Open **Sign In & Security**, find **Multi Factor Authentication**, and select **Set up** to pair an authenticator app or **Disable** to turn it off.

An authenticator app is the only second factor Evolve offers. There is no SMS option and there are no recovery codes, so keep access to the app you pair.

## Turn it on

1. Select your avatar, then **Settings**, then **Sign In & Security**.
2. Under **Multi Factor Authentication**, the **Authenticator App** row reads **Set up your account to receive auth code via a mobile application.**
3. Select **Set up**. The dialog **Enable two-factor Authenticator** opens.
4. Scan the QR code with your authenticator app. If the app cannot read it, use the key printed under **If your app does not recognize the QR code, type the following key:**.
5. Type the six-digit code from the app in **Type the 6-digit code here**.
6. Select **Continue**.

The row then reads **Authenticator app is enabled for this account.** From the next sign-in, Evolve asks for a code in the **Multi-factor Authentication** dialog after your password.

## Turn it off

1. Go back to **Multi Factor Authentication** on the same page.
2. Select **Disable**.

There is no confirmation step. The row returns to **Set up**.

## When you cannot change it

The row shows a badge instead of a button in three cases:

- **Required** — your Account requires an authenticator app, and the status line reads **Authenticator app setup is required before you can continue.**
- **Enabled** with the line **Authenticator app is enabled and required for this account.** — it is on and you may not turn it off.
- **Unavailable** with the line **Authenticator app is unavailable for this account.** — the method is not offered for your Account.

## If it did not work

- **Invalid code** in the dialog means the code was wrong or had already rotated. Wait for the app to show a new code and retype it.
- **Continue** stays unavailable until the code is exactly six digits.
- **Unable to start two-factor setup.** means the setup request failed. Reload the page and select **Set up** again.
- **Unable to disable two-factor authentication.** means the change was rejected. Check whether the row now reads **Authenticator app is enabled and required for this account.**, which means your Account does not allow it to be turned off.
