What is the weakest form of authentication?

The weakest form of authentication is single-factor authentication (SFA), typically a simple username and password or PIN, because it relies on just one piece of information that can be easily guessed, phished, or brute-forced, making it vulnerable to compromise and unauthorized access. Knowledge-based questions are also very weak as answers are often publicly available or easily guessable, falling under the "something you know" factor.
