Password Generator

What is a Password Generator

A password generator uses cryptographically secure random numbers (CSPRNG) to produce unpredictable password strings. Unlike human-created passwords, machine-generated passwords have no patterns exploitable by dictionary attacks or pattern matching, making them the most effective defense against credential stuffing and brute-force attacks.

Strength Reference

Length	Character Set	Brute-force Time (reference)
≤8 chars	Single type	Seconds
12 chars	Letters + digits	Years
16 chars	All (94 chars)	Thousands of years
≥20 chars	All	Age-of-universe scale

Best practices: Length matters more than complexity; use a unique password per account; pair with a password manager (Bitwarden, 1Password); enable two-factor authentication (2FA).

This tool uses crypto.getRandomValues() (CSPRNG) — generation happens entirely in your browser and nothing is uploaded to any server.

Common Use Cases

• New account registration: Generate a unique high-strength password for each site/service to prevent credential-stuffing cascades
• API keys and service credentials: Generate random secrets for database connections and third-party integrations
• Wi-Fi / shared passwords: Generate passwords that are easy to communicate verbally (optionally exclude ambiguous characters like 0OIl)
• Temporary access credentials: Generate passwords for temporary accounts or one-time shares, discarded after use

How to Use

1. Set password length (16+ recommended) and character sets (uppercase, lowercase, digits, symbols)
2. Toggle options as needed (e.g., exclude ambiguous characters, require at least one of each type)
3. Click generate, copy the password, and store it in your password manager

FAQ

Why shouldn't I create passwords myself?

Humans tend to use meaningful words, dates, and simple substitutions (like @ for a) — patterns already cataloged by cracking tools. Studies show that human-crafted "complex" passwords have far less entropy than random passwords of the same length.

Are special characters necessary?

Not strictly. A 20-character alphanumeric password (≈119 bits of entropy) is far more secure than an 8-character password with all character types (≈52 bits). Prioritize length; special characters are a bonus.

Is the generated password secure? Is it logged anywhere?

This tool uses the browser's native crypto.getRandomValues() API for client-side generation. Passwords never travel over the network and are not logged by any server. Nothing persists after you close the page.
