Slack 2FA: How to Set Up an Authenticator App
Slack lets you secure your account with an authenticator app. With 2FA on, each login needs a fresh 6-digit code, keeping your Slack account safe even if your password leaks.
A Slack account carries private conversations, so keeping it secure with 2FA matters. Besides an authenticator app, Slack also offers SMS text codes. An authenticator app (TOTP) is usually the best balance of security and convenience — and it's safer than SMS codes, which can be intercepted through SIM-swap attacks.

Download Authenticator App - Novaz

Scan the QR code with Authenticator App - Novaz.
Open Authenticator App - Novaz, tap add, and point your camera at the QR code Slack displays. Can't scan? Enter the setup key manually instead.
- 5
Enter the 6-digit code to confirm.
Type the code Authenticator App - Novaz generates to verify and link your Slack account.

Save a way to recover your account.
If Slack shows backup or recovery codes, store them somewhere safe, away from your phone. If it doesn't, check how Slack recovers accounts (support, an admin, or another sign-in method) before you need it.
Menu names on Slack can change — the official Slack 2FA documentation ↗ always has the exact, current path.
How to recover your Slack account
If you lose access to your authenticator and Slack gave you backup or recovery codes when you turned on 2FA, sign in with one of them; keep them somewhere safe, away from your phone. Not every service issues codes. If Slack doesn't, or you didn't save them, use Slack's account-recovery or support process (or ask your admin, for a work account) to get back in.
