How does two step login work with Okta? How do I login?

Question

How does two step login work with Okta?

Answer

Two step authentication reduces the ability of a hacker to access your account and data, by requiring two methods to verify you:

1. The NetID and password that you know
2. A phone, tablet device or Yubikey that you have possession of

A hacker may gain access to your NetID and password, but it will be more difficult for them to access that device as well.

So how will I login?

1. When you login to an ND service protected by two step (e.g. Gmail, Sakai, Box, and many others), you will enter your NetID and password.
2. If the system needs to verify your login, you will then be presented with a second screen allowing you to select which device and method you wish to use as your "second factor". That screen will look something like:
   
3. If you are using a computer or device that is NOT shared with others, we recommend you check the box, Do not challenge me on this device for the next 30 days
   1. This will store information on that device or browser so that you won't be prompted for Two Step again until 30 days have elapsed.
   2. Note: Do NOT check this box on a shared computer such as a classroom or lab, as it may allow others using that computer to access your account.
4. If you wish to use a different factor that you've enrolled, click the arrow to the right of the Okta logo to display the additional options:
   
5. Select the option you wish to use.
6. Depending which device you selected, you will receive a notification on that device that you will need to respond to.
