Password hardening primarily enables adding security tools and techniques beyond standard password creation and management processes.

There are several techniques for password hardening such as:

• Enforcing users to add special characters or capitalized (Upper Case) alphabets within their password
  

• Restricting users to use their name or easily guessable words or numbers combination in the password
  

• Using multi-factor authentication mechanisms along with the password such as by adding biometric security or smart-card based access besides the password
  

• On-screen scrambled or standard keyboard that requires users to click the characters of the password rather than typing it manually
