You can change the email you sign in with from your account page on identity.frostweb.studio:

  1. Enter the new email address.
  2. We send a six-digit code to the new address. Enter it on the account page within 15 minutes.
  3. Your sign-in email changes, and the old address gets a notice that it no longer signs in.

If you did not make the change, follow the link in that notice or open a ticket in the Account and sign-in category.

I can no longer reach my old email and cannot sign in

Use the I can't sign in form. The article Recover a hacked account explains how we check that the account is yours.
