Installation

No external dependencies are required. This script uses only Python standard library modules.

# Clone or download the repository
# Navigate to the securepass directory
cd securepass

# Run the script
python password.py

Run the script and follow the interactive prompts:

python password.py

Main Menu

You'll be presented with two options:

  1. Generate a secure password - Create a new password with custom specifications
  2. Check strength of my password - Analyze an existing password

Generate Password Workflow

  1. Select the password type (1-4)
  2. Enter desired length (4-20 characters)
  3. View your generated password
  4. Optionally get a detailed password report

Check Password Strength Workflow

  1. Enter the password you want to check
  2. Receive a detailed report with recommendations

Example Output

What would you like to do:
1 Generate a secure password
2 Check strength of my password
> 1

Choose password type:
1 Mix of numbers, letters and symbols (Recommended)
2 Numbers only password
3 Letters only password
4 Symbols only password
> 1

Enter your desired length (between 4 and 20): 12
Here is your password: aB3!xK9$mQ2@

Would you like a report for this password? (y/n): y
The password has a length of 12 characters, which meets or exceeds the recommended 8. 
It has 2 uppercase letter(s), 2 lowercase letter(s), 3 number(s), and 3 symbol(s). 
This password has a good mix of character types.

  • Length: Recommends a minimum of 8 characters
  • Character Diversity: Checks for presence of:
    • Uppercase letters
    • Lowercase letters
    • Numbers
    • Symbols

Functions

  • generate_number_only(length) - Generates password with digits only
  • generate_letters_only(length) - Generates password with letters only
  • generate_symbols_only(length) - Generates password with symbols only
  • mix_of_all(length) - Generates password with mix of all character types
  • password_report(password) - Analyzes password strength and returns report

Requirements

  • Python 3.x
  • No external packages required

Best Practices

  • Use "Mix of numbers, letters and symbols" for the strongest passwords
  • Maintain a minimum length of 12 characters for sensitive accounts
