nit: Wording suggestion:

"""basic_data.fields[0] corresponds to the password field, which is always
present.
basic_data.fields[1] corresponds to the username field, if there is one.
So, basic_data.size() will be 2 for forms containing both a username and a
password field; and 1 for forms containing only a password field."""
