Password Generator

How to Use the Password Generator

Use the length slider to choose a password length between 8 and 128 characters. The default of 16 characters provides a strong balance between security and usability. Toggle which character types to include — uppercase letters, lowercase letters, numbers, and symbols — then click Regenerate Password to create a new password that matches your criteria.

The generated password appears instantly in the display box at the top. Click the Copy button to copy it to your clipboard and paste it directly into your password manager or the site you are signing up for. The strength meter updates in real time as you adjust settings, helping you make an informed decision about how secure your password is.

For maximum security, aim for at least 16 characters with all four character types enabled. This gives you a password with an enormous search space that would take centuries to crack with modern hardware. Passwords under 12 characters or using only one character type are rated Weak or Fair and should be avoided for important accounts.

What Makes a Password Strong?

Password strength is determined by two main factors: length and character variety. A longer password takes exponentially more time to guess through brute force. A 16-character password using all character types has over 90 septillion possible combinations — far beyond what even the fastest computers can test in a reasonable time.

Character variety also matters because it increases the size of the search space. Using only lowercase letters gives 26 possibilities per character. Adding uppercase doubles it to 52. Adding digits brings it to 62, and adding symbols can push it past 90 characters per position. Each additional character type multiplies the difficulty exponentially.

Avoid common password patterns like dictionary words, keyboard walks (qwerty, 12345), or personal information. Even "complex" passwords like P@ssw0rd are in attacker wordlists and crack instantly. A truly random password — which this generator produces using the browser's crypto.getRandomValues() API — is the most secure option.

Store your generated passwords in a reputable password manager such as Bitwarden, 1Password, or KeePass. Never reuse passwords across sites, and enable two-factor authentication wherever possible.

Privacy

All passwords are generated entirely in your browser using the Web Cryptography API (crypto.getRandomValues()). No passwords, settings, or any data are sent to our servers or stored anywhere. Your generated passwords are never visible to anyone but you.
