# 4.12.7 NFC Based Authentication

*"NFC allows the system to not only identify the user but also provide a very high level of security that the tag/card (and therefore the username that the tag/card is attached to) is in fact the user it claims to be."*

To configure the NFC Based Authentication, follow the below steps -

1. Go to the **Authentication** tab in the sidebar.\\
