# Metafields
Metafields are custom fields that you can use to store additional information about your users. They are administration-only fields that allow you to add metadata to hold IDs and make associations with your own systems. Scute supports 7 data types for metafields: string, integer, date, email, phone, url, and boolean.
Metafields are not used in login forms for collecting extra data from users. Instead, they serve as a way to store and retrieve meta information that you can process in your application during authentication, signup, and other user-related operations.
## Metafield Verification
You can now verify metafield values using OTP codes sent to the specified identifier. This is particularly useful for:
* Verifying email or phone metafields before important operations
* Confirming ownership of contact information stored in metafields
* Adding an extra layer of security for sensitive metafield updates
See the [User Identifier Verification guide](/docs/verification/user-identifier-verification) for details on implementing metafield verification in your application.
Go to [control.scute.io](https://control.scute.io), select your app and click on the "Metafields" tab. Enter the field name, select the data type and click on the "Add +" button to create a new metafield.
