Frequently asked questions
How long should a password be?
Length beats complexity: 16 random characters is effectively unbreakable even with symbols excluded. Use 20+ for master passwords.
Is the generator secure?
It uses the browser's cryptographically secure random source (crypto.getRandomValues) and never sends anything to a server.
Should I memorize these?
No — store passwords in a password manager and use unique ones per site. A manager is the practical way to keep 100+ strong passwords.
