How to Use the Vauz Autofill Browser Extension
Overview
After successfully registering your Vauz browser extension, you can start using it to automatically fill login credentials and other form data on websites. The extension provides two autofill modes to suit different preferences and security needs
Before using the extension: Make sure you've completed the extension registration process first
Autofill Modes
Logo Mode (Recommended)
Logo Mode is the default and most secure way to use the Vauz extension. It shows a Vauz logo icon in compatible form fields.
Step 1: Navigate to a Login Page
Go to any website that requires login credentials stored in your Vauz vault
Step 2: Look for the Vauz Logo
The Vauz logo will appear in username and password input fields on the page

Step 3: Choose Your Action
In the Vauz Autofill settings you can choose to either:
- Autofill first match: Automatically fills the first matching credential from your vault
- Show credentials list: Displays a dropdown with all matching credentials for that website

Step 4: Select and Fill
If you chose to show the credentials list, select the appropriate credential from the dropdown. The extension will fill both username and password fields automatically, if found

Auto Mode (Advanced)
Auto Mode automatically fills first matching credential when you focus on form fields. This is more convenient but less secure
Security Warning: Auto Mode may expose your credentials on compromised websites. Use this mode at your own risk
Step 1: Enable Auto Mode
- Click the Vauz extension icon in your browser toolbar
- Switch to
Autofill on field focusin Autofill Mode section

Step 2: Navigate to Login Fields
Go to a website with login forms. The extension will automatically detect and fill compatible fields when you click on them

Step 3: Review Filled Data
Always verify that the correct credentials have been filled before submitting the form
