How to enable 2FA with email in Ozeki SMS Gateway

This article shows you how to enable two-factor authentication (2FA) in Ozeki SMS Gateway using an email address. This method is a convenient choice for users who would rather receive a one-time code in their inbox than install a separate authenticator app or rely on SMS. The guide first shows you how to set up an email client, since this is required for the system to be able to deliver the verification code, then walks you through enabling email based 2FA and logging in with it.

What is two-factor authentication?

Two-factor authentication (2FA) is a security method that requires users to provide two different forms of identification before they can access an account. In Ozeki SMS Gateway, 2FA combines your regular login credentials with a temporary 6-digit code sent to your email address. This means that even if someone obtains your password, they will not be able to log in without also having access to that email inbox.

Steps to follow

We assume Ozeki SMS Gateway is already installed on your system. You will also need an email client that can be used to send the verification code, you can check out our guides here: E-mail to SMS forwarding.
