=<Copy client ID from protocol tab here>
+ * ASGARDEO_CLIENT_SECRET=<Copy client from protocol tab here>
+ * ASGARDEO_ISSUER=<Copy the issuer url from the info tab here>

+ * :::info **Disclaimer**
+ *
+ * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).

+ * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
+ * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
