## What is sgID?

sgID is a Singapore government identity provider that allows Singapore residents to **authenticate with applications** and **share government-verified data** about themselves via the Singpass mobile app. 

Some examples of products that have integrated with sgID are Singapore's [National Health Appointment System](https://book.health.gov.sg/) and [FormSG](https://form.gov.sg/).
