Generate, don't store!

The Stateless Password Generator. Your brain is the database

pwdr is a hybrid password generator designed for those who want to move away from cloud-synced vaults and physical notebooks. Instead of storing passwords, you calculate them using a Master Secret and a logical Key system

🌍 Anywhere You Are

pwdr is designed to be available wherever you need a password

• 🌐 Web: Use it as a standalone Web App
• 🧩 Chrome Extension: Generate and copy passwords directly from your browser toolbar
• 🤖 Telegram Mini App: Access your "vault" on the go through Telegram

💡 The Philosophy: Mental Composition

The core idea is to eliminate the need to "save" anything. By using a mental system for your keys, you carry your entire password vault in your head without actually memorizing hundreds of strings

1. The Secret Phrase: One strong, complex phrase you never forget
2. The Key System: A logical rule you create for yourself to generate keys on the fly
   • Example: [Service Name] + [Year of Account] + [A Personal Keyword]
   • Resulting Keys: github2024coffee, gmail2018coffee, netflix2021coffee
3. The Output: pwdr processes these to generate high-entropy, unique passwords for every service

✨ Main Features

• 🧠 100% Deterministic: Same inputs, same output. Every single time
• 🛡️ Identity Signature: Every Secret Phrase produces a unique visual/textual signature. This allows you to instantly verify you haven't made a typo in your master phrase before generating passwords
• ⚙️ Tunable Local Security: Choose how heavily to encrypt your Secret Phrase locally. Higher strength increases protection against brute-force attacks on your device's storage at the cost of a slightly longer generation time
• 🔒 Encrypted Local Vault: For convenience, your Secret Phrase can be AES-encrypted and stored in your browser's local storage
• ⚡ PIN Quick-Unlock: Use a simple PIN to unlock your vault so you don't have to type your long Secret Phrase for every new password
• 🚫 Offline & Private: No servers, no tracking, and no data collection. It works entirely in your browser

🛠 How It Works

1. Initialize: Set a master PIN to lock the app interface
2. Enter Secret: Input your "Master Secret Phrase"
3. Verify Signature: Check the Signature on screen. If it matches your "usual" signature, you know your input is 100% correct.
4. Compose Key: Use your personal mental logic to enter a Key for the service you need.
5. Copy & Go: Use the generated password. No saving required.

📦 Under the Hood

As a tool built by a developer for users who value architectural transparency, the engine is fully open-source

• Engine:
  • pwdr npm package
  • pwdr GitHub repository
• Security: Uses cryptographic hashing to ensure that even a tiny change in the Key results in a completely different password

⚠️ Important Considerations

• Statelessness: No data is synced. If you change your Master Secret, all passwords change
• Persistence: Data is kept in local storage. If you clear your browser data, you will need to re-input your Master Secret Phrase
• Total Responsibility: There is no "Recovery" or "Forgot Password" link. Your memory is the only backup
