Manage Advanced MFA Phone usage

* * *

## What you are charged for[#](#what-you-are-charged-for)

You are charged for having the feature [Advanced Multi-Factor Authentication Phone](../../../auth/auth-mfa/phone/index.md) enabled for your project.

The Advanced MFA Phone add-on is **not** covered by the [Spend Cap](../../cost-control/index.md#spend-cap).

Additional charges apply for each SMS or WhatsApp message sent, depending on your third-party messaging provider (such as Twilio or MessageBird).

## How charges are calculated[#](#how-charges-are-calculated)

MFA Phone is charged by the hour, meaning you are charged for the exact number of hours that the feature is enabled for a project. If the feature is enabled for part of an hour, you are still charged for the full hour.

### Example[#](#example)

Your billing cycle runs from January 1 to January 31. On January 10 at 4:30 PM, you enable the MFA Phone feature for your project. At the end of the billing cycle you are billed for 512 hours.
