Password Generator

Generate strong random passwords using the HeffTools API. Choose length and character set, then copy the result into your apps, accounts, or automation scripts.

Recommended: 12–64 characters for most accounts.
Use Strong for maximum security. Simpler sets can be useful for systems with character restrictions.

Generated Password

This password is generated by the same API you can call from scripts and services.

Backed by GET /api/v1/password/generate?length=&charset=

How to Use the Password Generator

  1. Choose your desired password length (at least 12 for most real-world usage).
  2. Select a character set:
    • Strong – letters, digits, and symbols for maximum entropy.
    • Alphanumeric – letters and digits only, good for systems that disallow symbols.
    • Letters only – for simple test passwords or special constraints.
    • Digits only – for numerical codes or systems that require numeric passwords.
  3. Click Generate to request a password from the HeffTools API.
  4. Click Copy to place the generated password on your clipboard.

Password Best Practices

  • Use a unique password for every important account.
  • Prefer 12–16+ characters whenever possible.
  • Include uppercase, lowercase, digits, and symbols for stronger security.
  • Store passwords in a trusted password manager, not in plain text files.
  • Avoid obvious patterns like Password123! or personal information.

Calling the Password API from Your Code

This page uses the same HTTP endpoint that you can integrate in your own tools: 

GET /api/v1/password/generate?length=16&charset=strong

Example response:

{
  "charset": "strong",
  "length": 16,
  "password": "tmL_ph6w5Cug:ZAV"
}
