# Automatic Linking

UAE Pass UUID or Emirates ID should be used to link the user. The service provider should maintain a reference to either values to allow the user to login.

Other attributes should always be compared & updated at every login in the service provider system as they can be changed by the user at anytime.

{% hint style="danger" %}
Note: Linking should be done based on **UUID** and **Emirates ID** only, since UAEPASS provides an option to change the Email and Mobile in UAEPASS account. 
{% endhint %}
