Secure Password Generator

Why Random Generation Beats Anything You'd Think Up

Humans are bad at picking randomness — patterns, keyboard walks, and personal references always leak in. This generator uses crypto.getRandomValues(), the same cryptographically secure random number source browsers use for encryption keys, so every character is drawn independently with no bias attackers can model.

A 16-character password using all four character types has roughly 100 bits of entropy — effectively uncrackable by brute force with current or foreseeable computing power. Length matters more than complexity: a 20-character lowercase-only password can still beat a 10-character mixed one.

Generate, Then Store — Don't Memorize

A random 16+ character password isn't meant to be memorized — it's meant to be saved in a password manager and reused nowhere else. Generate a unique one for every account. If you need to check how strong an existing password is instead, try our Password Strength Checker or check whether it's already been exposed in a breach with our Leaked Password Checker.
