+# Passkey Authentication Setup
+
+Passkeys provide a **passwordless authentication** experience using WebAuthn. This guide explains how to enable, configure, and use **Passkey authentication** in **LibreChat**.
+
+## 1. Configuration
+
+Passkey authentication requires the following environment variables to be configured in your `.env` file.
+
+### Basic Configuration
+
+To enable **Passkey authentication**, set these environment variables:
+
+<OptionTable
+    options={[
+        ['PASSKEY_ENABLED', 'boolean', 'Enable or disable Passkey authentication.', 'PASSKEY_ENABLED=true'],
+        ['RP_ID', 'string', 'The relying party ID (RP ID) which should match your domain name (without http:// or https://).', 'RP_ID=localhost'],
+    ]}
+/>
+
+Additionally, ensure **social login and registration** are enabled:
+
+<OptionTable
+    options={[
+        ['ALLOW_SOCIAL_LOGIN', 'boolean', 'Enable social login options.', 'ALLOW_SOCIAL_LOGIN=true'],
+        ['ALLOW_SOCIAL_REGISTRATION', 'boolean', 'Enable social registration options.', 'ALLOW_SOCIAL_REGISTRATION=true'],
+    ]}
+/>
+
+> **Note:** The `RP_ID` must match your domain (e.g., `example.com`) and should not include `http://` or `https://`.
+
+---
+
+## 2. Passkey Authentication Workflow
+
+### Login Process
+1. **User enters their email** in the login screen.
+2. **Browser prompts Passkey authentication** (Face ID, Touch ID, security key, or device authentication).
+3. **User verifies using biometrics or a security key**.
+4. **The passkey response is sent to the backend for verification**.
+5. **If successful, the user is logged in** without needing a password.
+
+### Registration Process
+1. **User enters their email** in the registration screen.
+2. **A passkey challenge is generated and sent to the browser**.
+3. **User verifies using biometrics or a security key**.
+4. **The passkey is stored on the user’s device**.
+5. **If successful, the user is registered without a password**.
+
+---
+
+## 3. User Interface Updates
+
+### Login Page Enhancements
+- Users can log in using a Passkey instead of a password.
+- If a passkey is available, the browser will prompt biometric authentication.
+
+### Registration Page Enhancements
+- Users can register using Passkeys.
+- If supported, their browser will prompt them to save a passkey.
+
+### Account Settings
+- Users can view and manage their saved passkeys.
+- Passkeys can be removed from their profile if necessary.
+
+---
+
+## 4. Security Considerations
+
+- **Passkeys should only be used over HTTPS** (except for `localhost` in development).
+- **RP ID must match the deployment domain** to prevent phishing.
+- **Multi-device Passkeys are supported** (Google Password Manager, iCloud Keychain, etc.).
+- **Users should have an option to delete Passkeys** from their account settings.

+
+## 6. Testing Your Setup
+
+To ensure Passkey authentication works correctly:
+
+1. **Enable Passkeys in `.env`** (`PASSKEY_ENABLED=true`).
+2. **Restart the server** for changes to take effect.
+3. **Open the login or registration page**.
+4. **Attempt Passkey authentication** using Face ID, Touch ID, or a security key.
+5. **Verify login and registration success.**
