# Manage multi-factor authentication

> Enroll in or remove multi-factor authentication for your Servinix login, including authenticator app setup and recovery options for lost devices.

# Manage multi-factor authentication

Enable multi-factor authentication (MFA) to add a second verification step to your Servinix login. When MFA is active, signing in requires both your password and a one-time passcode (OTP) delivered to your registered contact method.

## Before you start

* MFA is applied per user account, not organization-wide.
* The OTP is sent as part of the login flow — no authenticator app is required.
* You need access to the contact method (email or phone) registered on your account to complete MFA challenges.

## How MFA works at sign-in

When MFA is enabled, the login sequence has two stages:

1. **Password stage** — Enter your email and password as normal. The server returns an `mfa_token` instead of a full access token.
2. **OTP stage** — Servinix sends a one-time passcode to your registered contact. Enter the OTP on the verification screen. A successful OTP submission returns your access token and completes sign-in.

This two-stage flow applies to both the web portal and the Servinix Go mobile app.

## Enable MFA

Contact your Servinix account administrator or Servinix Support to request MFA enrollment for your user account. The support team will confirm your registered contact method and enable the OTP challenge on your next login.

## Disable MFA

To remove MFA from your account, contact Servinix Support and verify your identity. Support will disable the OTP challenge so your account returns to password-only login.

## Result / verify

After MFA is enabled, sign out and sign back in. You should see a second screen prompting for a one-time passcode after you enter your password. If the OTP screen does not appear, MFA is not yet active — contact Servinix Support.

## Troubleshooting

**OTP not received** — Check your spam folder (for email OTPs) or confirm your phone number is correct. Wait 30 seconds before requesting a new code.

**OTP rejected** — Codes expire quickly. Request a fresh code and enter it immediately.

**Locked out** — See [Can't sign in](/account-billing/account-troubleshooting/cant-sign-in) or contact Servinix Support for account recovery.
