If you setup or request a new password for the renoise.com frontpage/tools section, you will have to enter an email. But for the login, you will need to enter the username instead of the email. This is suboptimal for password managers like the one built-in into Safari: It will already ask you while submitting the password-change-dialogue, if you want to update the password. Then of course the email will be auto-filled in into login. So you you will have to look into your keychain manager to find the new password, if you used Safari’s auto-generate feature.
