Change my email address/password
Be sure you are logged in to your iFixit account.
Click the small icon in the top right corner there will be a drop down menu
EUSTORE Version says - Edit Profile
iFixit.com Version says - View Profile
From View Profile you select Edit in the top right corner
From there you can change your name/profile name/email address/password
If your profile does not have the options to change your password then you are likely signed in with O-Authorization which means that you use Google or Facebook to login to your account. If this is the case please let us know and we can remove the authorization and get you on your way to be able to edit your password.
For all other abnormalities please reach out to customer service.
