# Configure Source Authentication

Flow Plus enables you to configure source authentication to validate the integrity and origin of incoming webhooks. Enabling this step adds an extra layer of security to ensure webhooks are coming from a trusted source. 

To configure:

1. Within the Configure Source Authentication module, select **Configure**
2. From the dropdown, select the Authentication Method
3. Flow Plus enables users to select from 1 of 3 options or to skip authentication altogether:
   1. Basic Authentication
   2. Shared Secret Authentication
   3. Hash-based Message Authentication Code (HMAC) 
4. Simply follow the prompt for the Authentication method selected and click **Save**
