**Description**

Notification indicates current logged in user. Once a user has been authenticated by entering the passcode an icon appears in the Title bar. This icon indicates the user is logged in.

When `Merchant.UserAuthAlwaysAuthenticate` flag is set to true, the notification icon is no longer displayed, indicating that the user must authenticate every time when accessing a passcode protected function.

\
**Configuration Parameters**

`Merchant.UserAuthAlwaysAuthenticate` - Enables the terminal to always prompt for passcode each time a terminal activity that requires authentication is encountered. When disabled, the terminal will instead check if a user is logged into the terminal and use that status to determine if authentication is still required or already granted.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.verifone.com/functional-specification/user_auth_unlock_screen.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
