# Turn on two-factor authentication

> A code from your phone every time you sign in. Even if someone finds out your password, they can't get in without it.

export const Artigo = ({titulo, href, children}) => <a className="lista-artigos-item" href={href}>
    <span className="lista-artigos-texto">
      <span className="lista-artigos-nome">{titulo}</span>
      {children ? <span className="lista-artigos-desc">{children}</span> : null}
    </span>
    <svg className="lista-artigos-seta" viewBox="0 0 24 24" width="18" height="18" aria-hidden="true">
      <path d="M9 6l6 6-6 6" fill="none" stroke="currentColor" strokeWidth="2" strokeLinecap="round" strokeLinejoin="round" />
    </svg>
  </a>;

export const Lista = ({titulo, children}) => <div className="lista-artigos">
    {titulo ? <p className="lista-artigos-titulo">{titulo}</p> : null}
    <div className="lista-artigos-itens">{children}</div>
  </div>;

With two-factor authentication, the sign-in screen asks for your password and then a six-digit code generated by an authenticator app on your phone. It's all found in **Configurações > Pessoal > Segurança** (Settings > Personal > Security), in the **Autenticação em dois fatores** (Two-factor authentication) card.

<Note>
  The Tartini interface is in Portuguese. Screen and button names appear here exactly as on screen, with the translation in parentheses.
</Note>

<Note>
  When the company requires the feature, Tartini asks for the setup right at sign-in, on the **Proteja sua conta** (Protect your account) screen, and the **Desativar** (Deactivate) button doesn't appear.
</Note>

## Turn it on

By default, the feature is off. You need an authenticator app installed on your phone, such as Google Authenticator, Authy, or 1Password.

<Steps>
  <Step title="Confirm your password">
    In the card, click **Ativar** (Activate). Type your **Senha atual** (Current password) and click **Continuar** (Continue).
  </Step>

  <Step title="Scan the code">
    Open the authenticator app and scan the code on the screen. If you can't scan it, click copy next to the key under **Digite esta chave manualmente no app** (Enter this key manually in the app) and paste it into the app.
  </Step>

  <Step title="Confirm with the first code">
    Type the number the app shows into **Código de 6 dígitos do app** (6-digit code from the app) and click **Ativar** (Activate).
  </Step>

  <Step title="Save the recovery codes">
    The screen shows the codes only once. Use **Copiar** (Copy) or **Baixar .txt** (Download .txt), keep them somewhere safe, check **Guardei meus códigos de recuperação em um lugar seguro.** (I've saved my recovery codes somewhere safe.), and click **Concluir** (Finish).
  </Step>
</Steps>

Done: the card shows **Ativa** (Active) and the date. On the next sign-in, after the password, the screen asks for the code.

<Warning>
  Each recovery code works in place of the app's code only once. Without your phone and without the codes, you can't get into the account.
</Warning>

***

## Switch apps or phones

Click **Trocar app** (Switch app). The wizard asks for your password and a code from the current app (or a recovery code), shows a new code to scan in the new app, and generates new recovery codes. The old ones stop working. The old app keeps working until you click **Confirmar troca** (Confirm switch).

***

## Generate new recovery codes

Click **Novos códigos** (New codes), confirm your password and a code from the app, and click **Gerar** (Generate). The previous codes stop working. The card shows how many codes remain.

***

## Turn it off

Click **Desativar** (Deactivate), confirm with your **Senha atual** (Current password) and a **Código** (Code) from the app (or a recovery code), and click **Desativar** (Deactivate). The account goes back to being protected by the password alone.

<Note>
  The **Desativar** (Deactivate) button doesn't appear when the company requires the feature. In that case the card shows "Sua empresa exige autenticação em dois fatores." (Your company requires two-factor authentication.)
</Note>

## FAQ

<AccordionGroup>
  <Accordion title="I lost my phone.">
    At sign-in, click **Usar um código de recuperação** (Use a recovery code) and type one of the codes you saved. Afterward, in Security, use **Trocar app** (Switch app) to register your new phone.
  </Accordion>

  <Accordion title="I closed the screen without saving the codes.">
    They're not shown again. Generate new ones in **Novos códigos** (New codes).
  </Accordion>

  <Accordion title="The app's code is rejected.">
    Check your phone's clock: the app generates the code from it. A clock that's off invalidates the codes.
  </Accordion>
