What is the Password Converter?

The Password Converter is a deterministic password generator. It creates a strong, unique password by combining two inputs: a secret "master password" that the user remembers, and a "salt" (a unique keyword for each website, like "google.com"). The same master password and salt will always produce the exact same unique password, but changing either input will result in a completely different output.

History of this Feature

This tool is an alternative to traditional password managers. Instead of storing a vault of passwords that could be compromised, this approach relies on a mathematical algorithm (PBKDF2) to generate passwords on the fly. The concept of deterministic password generation has been around in security circles for years. Our tool implements this concept in a user-friendly, browser-based interface, providing a secure way to manage passwords without storing them anywhere.

Who Commonly Uses This Feature?

This tool is used by security-conscious individuals who prefer not to use a traditional password manager. It's for people who are comfortable remembering one strong master password and a system for their "salts" (e.g., always using the website's domain name). It offers a high level of security as the generated passwords are never stored or transmitted.

How to Use the Password Converter

This tool allows you to create strong, unique passwords for every website using just one "master password" that you remember.

  1. Enter Your Master Password: Type in a secret password that you can easily remember. This is the key to all your other passwords.
  2. Enter a Salt: In the "Salt" field, enter a unique keyword for the specific website or service (e.g., "google.com", "facebook", "my-bank").
  3. Customize: Adjust the "Password Length" and select which character types (Uppercase, Lowercase, Numbers, Symbols) you want to include in the output.
  4. Get Your Password: A strong, unique password will be generated automatically.

The key feature is that the same master password and salt will always create the exact same generated password. This means you don't have to store your passwords anywhere. Just remember your master password and the salt you used for each site.

Security Note: This process is deterministic and not reversible. Your master password is never stored or sent anywhere.
