How to enable 2FA for your Slack account
Updated June 5, 2026
A step-by-step guide on how to set up two-factor authentication (2FA) for your Slack account using Authenticator App. With 2FA enabled, signing in requires both your password and a temporary verification code — keeping your account safe even if your password is stolen.
Download Authenticator App
First, download the Authenticator ℠ App on your Apple device. Click the button below or scan the QR code with your iPhone camera.
Get the Authenticator ℠ App
Scan the QR codes from Slack and generate secure one-time codes.
Sign in and open your Account settings
Sign in to your Slack workspace in a web browser and go to your Account page at my.slack.com/account/settings.
Expand Two-factor Authentication
Next to "Two-factor Authentication," click Expand to reveal the setup options.
Start the setup
Click Set Up Two-Factor Authentication, then enter your password to continue.
Choose the authenticator app option
Click Use an app to set up two-factor authentication using a TOTP authenticator app rather than text message.
Scan the QR code with your Authenticator App
Open the Authenticator App on your iPhone, tap the + button, and scan the QR code shown by Slack. If you can't scan it, choose to enter the code by hand using the secret key Slack displays.
Enter the 6-digit code and verify
Back on Slack's 2FA configuration page, type the 6-digit verification code generated by your authenticator app, then click Verify Code to confirm.
Save your backup codes
Slack provides backup codes when you set up 2FA. Save them somewhere safe, as each code can be used only once to sign in if you lose access to your authenticator app. You can always find them again on your Account page.
Backup & recovery
Slack provides single-use backup codes at the time you set up 2FA. If you lose your phone or delete your authenticator app, you can use one of these backup codes to sign in (each code works only once). Your backup codes can always be found again on your Account page (my.slack.com/account/settings).
That's it — your Slack account is now protected with two-factor authentication. If you have any issues during setup, visit the official Slack help page. Stay safe!
