What is Two-Factor Authentication?
{% endanchor %}

Two-factor authentication, commonly referred to as multi-factor authentication, allows you to make your SendGrid account more secure by requiring authentication beyond a simple username and password when logging in.

SendGrid’s Two-Factor Authentication can be configured to accept a code sent to your mobile phone either via the the [Authy App](https://www.authy.com/app/mobile/), or an SMS message.
