Password Generator
Strong, random passwords — cryptographically secure, no upload.
Why use a random password generator?
Human-chosen passwords tend to follow predictable patterns — dictionary words, birthdays, keyboard walks. Attackers exploit this with brute-force and dictionary attacks. A random password generator eliminates these patterns entirely, creating passwords that are practically impossible to guess. This tool uses the browser's crypto.getRandomValues API, which is cryptographically secure and never sends your password to any server.
How password strength is scored
Strength is determined by two factors: length and character set diversity. A longer password has exponentially more combinations — every extra character multiplies the search space. Using all four character sets (uppercase, lowercase, numbers, symbols) further multiplies entropy. The strength indicator updates live as you adjust the sliders and checkboxes.
Frequently asked questions
How long should a password be?
Security experts recommend at least 16 characters for general accounts and 24+ for high-value accounts like banking or email. This tool defaults to 16 characters, which offers excellent protection against modern brute-force attacks.
Is my password sent to any server?
No. Everything happens in your browser. The password is generated using the Web Crypto API and never leaves your device. This page has no analytics that capture form inputs.
Should I use a password manager?
Yes. Generate a unique password for every account here, then store them in a password manager like Bitwarden, 1Password, or your browser's built-in vault. Never reuse passwords — a breach on one site would expose all accounts that share the same password.
