Does US Internal Revenue Service support 2FA?

How to enable 2FA on US Internal Revenue Service

1. Sign in to your US Internal Revenue Service account.
2. Open Account settings → Security (the exact path varies; see the official docs link above).
3. Choose your preferred method from the list — TOTP and hardware keys are the recommended options.
4. For hardware keys: insert your key when prompted and tap to enroll. Register at least two keys per account so loss of one doesn't lock you out.
5. Save the recovery codes somewhere safe — they're your last resort if you lose your authenticator and your hardware keys.

Sharing US Internal Revenue Service 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 US Internal Revenue Service access with your team:

1. In Kaito, go to Tokens → New and add the US Internal Revenue Service 2FA seed (or scan the QR).
2. Permission the token to a group: code-only for most teammates, full-seed only for the admins who would handle rotation.
3. US Internal Revenue Service only supports SMS 2FA. Provision a Kaito SMS number and use the service's "phone number on file" setting to point verifications at it. Codes will stream to whoever you've authorized.
4. Stream the audit log to your SIEM if you want a complete record of which team members generated codes for US Internal Revenue Service and when.

US Internal Revenue Service permits shared access in their terms of service.
