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 from the one you normally use to sign in.
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.
The Microsoft Authenticator app will run on Android and iOS based tablets and does not need a network/internet connection to generate two-step codes. The set-up process is the same as for a mobile phone.
Some alternatives are:
- Google Authenticator (iOS, Android)
- andOTP (Android)
- Authy (requires a phone number in order to sign up)
You do not need a camera on the device you are using. You can type in the secret that is displayed on the two-step set-up page after selecting I can't scan the code (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 examples are:
During the set-up process, select I can't scan the code, then note down the code in the Secret box. You can then import this secret into your chosen application and use it to generate two-step codes.
It is also possible to use the Authy service mentioned in the previous section, provided you're able to sign up for an account. Simply add a new account and enter the secret you received in the step above:
- Turn on two-step authentication
- Sign in with an authenticator app
- Sign in with a text message
- Sign in when you don't have your phone with you
- Backup verification codes
- What duration should I choose?
- Lost or stolen phones
- Use an alternative device to authenticate
