Manage user properties

Amplitude’s Govern feature makes it easy for you to quickly manage and modify your user properties, in basically the same way as your events and event properties.

You can find a list of all the user properties you've instrumented for a given project, along with some basic information on each, in the User Properties tab:

• The status of the user property
• The property's visibility
• The property's 30 day volume
• The property's 30 day queries count
• The date the property was most recently seen by Amplitude

You can view the details for a property by clicking its name. This will open the property details panel, which displays the information listed above (except for the property's block status) and a list of charts that include the property.

You can find a specific property using the search bar, or by using the filter drop-down next to it.

Change a user property's visibility status

You can change a single property's visibility status simply by clicking the Visibility drop-down for the property and selecting its new status.

Setting a property's visibility status to hidden is helpful for properties you may want to track but do not want to appear on the dashboard in any charts. Marking a property as hidden does not delete the event's raw data.

To change the visibility status for multiple properties at once, follow these steps:

1. Find the user property whose status you want to change and click the checkbox next to its name.
2. Click the Visibility drop-down.
3. Select the event's new status.

Change a user property's data type

You can edit the data type of a user property—for example, from a string to a Boolean. This can be useful as your data and analysis needs shift and expand over time.

To edit the data type of a user property, follow these steps:

1. Find the user property whose data type you want to change and click the checkbox next to its name.
2. Click Edit Data Type.
3. Select the property's new data type and add any required specifications.

Merge two or more user properties

Just like with event properties, you can combine multiple user properties into a single property using the Transform feature. 

NOTE: When you merge two or more properties into a single new property, the original properties will no longer be listed on the User Properties tab. Instead, only the single new property will be displayed. However, the original properties will appear on the property details tab of the new property.

To merge user properties, follow these steps:

1. Find the user properties you want to merge and click the checkbox next to their names.
2. From the Transform drop-down, select Merge.
3. Type in the name of the new, combined property and click Next.
4. A confirmation modal will appear. If you still wish to merge these values, click Merge.

Block and unblock user properties

You can prevent Amplitude from collecting data on a specific user property by blocking it. When you block a property, Amplitude will immediately stop processing data for it until you decide to unblock it.

To block a user property, follow these steps:

1. Find the property you want to block and click the checkbox next to its name.
2. Click Block.
3. A confirmation modal will appear. If you are sure you still want to block the property, click Block.
4. To unblock a blocked property, follow steps 1-3 and click Unblock instead of Block.

Manage the block list

The block list is a list of all the event types and user properties you are currently blocking for a specific project, as well as a historical view of previously blocked event types and user properties. The block list will also show you event types that have been deleted from your project.

You can reach the block list from Govern's Advanced tab.

You can also block event types and properties from within the block list itself. To do so, click + Add a Data Filter, and in the modal that follows, set up your parameters for the events or properties you want Amplitude to block. 

Delete and undelete user properties

To delete user properties you no longer need, follow these steps:

1. Find the property or properties you want to delete and click the checkboxes next to their names.
2. Click Delete.
3. A verification modal will appear, instructing you to type in a confirmation phrase to continue with the deletion process. Type it in the text box and click Delete (#) Property.

If you change your mind after you've deleted a property, you can easily undelete it. To do so, follow these steps:

1. From the status filter drop-down, select Deleted. This will limit the User Properties tab to displaying only your deleted events.
2. Find the property or properties you want to undelete and click the checkboxes next to their names.
3. Click Undelete.
