Before using this method, be sure that you can receive text messages. Carrier rates may apply.

{% warning %}

Warning: We strongly recommend using a TOTP application for two-factor authentication instead of SMS, and security keys as backup methods instead of SMS. {% data variables.product.product_name %} doesn't support sending SMS messages to phones in every country. Before configuring authentication via text message, review the list of countries where {% data variables.product.product_name %} supports authentication via SMS. For more information, see "AUTOTITLE."
