AI Technical Summary

Problems solved by technology

However, passwords can be easily disseminated or obtained, and this nature of passwords can reduce the level of security
Furthermore, users are required to remember a password to use an electronic device or system, and if the user forgets the password, the user is required to undertake certain password recovery procedures to obtain authentication or otherwise regain access to the device, which is extremely difficult for the user. Said can be cumbersome and has various practical limitations and inconveniences
