Password Generator

How This Free Password Generator Works

This tool uses the browser's built-in crypto.getRandomValues function - part of the Web Crypto API - to generate passwords with true cryptographic randomness. Unlike Math.random(), which is predictable, Web Crypto entropy comes from your operating system's randomness pool, making it suitable for security-sensitive use. Every password is generated entirely inside your browser. Nothing is sent to a server, and nothing is stored.

Choosing the Right Options

Different situations call for different password types. Here's a quick guide:

• All character types (recommended): Use uppercase, lowercase, numbers, and symbols together for maximum entropy. Best for email, banking, and any high-value account.
• Password generator without special characters: Some sites restrict which symbols are allowed. Uncheck Symbols to generate a letters-and-numbers-only password that still meets complexity requirements.
• Longer passwords, fewer character types: A 24-character letters-only password can be stronger than an 8-character password with symbols. Length beats complexity every time.
• Short PIN or numeric code: If you need a numeric code (e.g. for a phone lock or kids' device), enable Numbers only and set the length to 6 or 8.

How Long Should Your Password Be?

Length is the single most important factor in password strength - each additional character multiplies the number of possible combinations exponentially.

• 8–11 characters: Technically meets most minimum requirements, but can be cracked within hours on modern hardware if the hash is exposed.
• 12–16 characters: A solid baseline for everyday accounts. With mixed character types, this resists brute-force for years.
• 20+ characters: Recommended for email, banking, and any account used to recover other accounts. At this length, crack time reaches into millions of years.
• 32+ characters: If you use a password manager (you should), there's no reason not to use the maximum length every site allows.

How to Create Strong Passwords

A strong password is long, random, and unique to each account. Follow these principles:

• Use at least 16 characters: Length is the biggest driver of strength. A 16-character random password is exponentially harder to crack than a 10-character one.
• Mix character types: Combine uppercase, lowercase, numbers, and symbols. Each additional character type multiplies the search space an attacker must cover.
• Never use personal information: Names, birthdays, and dictionary words are the first things attackers try. Truly random passwords generated by this tool avoid all of that.
• Use a unique password per account: If one site is breached and you reuse passwords, every account sharing that password is compromised. Generate a fresh password for each service.

Common Password Mistakes to Avoid

• Using keyboard patterns: Sequences like "qwerty", "123456", or "asdfgh" are in every cracking dictionary and fall in seconds.
• Substituting letters with look-alikes: Replacing "a" with "@" or "e" with "3" (e.g. "p@ssw0rd") is well-known and adds almost no security.
• Appending numbers or symbols at the end: Adding "1!" to the end of a word is a predictable pattern. Attackers apply these transformations automatically.
• Reusing passwords across sites: Credential stuffing attacks take leaked username/password pairs and try them on hundreds of other services automatically.
• Short passwords to meet the minimum: An 8-character password just barely satisfies a requirement but can be brute-forced in hours with modern GPUs.
