Secure Password Generator

Generate strong, random passwords to protect your online accounts. Our tool uses the cryptographically secure window.crypto API built into your browser, ensuring that the random numbers generated are unpredictable and safe for security-critical use.

What makes a password strong?

  • Length: The length of a password is the most critical factor. We recommend at least 16 characters for critical accounts.
  • Complexity: Mixing uppercase, lowercase, numbers, and symbols increases entropy, making brute-force attacks exponentially harder.
  • Unpredictability: Humans are bad at being random. Machines using CSPRNGs (Cryptographically Secure Pseudo-Random Number Generators) create truly random strings.

Security Best Practices

  • Use Unique Passwords: Never reuse the same password across multiple sites. If one site is breached, your other accounts remain safe.
  • Use a Password Manager: Don't try to memorize complex random passwords. Use a secure vault like TechnicalHeist to store them.
  • Enable 2FA: Whenever possible, enable Two-Factor Authentication for an extra layer of security.
