If you use Slack to connect and collaborate with colleagues while you work from home or the office, you can add an extra layer of security to your account by enabling two-factor authentication (2FA) for your account.
In the event that your password is compromised, no one will be able to access your account because they will not have the second form of authentication (your phone).
Slack supports two methods to configure two-factor authentication, including using an authentication app or SMS text message. However, using the authentication app is the easiest and recommended method.
In this guide, you’ll learn the steps to enable two-factor authentication on your Slack account.
