How do I change the email address I sign in with?

Sign in at thesisdriven.com/account, click the profile icon at the top right, and select Account. You can change your email address there.

If you only want purchases made under two different addresses to show up in one place, you don't need to change anything. Add the second address instead: see I bought multiple workshops with different email addresses.

If you've already lost access to the old address and can't sign in at all, email hello@thesisdriven.com and we'll move your account across. You keep everything you've bought.
