Frequently Asked Questions
How long should my password be?
Security experts recommend a minimum of 16 characters for important accounts (email, banking, work). Longer passwords are always stronger — a 20-character password is exponentially harder to crack than a 12-character one, even if the shorter password looks complex.
Are the generated passwords truly random?
Yes. This tool uses window.crypto.getRandomValues(), the browser's cryptographically secure random number generator. This is the same source of randomness used by security software and is far more unpredictable than Math.random().
What makes a password strong?
A strong password has: sufficient length (16+ characters), variety of character types (uppercase, lowercase, numbers, symbols), no dictionary words or predictable patterns, and is unique to each account. This tool generates passwords that meet all four criteria.
Should I memorize generated passwords?
No — you should not try to memorize random 16+ character passwords. Use a password manager (Bitwarden, 1Password, KeePass) to store them securely. You only need to memorize one strong master password for the manager.
Can someone guess my generated password?
A 16-character password using all character types has approximately 9.2 × 10³⁰ possible combinations. At one billion guesses per second, it would take longer than the age of the universe to crack by brute force.
