What Makes a Strong Password?

A strong password combines several qualities that make it resistant to guessing, brute-force attacks, and dictionary attacks:

• Length — Every extra character multiplies the search space exponentially. Aim for at least 16 characters; 20+ for high-value accounts.
• Character diversity — Mixing uppercase letters, lowercase letters, numbers, and symbols dramatically increases complexity. A 16-character password using all four sets has over 6 septillion possible combinations.
• No dictionary words — Even cleverly spelled words (p@ssw0rd) are trivially cracked by modern tools. Truly random character strings are far harder to attack.
• No personal info — Avoid birthdates, names, phone numbers, or anything that could be guessed from your public profile.

Why Use This Generator?

• Cryptographically secure — Uses crypto.getRandomValues(), the same API browsers use for TLS — not the weak Math.random()
• Runs locally in your browser — Your password never leaves your device; nothing is sent to any server
• No data stored — History is session-only and cleared when you close or refresh the page
• 100% free — No account, no sign-up, no limits
• Fully customizable — Pick your length, character sets, and exclude confusing characters like 0/O or l/1

Password Security Tips

• Never reuse passwords. If one site is breached, attackers try the same credentials everywhere (credential stuffing).
• Use a password manager. Tools like Bitwarden, 1Password, or your browser's built-in manager can store unique passwords for every site without you needing to remember them.
• Enable two-factor authentication (2FA). A strong password plus a TOTP code or hardware key makes an account almost impossible to compromise remotely.
• Change passwords after breaches. Check services like Have I Been Pwned to find out if your credentials have been exposed in a data breach.
