Frequently Asked Questions
Authentication is a means of verifying one’s identity, and two-factor authentication (2fa) is a method of establishing access to an online destination, by requiring users to provide two different types of information. One common mode of single factor authentication is the username password pair. With 2FA, users need to both provide a password and prove your identity some other way to gain access. A common 2FA method is to send a time expiring one time password, sent to a mobile device via SMS in addition to username and password.
A two factor authentication code, or otherwise referred to as OTP (one time password), is a secondary means of authentication required to get access to a user account. This is sent as a message to the number saved on the account, after the user logs in with their email and password.
You will first need to create a 2FA profile that you will use to send your 2FA codes and where you will receive your responses. Secondly, to send the 2FA code, you need to input the phone number that will receive the message. Finally, the user will send the code they receive on their device back and if it matches the code that your profile sent out, the verification was successful and the customer has access to their account.
The Verify component of the Mission Control Portal is currently in development but will be live mid October. Once live, you will be able to create a Verify profile and a verification code within the section of the portal.
You can access the API in our Mission Control Portal and follow the simple steps under the Verify section. Alternatively, you can follow the developer docs to start sending 2FA codes via our API implementation.

Most of our users implement two-factor authentication to improve the security on their customers’ accounts. 2FA helps achieve this goal by requiring users to provide another method of identity validation in addition to username and password.
