FAQ
What makes a strong password?

A strong password has at least 12 characters and combines uppercase letters, lowercase letters, numbers and special symbols. Avoid dictionary words, names, or repeated patterns. Use a unique password for every account.

Is the generated string secure?

Generation happens entirely in your browser β€” nothing is sent to any server. The randomness comes from Math.random(), which is suitable for most non-cryptographic purposes. For cryptographic keys, use a dedicated tool with a CSPRNG.
