Abstract: Most applications increase their security by adding an extra layer to the login process using two-factor authentication (2FA). In Saudi Arabia, One-Time Password (OTP), which is 2FA, is the most common method used as users log in to their accounts. However, some issues have emerged with using OTP as 2FA; these issues from previous research were investigated in the study. Also, the study proposed a new method of account authentication, which is a Memorable Word (MW). MW is the second and short password in which the user enters a certain number of characters instead of the whole password. The study conducted usability testing to compare two 2FA methods, OTP and MW. The study included 60 participants logged into a simulated website using both authentication methods. Then, all participants have to complete the questionnaire. The collected data analyses showed a favourable opinion of the MW method.
