Frequently Asked Questions
How secure is this password generator?
This generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same standard used by modern operating systems and is considered secure for generating passwords.
What makes a password strong?
A strong password is long (16+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, and is completely random — not based on dictionary words or personal information.
How long should my password be?
For most accounts, 16 characters is the minimum recommended length. For highly sensitive accounts (banking, email), use 20+ characters. With mixed character types, a 16-character password has approximately 95 bits of entropy.
Are passwords stored or logged?
No. All password generation happens entirely in your browser using JavaScript. No data is sent to any server. Your generated passwords are completely private.
Should I use a password manager?
Yes. Use a password manager like Bitwarden, 1Password, or Dashlane to store unique, complex passwords for every account. Never reuse passwords.
