Challenges with Password based Authentication:

1. Easy passwords can be cracked

The end users behavior such as choosing passwords that are easy to remember introduces the majority of the password weaknesses. For a hacker, these passwords can be easily guessed through brute force attack. Mainly these passwords are the words or phrases related to the end user day to day life itself.

2. Random passwords can’t be remembered

A random password should not have a content, context, and should not be familiar this leads to an end user to forget the password easily. The only way to learn it is by using it over and over again. Since it is not a practical solution the user ignores using pseudo random numbers.

3. Remembering Multiple Passwords

The more the passwords a person has to remember, the greater is the chance for forgetting any specific password. The usage of multiple passwords also increases the chance of interference among similar passwords. This affects adversely to those systems which are less frequently used.

4. Problems with passwords that needs to be continuously
