MoEngage protects your end users' Personally Identifiable Information (PII). As an admin, you can mask any user attribute or event attribute, regardless of the encryption. Additionally, when you encrypt a user attribute or event attribute marked as PII, MoEngage automatically masks it for you.

Mask the User Attributes 

Perform the following steps to mask user attributes:

1. On the left navigation menu of the MoEngage dashboard, click Settings > Data management.
2. On the Data management page, click the User attributes tab.
3. Search for the desired user attribute and click the ellipsis icon against that attribute.
4. Click Edit attribute.
5. On the Edit attribute details side drawer, turn on the Mask attribute toggle to ensure sensitive data is concealed from other users within your workspace.
6. Click Save. 

Mask the Event Attributes

1. On the left navigation menu of the MoEngage dashboard, click Settings > Data management.
2. On the Data management page, click the Events tab.
3. Search for the event and then expand the event to view the event attributes under that. Click the ellipsis against that attribute.
4. Click Edit attribute.
5. On the Edit attribute details side drawer, turn on the Mask attribute toggle. Turning on this toggle hides the PII from other users in your workspace.
6. Click Save and Continue.

View Masked User and Event Attributes

After you mask user or event attributes, users in your workspace can view them on the following pages, tabs, and dialog boxes of the MoEngage UI, depending on their assigned roles and permissions.

User Search Box

You can view masked user or event attributes on the Create Segment page. Search for a user in the Search user by ID, Email, Mobile No, or MoEngage ID search box.

Accessibility to masked attributes depends on your assigned role. If you have the permission to view these attributes, you can see the real values of masked attributes. Otherwise, these appear as Private on the Name column and --- (masked).

Show Users Window

You can view masked user or event attributes on the Showing users after segmentation page. Perform the following steps to view the Showing users after segmentation page:

1. Click Show count while creating a segment on the Create Segment page, and expand the Query results.
2. On the Sample users section, click Show more.
3. The Showing users after segmentation page displays all the users after segmentation.

User Exports Window

You can view masked user or event attributes on the Export users data dialog box. MoEngage disables masked user attributes on the Export users data dialog box based on your role. This means if masking is not accessible for your role, you cannot export masked attributes using the Export users option on the Create Segment page.

1. Click Show count while creating a segment on the Create Segment page, and expand the Query results.

   Accessibility to masked attributes depends on your assigned role. If you have the permission to view these attributes, you can see the real values of masked attributes. Otherwise, these appear as Private.

You can also access the User Profile page using the Search user by ID, Email, Mobile No, or MoEngage ID search box on the Create Segment page.  Search for the user in the search box and click the name of the desired user.

User Info Tab

Perform the following steps to view the masked attributes on the User Info tab:

1. Click Show count while creating a segment on the Create Segment page, and expand the Query results.
2. On the Sample users section, select the desired user to view their user profile.
3. On the User Profile, click the User info tab, and then click User Properties.
   Accessibility to masked attributes depends on your assigned role. If you have the permission to view these attributes, you can see the real values of masked attributes. Otherwise, these appear as Private.
   

Activity Info Tab

Perform the following steps to view the masked attributes on the Activity Info tab:

1. Click Show count while creating a segment on the Create Segment page, and expand the Query results.
2. On the Sample users section, select the desired user to view their user profile.

Value Suggestions

Visibility of masked value suggestions on the Segmentation and Analytics page depends on your role. 
These suggestions are disabled for roles without masking access. However, roles with masking permissions can see the real values behind the masked suggestions.

Split by or Compare by in Analytics Pages

On Behavior, Funnel, and Retention pages of Analyze, when you select the attributes for the Split by or Compare by functionalities, attribute visibility depends on your role. If masking is not accessible for your role, masked attributes are disabled. If accessible, you can view the actual values of the masked attributes.

Test Users

You can view the list of test users and their masked PII by navigating to Test & Debug > Test users from the left navigation menu of the MoEngage UI. Accessibility to masked attributes depends on your assigned role. If you have the permission to view these attributes, you can see the real values of masked attributes. Otherwise, these appear as Private and --- (masked).

Personalization Preview

All the masked user attributes are shown as XXXXXXXXXX on the personalization preview in the campaign creation pages. The following image displays the preview of masked PII attributes during the SMS campaign creation. For more information, refer to PII Masking on Personalised Preview.

Non-Dashboard Functionality

Features outside the MoEngage UI do not support PII masking. Hence, PII masking is not available for Open Analytics, S3 Exports, and MoEngage Streams.

These features are not available by default, require manual enablement, and are enabled on request. You can provide your team with access to these features as per your security and data needs.
