However, passwords can be easily disseminated or obtained, and this nature of passwords reduces the level of security

Furthermore, the user is required to remember a password to use an electronic device or system, and if the user forgets the password, the user is required to undergo certain password recovery procedures to gain authentication or otherwise regain access to the device, which are of great importance to cumbersome for the user and has various practical limitations and inconveniences
