I’m trying to retrieve the Auth0 userid for my app. I see that it is held in the Idtoken field but this needs to be requested during authentication. How do I do this?  
This is my current authentication request  
Auth0  
.webAuth()  
.scope(“openid offline\_access profile email”)  
.audience(“[https://xxxxxxxxxxxxx](https://xxxxxxxxxxxxx)”)  
.start { result in  
switch result {  
case .failure(let error):  
// Handle the error  
print(“Error: (error)”)  
case .success(let credentials):  
etc.

Hi @elizabeth.wright,

Welcome to the Community!

You should be able to see it as the `sub` claim in the token. Is that claim not being returned?

Hi Dan,

thanks for the reply. Forgive me, I must be missing something obvious. This is my login :

Auth0  
.webAuth()  
.scope(“openid offline\_access profile email”)  
.audience(“[https://xxxxxxxxx.auth0.com/userinfo](https://xxxxxxxxx.auth0.com/userinfo)”)  
.start { result in  
switch result {  
case .failure(let error):  
// Handle the error  
print(“Error: (error)”)  
case .success(let credentials):  
// make the login button a pale grey colour  
print(“Credentials: (credentials)”)

etc.

I get the access token from the credentials, but there’s no sub claim attached? If I try typing credentials.accessToken, there’s no ‘sub’ field available

```
                print("accesstoken = " , credentials.accessToken ?? "")

```

Liz

Are you not recieving the ID token? Or does the ID token not contain the userID?
