Password Generator

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

bash

python3 scripts/password-gen.py generate
# Output: 🔐 Password Generated
#         Password: K:kx]h--Xo<RKwKp
#         Length: 16
#         Strength: Strong

Generate Passphrase

bash

python3 scripts/password-gen.py passphrase 6
# Output: Password: lambda-window-yellow-nu-mu

Analyze Password

bash

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:

bash

# 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:

bash

# 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.

bash

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)

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

Installation

Terminal bash


openclaw install password-gen
