hey @_cristoforo_ you can email us on rishabh@supertokens.com requesting an email change along with the userId of your account.
You can get the user id of your account by navigating to api.supertokens.com -> inspect element -> applications -> cookies -> sAccessToken -> decode it and send the sub claim. This way, we can be sure that you own the account even if you do not email us from your registered email ID.
