Alternative devices

You don't need to use a phone as your two-step device. If necessary, if you prefer not to use your phone every time you sign-in, you can use a different device to generate two-step codes. IT Services strongly recommend that you use a different, separate device to one that you normally sign-in with.

You should not use the same primary device that you sign-in to Warwick web services with as a system to generate two-step codes.

Tablets

The Google Authenticator application will run on Android and iOS based tablets. You do not need a network/internet connection. Simply install the app from your preferred app store and follow the set-up process as documented for a phone.

If you cannot install the Google Authenticator app (for example, it is not available on your preferred app store), many other applications are compatible with the same system. For example:

You do not need a camera on the device you are using, you can type in the secret which is displayed on the two-step set-up page after clicking the "I can't scan the code" link (see below).

Laptops and desktops

If you have a separate laptop that you are willing to use as a two-step device, you can install a desktop application or browser extension that is capable of generating two-step codes. Some example applications are linked below:

During the set-up process, click the "I can't scan the code" link and note down the key displayed in the dialog window. You can then import this secret into your chosen application and use it to generate codes.

It is also possible to use the Authy service discussed in the previous section, provided you are able to sign-up for an account. Simply add a new account, and type the secret you receive from single-sign on into the box:
