All you need is to choose a user name and a password. Registration is free, and does not require an email.

• User names are not case-sensitive, but passwords are!
• Passwords need to be 8 chars minimum and contain at least a number.
• Passwords are not permanently stored by kregfile, only secure hashes. Therefore you will not be able to recover your account if you forgot the password!
• You cannot register those default names!
