Hi auth0,

I am using [GitHub - auth0/auth0-spa-js: Auth0 authentication for Single Page Applications (SPA) with PKCE](https://github.com/auth0/auth0-spa-js) loginWithRedirect function and passing in a max\_age:0 parameter to re-Authenticate a user as mentioned here [https://auth0.com/docs/login/max-age-reauthentication#limitations-of-prompt-login-parameters](https://auth0.com/docs/login/max-age-reauthentication#limitations-of-prompt-login-parameters)

problem: The id Token i get back using getIdTokenClaims() doesn’t include an auth\_time field that shows the last authentication. I have also tries including prompt=“login”

Thanks

Hey @aly.sabry , I just checked this with the latest spa-js SDK and `getIdTokenClaims()` returned `auth_time`, so I’m guessing there’s something going wrong in your setup.

Some things to check:

1. Open the Network tab in browser’s dev tools before starting the authentication. Now try to login and you will see an `/authorize` request in the list. Click on that and verify that `max_age=0` is being passed as a query parameter there.
2. Get the raw ID token and paste it in [https://jwt.io](https://jwt.io). Check if the parameter is present in the body.

Here’s the code I used btw:

```javascript
await auth0.loginWithRedirect({ max_age: 0 })

```
