Hacking without credentials
Summary: PortSwigger Research notes that web applications commonly expose unauthenticated functionality, with peripheral functions supporting authentication logic - user registration, password change, and account recovery - typically the most promising initial targets. In the narrower case where the web root returns only a simple login form with no other functions or links, the text states that guessing a username and password is not the only option, and that if the listed attacks fail, the login mechanism is more robust than most.
What you should know: The registration, password-change, and account-recovery flows built around your login are named as the most promising way in for an attacker holding no credentials at all - the login form itself is rarely the weakest point.
