I have made a website using Next.Js. I used the quickstart and now I have a login and a log out and a user profile page.

When I use the useUser() hook, I get a user object that is the user profile. It provides me with this information

" {  
email: “[email]@hotmail.com”,  
email\_verified: false,  
name: “[email]@hotmail.com”,  
nickname: “[email]”,  
picture: “somepng.png”,  
sid: “some sesssion id”,  
sub: “user id”,  
updated\_at: “time”  
}

I removed identifing marks, but this is what I get.

Now, after they log in, I want to have something like “Hello, [name]” on my main page, but their name is their email. Even when I went into Auth0 dashboard and added username, that isn’t added to the profile.

So, without me manually doing anything, how do I get quick and easy access to the username of the user? Do I have to perform a fetch for all the user data and put it in a useEffect? or is there a way for the profile to have the username?

Hi @chrismcclarin,

Welcome to the Auth0 Community and sorry for the late reply.

You can add the username to the user profile by adding a custom claim to the ID Token with a **Post Login Action** such as :

```auto
exports.onExecutePostLogin = async (event, api) => {
    if (event.authorization) {
      api.idToken.setCustomClaim('username', event.user.username);
   }
}

```

Then, as you have already mentioned you can use the [useUser](https://auth0.github.io/nextjs-auth0/functions/client.useUser.html) function from the @auth0/nextjs-auth0 - v4.0.3 and fetch the user profile, including the username as well.

I hope this helps your case, but others as well.  
Thanks,  
Remus
