How to Add Two-Factor Authentication to Your Slack Account

Slack is a team collaboration tool that is continuously growing in popularity. And if you want to make sure your team’s collaboration data (secrets of world domination) is better protected, add an extra layer of security by enabling Two-Factor Authentication (2FA).

Add Two-Factor Authentication (2FA) to Slack

Like most things with Slack, enabling 2FA is straightforward. Start by logging into your Slack account and go to Settings and click Setup Two-Factor Authentication.

Next you’ll need to choose a method to receive your authentication codes – either via a text message to your phone or using an app like Google Authenticator.

In this example, I’m using the SMS text message option, type in your phone number.

3 enter phone number

When you receive your authentication code, type it in and click Verify Code and Enable.

4 enter verification code

The next thing you should do is print out 2FA backup codes in case you were to lose your authentication device. Personally, I print them to a PDF and store the document 0n an encrypted drive.

Log out of you Slack account and log back in.

This time, you’ll need to enter in the 2FA authentication code you receive. Type it in and you should be good to go. You’ll have peace of mind knowing that your team(s) data has an extra layer of security. I recommend that you have everyone on your team enable 2FA on Slack as well.

Wrapping Up

We’ve been preaching about the importance of adding the extra layer of security of 2FA to all of your online accounts that support it.

Enabling 2FA requires a couple of extra steps than just typing in a password. But keep in mind that convenience is the enemy of security!
