Advanced Options

Generate strong, secure random passwords with customizable length and character sets. Create passwords that meet specific requirements for uppercase letters, lowercase letters, numbers, and special characters. Our password generator uses cryptographically secure random number generation to ensure truly random passwords that are resistant to brute-force attacks.

What is Password Generator?

A password generator is a tool that creates random passwords using a cryptographically secure random number generator. Strong passwords are essential for protecting online accounts, as they make it significantly harder for attackers to guess or crack your credentials through brute-force methods. A good password generator allows you to customize the length and character types to meet specific security requirements.

Common Use Cases

  • Creating secure account passwords for online services
  • Generating API keys and tokens for applications
  • Creating temporary access credentials
  • Generating passwords that meet specific policy requirements
  • Creating unique passwords for multiple accounts
  • Generating passwords for development and testing environments

How It Works

The password generator uses the Web Crypto API to generate cryptographically secure random values. You can specify the password length (typically 12-128 characters) and choose which character sets to include: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special characters (!@#$%^&*). The generator ensures each selected character type appears at least once in the password, then fills the remaining length with random characters from the selected sets.

Examples

Strong password with all character types (16 characters)

Input:
Length: 16, Include: Uppercase, Lowercase, Numbers, Symbols
Output:
K9#mP2$vL8@xQ4!n

Alphanumeric password (20 characters)

Input:
Length: 20, Include: Uppercase, Lowercase, Numbers
Output:
