What makes a strong password?

A strong password combines length and character variety. Longer passwords are exponentially harder to brute-force — 16+ characters is a solid baseline. Mixing uppercase, lowercase, digits, and symbols expands the character space, making exhaustive attacks impractical.

Tips for using generated passwords

Use a password manager (Bitwarden, 1Password, etc.) to store generated passwords — you don't need to memorise them.
Use a unique password for every account. Reusing passwords means a single breach exposes everything.
Enable two-factor authentication (2FA) wherever possible — it adds a layer no password alone can provide.
Never type or paste passwords into sites over HTTP (no padlock in the browser).

How the generator works

Passwords are built using the browser's built-in crypto.getRandomValues() API, which provides cryptographically secure random numbers. No Math.random() — no predictable patterns. Nothing is sent over the network; the entire process happens locally on your device.
