Quick answers for Password Generator
How strong are the passwords from the Password Generator?
The Password Generator uses the browser's crypto.getRandomValues - cryptographically secure randomness - so a 16-character password with full character variety is well beyond brute-force range for any modern attacker.
Does the Password Generator store or log my passwords?
No. Passwords are generated in your browser and never sent anywhere. Nothing is logged, stored, or cached - close the tab and the password is gone unless you saved it to your password manager.
What length should I choose?
Use at least 16 characters for everyday accounts, and 20+ for high-value logins (banking, email, password-manager master passwords). Length beats complexity - every extra character roughly doubles the brute-force cost.
Should I include special characters?
Yes, unless a site blocks them. Special characters expand the search space and defeat dictionary attacks. The Password Generator lets you exclude ambiguous characters (like l/1 and O/0) for when you need to type the password by hand.
What does the strength indicator mean?
It estimates entropy from the chosen length and the size of the active character pool. "Weak" is below ~36 bits, "Fair" up to ~60, "Strong" up to ~100, and "Very strong" beyond that. For online accounts, aim for Strong or higher.
