Generate strong, secure passwords with custom rules
A password generator creates strong, random passwords that are practically impossible to guess or brute-force. Human-chosen passwords follow predictable patterns — names, dates, keyboard walks like "qwerty123" — and attackers exploit those patterns with dictionary attacks that test billions of combinations per second. This tool uses your browser's cryptographically secure random number generator (the Web Crypto API) to produce passwords with no pattern at all, mixing uppercase, lowercase, digits and symbols at the length you choose.
Password strength grows exponentially with length and character variety: a random 16-character password with all character classes would take longer than the age of the universe to brute-force with current hardware. Generation happens entirely on your device — the password is never transmitted, stored or logged anywhere, so the only copy that exists is the one on your screen.
At least 12 characters; 16 or more is recommended for anything important. Each extra character multiplies the cracking time enormously — a 16-character random password with mixed character types is effectively uncrackable with today's hardware.
Yes. The tool uses the Web Crypto API (crypto.getRandomValues), the same cryptographically secure source browsers use for TLS. It is not based on predictable functions like Math.random().
No. Generation runs entirely in your browser — nothing is sent to a server, saved or logged. Once you close or refresh the page, the password is gone unless you copied it.
Absolutely. Password reuse is the #1 cause of account takeovers: when one site is breached, attackers try the leaked credentials everywhere else. Generate a unique password per site and keep them in a password manager.
