# Notify User Resource (Deprecated)

> \[!CAUTION]
>
> Twilio deprecated Notify in October 2022 and no longer supports it. Learn more about [transitioning off Notify](https://support.twilio.com/hc/en-us/articles/11746930233115-Transitioning-off-Notify).
>
> If you're starting a new project, use [Programmable Messaging](/docs/messaging) for SMS notifications. For push notifications, integrate directly with platform-specific services such as APNs for iOS or FCM for Android. If you've already built on Notify, visit the [transition guide](https://support.twilio.com/hc/en-us/articles/11746930233115-Transitioning-off-Notify) to learn about your options.

> \[!CAUTION]
>
> The **User** resource is deprecated and has been replaced by the `identity` property of the **Binding** resource.

The User resource represents a user in your application.

Because the User resource is deprecated, use the `identity` property of the Binding resource to identify a specific user.

> \[!CAUTION]
>
> The systems that process this parameter assume it does not contain PII.
>
> You should use a GUID or other pseudonymized identifier for `identity` instead of PII such as a *person's name, home address, email or phone number.* If you identify your users with PII, we recommend creating a pseudonymized identifier from their PII, for example by hashing or encrypting it, before you use it for `identity`.
