Examples

1. Validating a Weak Password

Background
A user is signing up for a new service and enters 'abc123' as their password.
Problem
The password lacks uppercase letters and special characters, making it weak.
How to Use
Enter 'abc123' in the password field with the default minimum length of 8.
Outcome
The tool returns that the password is weak because it is too short and missing uppercase and special characters.

2. Custom Length Validation

Security Administrator
Background
An admin needs to enforce a 12-character minimum for all employee passwords.
Problem
Check if 'MySecurePass!' meets the custom length requirement.
How to Use
Enter 'MySecurePass!' and set the minimum length to 12.
Example Config
minLength: 12
Outcome
The password is validated as strong since it meets all criteria, including the 12-character minimum.
