What Makes a Password Strong? A Complete Security Guide

A strong password is long, random, and uses a mix of letters, numbers, and special characters. Most data breaches happen because people use weak, reused, or easily guessable passwords. This free password generator uses your browser's built-in cryptographic system (the Web Crypto API) to create truly random, secure passwords that are never sent to any server.

What Makes a Password Weak?

Too short

"pass" or "1234"

Can be cracked in milliseconds.

Personal info

"john1990"

Easy to guess from social media.

Common words

"password", "qwerty"

First on every hacker's list.

Reused passwords

Same on 10 sites

One breach exposes all accounts.

Password Strength by Length

Password length is the single most important factor in password security. Here is how crack time roughly scales with password length (using a mix of all character types):

6 characters
Less than 1 second
8 characters
~5 hours
10 characters
~3 years
12 characters
~34,000 years
16 characters
Billions of years

How This Password Generator Works

This tool uses the Web Crypto API built into every modern browser. This is the same cryptographic system used by banking websites and security software. The password is generated entirely on your device. It is never sent to our servers, never logged, and never stored anywhere. You can verify this by turning off your internet and the tool will still work perfectly.

How to Store Your Passwords Safely

Generating a strong password is step 1. Storing it safely is step 2. Never write passwords on sticky notes or store them in plain text files on your computer. The best way to manage passwords is to use a trusted password manager.

  • Bitwarden (free and open-source)
  • Dashlane
  • 1Password
  • NordPass
  • Apple Keychain (for Apple users)
  • Google Password Manager (for Chrome users)

Essential Password Security Rules

  1. 1Use a different password for every single account. Never reuse passwords.
  2. 2Enable Two-Factor Authentication (2FA) on every important account.
  3. 3Use at least 12 characters. 16 or more is even better.
  4. 4Include uppercase, lowercase, numbers, AND symbols.
  5. 5Never share your passwords, even with people you trust completely.

Password Generator, Frequently Asked Questions

Is this password generator safe to use?

Yes, completely. This tool uses the Web Crypto API to generate passwords directly in your browser. Your passwords are never transmitted to any server. They exist only on your device.

How long should my password be?

For most accounts, 12 to 16 characters is a very good length. For critical accounts like your email, banking, or password manager, use 20 characters or more.

Should I use symbols in my password?

Yes. Adding symbols like @, #, $, and ! significantly increases the number of possible combinations, making brute-force attacks much harder and slower.

What is the safest way to store my passwords?

Use a reputable password manager like Bitwarden (free) or 1Password. Never save passwords in a plain text file or write them on paper near your computer.

What is Two-Factor Authentication (2FA) and should I use it?

Two-Factor Authentication adds a second verification step (like a code to your phone) when you log in. Even if someone steals your password, they cannot get in without your second factor. You should always enable it.

Can I use a passphrase instead of a random password?

Yes. A passphrase is a sequence of random words like "correct-horse-battery-staple". They are easy to remember and very secure when they are long enough (4 or more random words).
