Generate secure passwords and passphrases locally. No network calls - everything is generated on your machine using cryptographically secure random functions.
When to Use
- Generate strong passwords for accounts
- Create memorable passphrases
- Analyze existing password strength
- Build secure password policies
Quick Start
Generate Strong Password
python3 scripts/password-gen.py generate
# Output: 🔐 Password Generated
# Password: K:kx]h--Xo
Generate Passphrase
python3 scripts/password-gen.py passphrase 6
# Output: Password: lambda-window-yellow-nu-mu
Analyze Password
python3 scripts/password-gen.py analyze "MyPassword123!"
Commands
generate [length] [options]
Generate a random password with specified options.
Options:
--no-upper - Exclude uppercase letters--no-lower - Exclude lowercase letters--no-digits - Exclude digits--no-symbols - Exclude symbols--exclude-ambiguous - Exclude ambiguous characters (0,O,l,I)--exclude-similar - Exclude similar characters
Examples:
# Default 16-character password
python3 scripts/password-gen.py generate# 20-character password
python3 scripts/password-gen.py generate 20
# Letters only (no symbols)
python3 scripts/password-gen.py generate 12 --no-symbols
# Numbers and letters only
python3 scripts/password-gen.py generate 16 --no-symbols
# Exclude ambiguous characters
python3 scripts/password-gen.py generate 16 --exclude-ambiguous
# Custom combination
python3 scripts/password-gen.py generate 12 --no-upper --no-symbols
passphrase [word_count] [options]
Generate a memorable passphrase (series of words).
Options:
--separator=char - Word separator (default: "-")
Examples:
# Default 4-word passphrase
python3 scripts/password-gen.py passphrase# 6-word passphrase
python3 scripts/password-gen.py passphrase 6
# Custom separator
python3 scripts/password-gen.py passphrase 5 --separator="_"
analyze
Analyze the strength and composition of a password.
Examples:
python3 scripts/password-gen.py analyze "MyPassword123!"python3 scripts/password-gen.py analyze "weakpass"
list
List available character sets and excluded characters.
python3 scripts/password-gen.py list
Password Strength Levels
- Weak - Short or missing character types
- Medium - Decent length with multiple character types
- Strong - Long with all character types
- Very Strong - Very long with diverse character set
Security Features
- Uses
secrets module for cryptographically secure randomness
- No network requests - all generation is local
- Configurable character sets
- Excludes ambiguous characters option
- Strength analysis and recommendations
Character Sets
- Lowercase letters: a-z (or a-z without l,o if excluding ambiguous)
- Uppercase letters: A-Z (or A-Z without I,O if excluding ambiguous)
- Digits: 0-9 (or 2-9 if excluding ambiguous)
- Symbols: !@#$%^&*()_+-=[]{}|;:,.<>?~
Examples
Basic Usage
# Generate strong password
python3 scripts/password-gen.py generate# Generate 24-character password
python3 scripts/password-gen.py generate 24
For Different Use Cases
# Database password (no ambiguous chars)
python3 scripts/password-gen.py generate 20 --exclude-ambiguous# PIN code (numbers only)
python3 scripts/password-gen.py generate 6 --no-upper --no-lower --no-symbols
# Website password (letters and numbers)
python3 scripts/password-gen.py generate 16 --no-symbols
# Memorable password (passphrase)
python3 scripts/password-gen.py passphrase 5
Analysis Examples
# Analyze existing password
python3 scripts/password-gen.py analyze "MyPassword123!"# Check if password is weak
python3 scripts/password-gen.py analyze "password123"
Tips
- Use at least 12-16 characters for good security
- Include all character types when possible
- Consider passphrases for better memorability
- Avoid using personal information
- Use different passwords for different accounts
- Consider using a password manager
Troubleshooting
"Password too weak" warnings:
- Increase length
- Add more character types
- Use the --exclude-ambiguous
option for clarity
"Command not found":
- Ensure Python 3 is installed
- Check script permissions: chmod +x scripts/password-gen.py`
Security Notes
- Generated passwords are shown in plain text
- Copy passwords immediately after generation
- Don't save passwords in command history
- Use secure methods to store generated passwords
- Consider using a password manager for storage
