Go to your website and select Site Administration.

Select Users.

Under Accounts select User profile fields.

Click on Create a new profile field.

Provide the required fields for the profile field you have selected.

Adjust the settings to control how the custom profile field functions:
Required: Decide if users must fill in this field (e.g. during registration).
Locked: Prevent users from editing the field after it’s been set.
Unique: Ensure that no two users can have the same value (useful for things like employee IDs).
Display on sign-up page: Choose whether this field appears during account registration.
Visibility: Set who can see this field—options include the user only, administrators, or everyone.
Category: Organize the field under a specific category for better structure in the user profile.
Once configured, click Save changes.
