Why Use a Password Generator?

Human-chosen passwords are predictable. People reuse names, birthdays, and common words — all of which attackers exploit first. A random password generator removes that bias entirely.

Every password generated here is created in your browser using JavaScript's built-in randomness. Nothing is sent to a server, stored in a database, or logged anywhere. The moment you close the tab, the password is gone — only you have it.

How to Use This Password Generator

Four steps to a strong password:

1

Set the length — drag the slider anywhere from 8 to 64 characters

2

Choose your character types — uppercase, lowercase, numbers, symbols

3

The password generates automatically — or click Generate for a new one

4

Click Copy and paste it directly into your password manager or account

What Makes a Password Strong?

Password strength comes from two things: length and variety. Both matter.

Length

Every extra character multiplies the number of possible combinations. A 16-character password has billions of times more combinations than an 8-character one.

Variety

Using uppercase, lowercase, numbers, and symbols expands the character pool from 26 to 72. This makes brute-force attacks vastly slower.

Randomness

Predictable patterns — names, dates, keyboard walks — are tried first by attackers. True randomness removes all patterns.

Uniqueness

Reusing passwords across sites means one breach exposes all your accounts. Each account needs its own password.

The strength indicator uses entropy — the number of bits needed to represent all possible passwords of that length and character set. Very Strong means 80+ bits, which is beyond practical brute-force attack with current hardware.

Password Best Practices

  • Use a different password for every account — never reuse
  • Use a password manager (Bitwarden, 1Password, or your browser) to store them
  • Enable two-factor authentication (2FA) wherever possible
  • Never share a password over email, SMS, or chat
  • Change passwords immediately if a site you use reports a breach
  • Aim for 16+ characters — longer is always better

Frequently Asked Questions

Yes — all passwords are generated directly in your browser. Nothing is sent to any server, stored, or logged. Your generated passwords are completely private.

A strong password should be at least 16 characters long and include uppercase letters, lowercase letters, numbers, and symbols. Longer is always better.

Yes — completely free, no sign-up required, works on any device.

A strong password combines length (16+ characters) with variety — uppercase, lowercase, numbers, and symbols. Avoid dictionary words and personal information.

Strength is calculated from the number of possible combinations (entropy). Weak is under 40 bits, Fair is 40–59, Strong is 60–79, and Very Strong is 80+ bits. A 16-character password with all character types reaches Very Strong.
