How Password Generator Works
A Password Generator is a security utility used to create strong, high-entropy credentials. This tool is essential for everyone protecting accounts from brute-force attacks, securing API keys, and maintaining digital hygiene.
The generation engine handles the entropy through a cryptographic pipeline:
- Configuration: User selects length (e.g., 20) and character sets (A-Z, 0-9, !@#).
- Entropy Collection: Uses the browser's Web Crypto API (
crypto.getRandomValues()) to get truly random noise. - Assembly: Maps the noise to the selected characters.
- Validation: Ensures at least one character from each selected set is included (so "Numbers: Yes" actually includes a number).
The History of Cracking
The arms race.
- Dictionary Attacks: Hackers trying every word in the book.
- The Defense: Random characters. "Horse" is easy. "H0r$e" is harder. "9x#Lm2" is hardest.
- GPU Cracking: Modern GPUs can guess billions of passwords a second. Length is now the only defense, as detailed in NIST SP 800-63B Digital Identity Guidelines.

Security and Privacy Considerations
Your generation is performed in a secure, local environment:
- Local Logical Execution: All generation logic is performed locally in your browser. Your secrets never touch our servers.
- Zero Log Policy: We do not store or track your inputs. Your Generated Secrets remain entirely confidential.
- W3C Security Compliance: The tool operates within the standard browser sandbox, following the OWASP Password Storage Cheat Sheet recommendations for entropy and randomness.
- Privacy First: To maintain absolute Data Privacy, the tool functions as an anonymous utility.
