Install Step 4: Installing Fast Login Buttons on BigCommerce
There are 2 different pages where you can install our Fast Login button:
- Login Page
- Create Account Page
Let's get started:
Installing Fast Login Button to Login Page
- In the theme files, click templates > pages > auth > login.html.
- Use command-F to find the line:
