HOW TO ENABLE 2FA ON YOUR SLACK ACCOUNT
Slack has very good step by step instructions already built on their website for enabling 2FA on your account, and the process for logging in with it, available here: https://slack.com/help/articles/204509068-Set-up-two-factor-authentication-Set-up-two-factor-authentication
*Note that if you have DUO already installed on your smartphone, you can skip step 1, and proceed directly to step 2 as shown here:
1. Sign into the appropriate workspace and visit your Account page at my.slack.com/account/settings
2. Next to Two-factor Authentication, click Expand. Then, click Set Up Two-Factor Authentication.
3. Enter your password and click Use an app to retrieve authentication codes from the authentication app on your device.
4. Add a new account. In most apps, you can do this by tapping the + icon.
5. Scan the QR code by using your device's camera. If you prefer, you can choose to enter the code by hand.
6. On Slack's 2FA configuration page, enter the 6-digit verification code that your authentication app generates.
7. To finish, press Verify Code.
After you’ve configured 2FA and logged in once with your password and the verification code, you do not have to enter the verification code again when opening the app, unless you fully log out of your account. Simply closing the app does not necessitate entering a 2FA verification code when re-opening Slack.
*Note – If you are a member of multiple Slack workspaces, you will need to log back into those workspaces, because you are logged out of your Slack account during this process.
Enabling 2FA across multiple workspaces
This 2FA change only applies to the workspace you are logged into and making the change for. Your other slack workspaces will maintain the same sign-in security they previously had configured, unless you also update them (see the above help article and scroll to the section titled “Use 2FA with multiple workspaces”, if you’d like instructions on enabling 2FA across all workspaces you are a member of).
Forgot the names of slack workspaces?
If you forget the names of any slack workspaces you were previously logged in to, please go to https://slack.com/get-started#/find , which will assist in reconnecting you to any workspaces associated with your account.
