> Because currently just a user ID, email, and password hash are stored via supertokens right? Yes. To store other info post sign up, you can override a callback in your node code when initing SuperTokens: https://supertokens.io/docs/emailpassword/common-customizations/signup-form/adding-fields#handle-form-fields-on-successful-sign-up As you can see in the above link, you can override

handleCustomFormFieldsPostSignUp

, which will be called on successful signup. The arguments to this function is the

user

object (

user.id, user.email

). And any extra form fields you may have added to the sign up UI. Using the above, you can store any info associated with your user in a separate table, controlled by your app (and not supertokens).
