What is a Password Generator?

A password generator creates random, complex passwords that are difficult to guess or crack. Using a unique, strong password for each account is one of the most effective ways to protect your online security.

Toolzi's password generator runs entirely in your browser — no passwords are ever sent to a server. You can customize the length, character types, and generate multiple passwords at once.

How to Use

  1. Set the desired password length using the slider (8–64 characters).
  2. Toggle the character types you want: uppercase, lowercase, numbers, and symbols.
  3. Choose how many passwords to generate (1–10).
  4. Click Generate, then copy any password with the Copy button.

Frequently Asked Questions

How long should a password be?
At least 12 characters. For maximum security, 16 or more characters with a mix of uppercase, lowercase, numbers, and symbols is recommended.
Are generated passwords saved on your servers?
No. All passwords are generated locally in your browser and are never sent to any server.
Should I include symbols in my password?
Yes. Adding symbols greatly increases password complexity and makes brute-force attacks much harder.
How is password strength calculated?
Strength is based on the number of character types used and the total length. Weak, Fair, Strong, and Very Strong are the four levels.
Can I generate multiple passwords at once?
Yes. You can generate up to 10 passwords at once using the Count option.
Is the password generation truly random?
Yes. Passwords are generated using the browser's built-in crypto.getRandomValues() API, which is a cryptographically secure random number generator — suitable even for API keys and encryption secrets.
