Strong Password Generator FAQ

What makes a password truly strong?

Three key properties: length (14+ characters), character diversity (all types), and true randomness (cryptographic, not human-chosen). Our generator ensures all three.

How many characters should a strong password have?

14 minimum for most accounts, 16-20+ for critical accounts like email and banking. Our tool supports up to 128.

Is this generator free?

Yes, completely free. No limits, no signup, no data collection. Everything runs in your browser.

How does this compare to LastPass, 1Password, or Dashlane generators?

Same cryptographic security, but completely free and requires no account. We never store or transmit your passwords. Consider using our tool alongside a password manager.
