# Configuring the phone number attribute in PingOne

If you are using PingOne as your identity provider (IdP) and want to enable backup authentication or pre-populate or restrict registration data, you must first define the phone number attribute in the PingOne directory.

## About this task

For more information, see [Configuring backup authentication methods](pid_configuring_backup_authentication_methods.html) and [Pre-populating or restricting user registration data](pid_prepopulating_or_restricting_user_registration_data.html).

## Steps

1. In the PingID admin portal, go to **SETUP → Directory → Attributes**. ![A screen capture of the Attributes tab.](_images/bsq1564020627347.png)

2. If the **phoneNumbers** attribute is not listed, click **Add Attribute** and then select the **phoneNumbers** attribute. Click **Add**. ![A screen capture of the Add Attribute modal.](_images/gen1564020628098.png)
