Frequently Asked Questions
Are the generated passwords saved anywhere?
No. Passwords are generated entirely in your browser using the Web Crypto API. They are never sent to any server or stored anywhere. Once you close the tab the password is gone.
What makes a password strong?
Three factors determine strength: length (more characters means exponentially more guesses to crack), variety (mixing uppercase, lowercase, numbers, and symbols), and unpredictability (no dictionary words, names, or dates). The strength bar in this tool scores all three as you adjust the options.
How should I store the generated password?
Use a reputable password manager like Bitwarden, 1Password, or Dashlane. They store passwords encrypted and autofill them for you, so you only need to remember one strong master password.
How long should my password be?
16 characters is a practical minimum for most accounts. Use 20 or more for high-value accounts such as email or banking. Anything under 12 characters is considered weak by current security standards — modern hardware can crack short passwords in seconds.
What are best practices for using generated passwords?
Save the password to your manager immediately after generating it — do not reuse it across multiple sites. Enable two-factor authentication (2FA) wherever available as a second layer of defense. Review and rotate passwords for critical accounts at least once a year.
Does length or character variety matter more?
Length has a bigger impact. A 20-character password using only lowercase letters has more entropy than a 12-character password with symbols. That said, combining both — long and varied — gives you the strongest result, which is why this generator defaults to all character types.
