# Registering to Payhawk with an SMS

The Payhawk Administrators at your company may have decided to invite you to Payhawk with an SMS.

In such cases, you need to [download the Payhawk Mobile App on your mobile device](/help/activating-your-personal-payhawk-account) and, then, follow the steps:

1. Open the SMS and tap the registration link. You will be redirected to the Payhawk Mobile App (if already installed), or you'll be prompted to install the Payhawk Mobile App (if not yet installed).
2. Create a password for your account and tap **Continue**. [See password requirements](/help/registering-to-payhawk-with-an-email-invite).
3. Confirm (repeat) the password for your account and tap **Confirm**.

4. If you have Payhawk cards already assigned to you, on the next screen, you will need to create a four-digit security code, which will protect the usage of your virtual and physical cards.
5. You will automatically be redirected to the next screen. Confirm (repeat) the security code. You can now start using Payhawk.

> [!WARNING]
> Ensure the mobile phone number linked to your Payhawk account is always up to date - if necessary, you can [update your phone number](/help/updating-your-phone-number).
