Frequently asked questions
What makes a password secure?
Length and randomness. A 20-character random password has about 128 bits of entropy: practically impossible to guess by brute force. Avoid words, dates and keyboard patterns.
Should I reuse passwords across sites?
No. If one site leaks, your other accounts are exposed. Use a unique password per site and store them in a password manager.
Does this tool store my passwords?
No. They are generated in your browser with crypto.getRandomValues (system cryptographic randomness) and are never sent or stored on any server.
