Faculty & Staff 2-Factor Authentication FAQ

Updated on

Have questions about 2-Factor Authentication (2FA)? Read the Frequently Asked Questions (FAQs) below.

Why is 2FA being implemented?

We are adding this security measure to help keep your personal information as safe as possible. Even if someone else knows your username and password, they will not be able to get into your account unless they also have the device that you use to authenticate.  

Check out the article Why Do We Need 2-Factor Authentication? for more information.

How often will I need to authenticate?

Each authentication lasts for 30 days. That means that unless you’ve recently cleared your history or cache, you’re using a new Internet browser, or you’re using Incognito mode, you will only have to go through the process every 30 days per device.

EXAMPLE: If you authenticated from your home computer in Google Chrome, you would be authenticated for your home computer and Google Chrome for 30 days. However, if you tried to access your BYU-Idaho account from the same computer later in the day, but used Safari instead of Google Chrome, you would need to authenticate again. You would then be authenticated for your home computer, for both Google Chrome and Safari, for 30 days. Within those 30 days, you would only need to authenticate again if you used a new device (e.g., your mobile phone) or another new browser.

Let’s say that 15 days later, you cleared your history. You would then need to authenticate again, and the 30-day period would restart.

What methods are available for me to authenticate with if I don’t have a mobile phone as my second authentication device?

If you don’t have a mobile phone, you can authenticate via a password sent to a token or via a call to a landline phone. If you do have a smartphone, however, we strongly recommend using the push notification option. Not only is this option quicker and easier, it also doesn't cost any money to the school for messaging and data rates. 

How do I get an authentication token?

You can get an authentication token by contacting the I.T. Service Desk at (208) 496-1411 or through the Live Chat bubble. A token will cost a one-time fee of $18 but will supply passcodes on an as-needed basis for as long as 2FA is utilized at BYU-Idaho (in other words, for the foreseeable future).

Will I need to authenticate from my classroom or office?

No. You will not need to authenticate as long as the device you’re authenticating from is connected to a BYU-Idaho network.

What if I get an authentication notice when I’m not trying to log in to my account?

This means that someone is trying to get into your account. Deny the login request, and immediately change your BYU-Idaho password.
