There are two use cases for which your phone number is required:

  • It allows us to quickly get in touch with you if we suspect a fraudulent use of your account
  • It will be asked in order to set up the 2FA Validation.
  • It makes 3-D Secure protocol possible (i.e. the sending of a confirmation code for online purchases).

For these reasons, it is very important that you make sure that your contact details are always up-to-date in your user profile (learn how to update your information).
