For an added layer of security, turn on two-factor authentication (2FA) for your Slack account. If your password is compromised or stolen, you'll have peace of mind knowing that only you can sign in. 🔐
How 2FA works:
You’ll need access to your mobile phone when you sign in to Slack.
You'll enter a verification code and your password each time you sign in.
You can choose to send your verification code by text message or from an authentication app.
Step 1: Download and install an authentication app
Before you can set up 2FA on your account, you’ll need to download and install an authentication app on your device. Slack 2FA can be used with most Time-Based, One-Time Password (TOTP) applications. Here are a few options to get you started:
Expand Two-Factor Authentication, and click Setup Two-Factor Authentication.
Enter your password, and click SMS Text Message to receive authentication codes by text message.
Select your country from the menu, and enter your mobile phone number. Include your area and/or zone code.
Next, we'll send a 6-digit verification code to your device. Enter the code on the Slack 2FA configuration page.
To finish, select Verify Code.
You'll be sent a text message with your single-use authentication code every time you sign in to your workspace.
Note: Standard message rates apply. Check with your mobile service provider for information on fees for receiving SMS/text messages.
Use 2FA with multiple workspaces
If you're a member of more than one Slack workspace, you’ll need to set up 2FA for each account separately.
Copy and paste https://your-url.slack.com/account/settings (don't forget to add your workspace's domain) to enable 2FA for all of your accounts.
If you lose your phone or you've deleted your authentication app, you can use one of your backup codes to sign in. Use any code to sign in, but keep in mind that each code can only be used once. Your backup codes were provided at the time you set up 2FA, but you can always find them on your Account page.
Tip: Make a copy of your codes and save them someplace safe. 🔑
If you got a new phone or don't have access to your backup codes, you can ask a Workspace Owner or Admin to manually disable 2FA for your account. If you're a Workspace Owner and you can't sign in, you'll need to contact the Workspace Primary Owner to help.
Please give these instructions to a Workspace Owner or Admin to help you disable 2FA on your account:
From your desktop, click your workspace name in the top left.
Select Administration, then Manage members.
Click the three dots icon to the right of the member you'd like to manage.
Click Disable two-factor authentication.
