Secure Password Generator
Last updated: August 28, 2026
Set a length, pick character sets, generate. Uses your browser's cryptographic random source — the password never leaves your device.
How it generates
Passwords come from crypto.getRandomValues — the browser's cryptographic random source, not Math.random. You choose the length (8-64) and which sets to include: uppercase, lowercase, digits, symbols. Ambiguous characters (l, 1, I, O, 0) can be excluded for passwords you will read aloud or type from paper.
Use cases
One unique password per account — the single habit that beats most credential-stuffing attacks. API keys and wifi passwords. Anything you would otherwise have reused.

Frequently asked questions
Are the passwords really random?
Yes — crypto.getRandomValues is a CSPRNG, the same class of source used by password managers.
Can you see my password?
No. Generation happens in your browser; nothing is sent or stored.
What length should I use?
16+ for anything important. Length beats complexity — a 24-character password with letters and digits outclasses an 8-character one with symbols.
