Frequently Asked Questions
What makes a password strong?
Length and randomness. A long password (12–16+ characters) mixing uppercase, lowercase, numbers, and symbols has so many combinations that brute-forcing it is impractical. Avoid dictionary words and personal info.
Is it safe to generate a password here?
Yes. The password is generated locally in your browser using the crypto random API and is never sent anywhere. For extra safety, generate it on your own device and store it in a password manager.
Should I reuse strong passwords?
No. Even a strong password becomes a risk if reused, because one breached site exposes every account sharing it. Use a unique password per site, managed by a password manager.
