# Open the Notification Center

{% hint style="info" %}
**Who can use this feature?**

* Workspace **Owners**, **Super Admins**, **Admins**, **Users**, **Login-Only**, and **Guest Users**
* Only supported using the Cerby mobile app
  {% endhint %}

The Notification Center is an in-app inbox that collects security events requiring your attention. You can open it at any time to review new device logins, identity confirmation requests, trusted device requests, account sharing notifications, and one-time password (OTP) codes.

To open the Notification Center, complete the following steps:

1. Open the Cerby mobile app on your mobile phone.
2. Log in to your [Cerby](https://app.cerby.com/) workspace.
3. Tap the bell icon in the upper-right corner of the screen. The **Notification Center** is displayed, with the most recent events at the top.

Notifications are grouped by date into two sections: **TODAY** and **LAST 7 DAYS**. Unread notifications appear with a highlighted indicator. Scroll down to load older notifications. When no notifications are available, the Notification Center displays a message indicating there is nothing to show yet. If an error occurs loading notifications, an error message is displayed with a **Retry** button.

{% hint style="info" %}
**NOTE:** The unread badge on the bell icon reflects notifications from the past seven days only. Notifications older than seven days do not affect the badge count.
{% endhint %}

## Notification types

The Notification Center displays the following notification types:

| Notification type           | Description                                                               | Action required                                 |
| --------------------------- | ------------------------------------------------------------------------- | ----------------------------------------------- |
| **Identity confirmation**   | Cerby needs to verify your identity before completing a sensitive action. | Tap **Approve** or **Deny**.                    |
| **Trusted device request**  | A new device has requested approval to join your trusted device list.     | Tap **Approve** or **Deny**.                    |
| **New device login**        | Your account was accessed from an unrecognized device.                    | None.                                           |
| **New location login**      | Your account was accessed from an unrecognized location.                  | None.                                           |
| **Account shared with you** | Another user has shared an account with you.                              | None. Tap the notification to open the account. |
| **OTP received**            | A one-time password was delivered for an account action.                  | View the code in the notification.              |

### Expiration deadlines

Identity confirmation and trusted device requests have a limited response window. When the window closes, the request expires and you can no longer approve or deny it.

The following response windows apply:

* **Identity confirmation requests:** Three minutes from the moment the request was created.
* **Trusted device requests:** Five minutes from the moment the request was created.

When a request expires, the action buttons are no longer active. The notification remains visible so you can see that the request occurred. To restart an expired flow, return to the action that originally triggered it.

## 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://help.cerby.com/cerby-mobile-app/app-customization/use-the-notification-center/open-the-notification-center.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.
