About this tool

This tool generates cryptographically secure random passwords and strings. You can choose the length of the password and select the characters you want to include in the generated password: lowercase letters, uppercase letters, numbers, and symbols.

This tool uses the browser's built-in crypto.getRandomValues function to generate random numbers. This function is available in most modern browsers. It will fall back to Math.random if the function is not available.

Why use a password generator?

Passwords generated by this tool are more secure than passwords that are easy to remember. They are also more secure than passwords that are easy to guess or that are based on personal information.

Using a password generator can help you create strong passwords that are difficult to crack. This can help protect your online accounts from being hacked or compromised.

Best practices for using passwords

Here are some best practices for using passwords generated by this tool:

  • Use a unique password for each account: Do not reuse passwords across multiple accounts. If one account is compromised, all accounts with the same password are at risk.
  • Generate strong passwords: Use a password generator to create strong, random passwords that are difficult to guess. Strong passwords typically include a mix of lowercase letters, uppercase letters, numbers, and symbols.
  • Generate long passwords: Longer passwords are generally more secure than shorter passwords. Consider generating passwords that are at least 15 characters long.
  • Use a password manager: Consider using a password manager to store and manage your passwords securely. A password manager can help you generate strong passwords, store them securely, and autofill them when needed.
  • Enable two-factor authentication: Enable two-factor authentication (2FA) on your accounts whenever possible. 2FA adds an extra layer of security by requiring users to provide two forms of identification to access their accounts.

Is it safe to use a password generator and this tool?

This tool generates passwords and strings directly in your browser using JavaScript. The generated passwords are not sent over the internet or stored on a server. The passwords are generated locally on your device and are not shared with anyone.
