Hi @amek-96,

Welcome to the Auth0 Community!

You can find the user ID created by Auth0 in the token as the sub claim. For example:

{
  "iss": "http://YOUR_DOMAIN/",
  "sub": "auth0|123456", //This is the user's ID
  "aud": "YOUR_CLIENT_ID",
  "exp": 1311281970,
  "iat": 1311280970,
  "name": "Jane Doe",
  "given_name": "Jane",
  "family_name": "Doe",
  "gender": "female",
  "birthdate": "0000-10-31",
  "email": "janedoe@example.com",
  "picture": "http://example.com/janedoe/me.jpg"
}

Otherwise, you can add any claim you would like to the token by using custom claims in an action. Here is an example where the action adds a role to the token. You can easily swap this for an ID:
