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 no longer accepts Basic authentication (username and password) for API calls when two-factor authentication is enabled for a user. You can now only use two-factor authentication if you are authenticating with an API key. For more information, see Authentication.
SendGrid’s Two-Factor Authentication can be configured to accept a code sent to your mobile phone either via the Authy App, or an SMS message.
You may choose from 2 different verification methods when using two-factor authentication:
When authenticating via SMS message, you must have cellular service, or you will not be able to log into your account.
To set up Two-Factor Authentication:
Subusers and Teammates need to create their own Two-Factor Authentication settings in their account using the same steps.
After you create a setting for Two-Factor Authentication, log in as you normally would. If you opt to receive a text message with your authentication token, look for the text message and enter the code that you receive. If you have selected the Authy App, go to your app, and enter the generated code.
Once set up, you will always be required to use Two-Factor Authentication to perform security-restricted actions in your SendGrid account, such as logging in or changing your Two-Factor Authentication settings. When prompted, enter the 7-digit token sent to your device, or generated by the Authy App.
To disable or delete a Two-Factor Authentication setting:
