Set up an app for two-factor authentication

If you log in to Sigma using a username and password, you receive two-factor codes sent to your email address. If you want, you can set up an app for two-factor authentication instead.

Using an app for two-factor authentication can be more reliable than receiving codes to your email address, and provide a true second factor by requiring you to access a separate device, such as your smartphone, or application to generate the two-factor authentication code.

📘
If you do not have an app set up for two-factor authentication, or if you ask your admin to reset your authenticator app setup in Sigma, you receive two-factor codes to the email address you use to log in to Sigma.

Requirements

If you use a username and password to log in to Sigma directly, you can set up an app for two-factor authentication.

You must have an app installed on a device that you can use to generate two-factor authentication codes. For example, a smartphone with Okta Verify, Duo Mobile, Microsoft Authenticator, Google Authenticator, or a similar app installed.

Set up an app for two-factor authentication

To set up an authenticator app for two-factor authentication:

In the Sigma header, click your user avatar and select Profile.
In the Authentication section, click Enroll app for the Set up authenticator app option.
Open the authenticator app on your smartphone and scan the QR code or click Show secret () to show the secret that you can use as a setup key, then enter the key in your app.
In Sigma, enter the 6 digit code generated by your authenticator app.
Click Verify to complete the setup.

After setting up an authenticator app, you're prompted to enter a code each time you log in to Sigma. Whenever you log in, you can still choose to get a code sent to your email address instead.

Turn off app-based two-factor authentication

If you lost your device with an authenticator app installed or need to set up a new one, or otherwise want to stop using an authenticator app for two-factor codes, you can turn off your authenticator app. If you turn off app-based two-factor authentication, you instead receive two-factor codes to your email address.

To turn off app-based two-factor authentication:

In the Sigma header, click your user avatar and select Profile.
For the Set up authenticator app option, click Disable.
When prompted, click Disable.

You can also ask an admin to do this for you. For admin instructions, see Reset two-factor authenticator app.
