How to enable 2FA on Slack
- Sign in to your Slack account.
- Open Account settings → Security (the exact path varies; see the official docs link above).
- Choose your preferred method from the list — TOTP and hardware keys are the recommended options.
- For TOTP: scan the QR code with Kaito or your authenticator app of choice. Verify the first 6-digit code before saving.
- Save the recovery codes somewhere safe — they're your last resort if you lose your authenticator and your hardware keys.
Sharing Slack 2FA with a team (with Kaito)
Kaito gives you a vault for shared TOTP and a real-time inbox for shared SMS, with per-token group permissions and an audit log on every code view. To share Slack access with your team:
- In Kaito, go to Tokens → New and add the Slack 2FA seed (or scan the QR).
- Permission the token to a group:
code-onlyfor most teammates,full-seedonly for the admins who would handle rotation. - Stream the audit log to your SIEM if you want a complete record of which team members generated codes for Slack and when.
Slack permits shared access in their terms of service.
