Warning
We strongly recommend using a TOTP application for two-factor authentication instead of SMS, and using security keys as backup methods instead of SMS. SMS is susceptible to interception, does not provide resistance against phishing attacks, has unreliable deliverability, and is not supported in all countries. Before configuring authentication via text message, review the list of countries where {% data variables.product.github %} supports authentication via SMS. For more information, see AUTOTITLE.
