What is Password Generator?

Password Generator is an online tool that creates strong, random passwords for accounts, API keys, and test environments. Weak passwords remain the leading cause of security breaches — a dedicated generator ensures every password uses sufficient length and character diversity.

Unlike memorable passwords that humans tend to create (names, dates, common words), cryptographically random passwords resist dictionary attacks, brute force, and credential stuffing. Developers need strong passwords for staging environments, service accounts, database users, and personal account registration.

WaiHub's Password Generator uses crypto.getRandomValues for cryptographically secure randomness. Customize length (4-128 characters), toggle uppercase, lowercase, numbers, and symbols, exclude ambiguous characters, and see a live strength meter. Passwords are generated in your browser and never uploaded.
