You can programmatically generate a username and allow users to log in with their email only.

You need to:

1. remove the input from the registration form

2. hook into the registration action and programmatically generate a unique username (probably based off their email)

3. set_input('username', $username);

@Flying dutchman : you can skip username and use email instead. Generate a unique and random username in the background when the form is submitted but before processing (as Matt explained).

@blogbids : use profile_manager plugin.

You helped me make a simple plugin to plugin profile_manager I understand, for example facebook plugin from registration, simply as that. Thank!!
