Password-based Authentication in Computer Security: Why is it still there?

Abstract

Amongst today’s methods of authentication, the old-fashioned technique which requires a username
and password remains the prevailing measure of securing computers, email accounts, or online transactions.
Besides the threats people are often exposed to if they don’t change their passwords regularly, there is always a
risk that passwords wipe out from human memory over a longer period of time. This research is exploring the
flaws of the dominating username-password security measure, and focusing on the alternative authentication
and authorization techniques. Furthermore, the classification of password usage is given and suitable
authentication methods are suggested.
