Why Use a Password Generator?

In today's digital landscape, a strong password is your first line of defense against cyber attacks, data breaches, and identity theft. Humans are notoriously bad at creating random passwords, often relying on predictable patterns, birth dates, or dictionary words.

What Makes a Password Strong?

  • Length: The longer the password, the harder it is to crack. 12 characters is the modern minimum, but 16+ is recommended for critical accounts.
  • Complexity: It should include a mix of uppercase letters, lowercase letters, numbers, and symbols to exponentially increase the possible combinations.
  • Unpredictability: It must not contain dictionary words, predictable sequences (like "1234" or "qwerty"), or personal information.
  • Uniqueness: Never reuse passwords across different sites. If one site is breached, your other accounts remain secure.

Is this tool secure?

Yes. This password generator runs entirely in your web browser using client-side JavaScript. No passwords are ever sent to our servers or stored anywhere on our network. As soon as you generate a password, it exists only on your device.

Time to Crack

An 8-character password with only lowercase letters can be cracked by a modern computer in seconds. Increase that to 12 characters with a mix of uppercase, lowercase, numbers, and symbols, and it would take thousands of years to brute-force crack using current technology.

Best Practices

  • Use a Password ManagerTools like Bitwarden, 1Password, or Apple Keychain store your complex passwords securely so you don't have to memorize them.
  • Enable 2FA (MFA)Always enable Two-Factor Authentication on your important accounts as a second layer of security.
  • Check HaveIBeenPwnedPeriodically check if your email address has been involved in any known data breaches.

How the calculation works

Each character is drawn from the selected set. With uppercase, lowercase, digits, and the generator's symbol list all turned on, the set has a fixed size.

Alphabet = 26 + 26 + 10 + 29 symbols = 91 Combinations = 91^length

The default length is 16 characters. The bit count is log base 2 of the number of possible passwords.

Worked example: 16 characters from the full default set

  1. The symbol list has 29 characters, so the alphabet has 91.
  2. A 16-character password from that alphabet has 104.1 bits of combinations.
  3. A 12-character password from the same set has 78.1 bits.
