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.
