FAQ
Q. Are these passwords stored on your server?
Absolutely not. All generation happens locally in your browser and is never transmitted.
Q. What makes a password 'strong'?
A mix of different character types and a length of at least 12-16 characters is recommended.
Use Cases
- Account Security: Creating unique, complex passwords for new online registrations.
- System Administration: Generating temporary initial passwords for new users or employees.
- API Keys: Creating random strings for authentication tokens or secret keys.
Technical Deep Dive
This tool uses a Cryptographically Secure Pseudo-Random Number Generator (CSPRNG). Unlike standard random functions, CSPRNG ensures high entropy and unpredictability, making the passwords resistant to statistical analysis.
Limitations
- The security of your password also depends on how you store it; always use a reputable password manager.
