# Set up MFA

> Protect your K16 account with a time-based authenticator code.

K16 supports time-based one-time password authentication through compatible authenticator apps. Your workspace or role may require MFA.

<Warning>
  Treat the setup key and QR code like a password. Do not paste either value into support messages,
  screenshots, or documentation.
</Warning>

<Steps>
  <Step title="Open Security settings">
    Open your account menu, select **Settings**, then select **Security**.
  </Step>

  <Step title="Start setup">
    In **Two-Factor Authentication**, select **Set up MFA** or **Add authenticator**.
  </Step>

  <Step title="Add K16 to your authenticator">
    Scan the QR code or enter the setup key in your authenticator app.
  </Step>

  <Step title="Verify a current code">
    Enter the six-digit code shown by your authenticator and finish setup. Wait for the success
    confirmation before leaving the page.
  </Step>
</Steps>

If **Security** asks you to sign in again, your K16 session is still active but the authentication credential used to manage MFA has expired. Sign out, sign in with your email and password, and return to **Security**.

To replace an existing authenticator, select **Reconfigure**. K16 requires you to verify your identity before showing a new setup key.
