I guess that would work. Maybe it is an option to do some sort of query in the background (AJAX?) when the username is filled in, so you can dynamically add extra inputs to your login form.<\/p>\n

However, this has one potential issue: everybody that knows someone ‘s username can find out what authentication is required. If that is not wat you want, maybe just ask for a username + password to login to a reduced privelege mode. Then, as you suggested in your question, this reduced privelege mode may require extra credentials to continue to the more secure environment.<\/p>\n

You could even make it so the reduced privelege mode will grant access to some of the features, while others require extra authentication (for example: posting a mesage would require basic auth, changing passwords might require all four).<\/p>\n<\/p><\/div>\n
