when registering using auth0-js v9 new WebAuth in an incogntio window using google chrome, I am met with the login\_required error.

The registration is fine when in a non incognito tab so the audience, clientId and domain creds passed below we can presume correct.

```auto
new WebAuth({
      clientID,
      domain,
      audience,
      responseType: 'token id_token',
      redirectUri,
      scope: 'openid profile offline_access'
})

```

```auto
[WebAuth].authorize(
     {
        email,
        connection,
        authorizeCallType: "registration",
        redirectUri,
        state,
      },

```

I have also tried the suggested refresh token rotation and updated the following settings;  
The api access settings has Allow Offline Access toggled on and the application has its Refresh Token Rotation toggled on with a reuse interval of 30003

With these two enabled and offline\_access added to the scope (see above), I no longer get login\_required; however I get a missing\_refresh\_token error

How can I allow registration within an incognito tab?

Hi @a3h16,

Refresh tokens aren’t supported in Auth0.js, so that approach wont help here.

Could you please DM me a HAR file of the request? I’d like to see the call that is being made and the response.
