Adding and Managing Devices
After you have added your first device and authenticated you will be logged into your account. In order to add an additional device you must log out and log back in (or login using an Incognito/Private window). After you log in with your Swarthmore credentials, but before you authenticate with Duo you will see links on the left-hand side of the window that give you the option to add and manage devices. As a note, in order to complete the addition of another device you will have to authenticate using a device already active with Duo, so make sure it is available to you.
Why should I have more than 1 device registered?
With only one device registered to your account, you run the risk of being unable to complete your log in if that authentication device is not available to you at that time. By having multiple devices registered you can ensure that you will always have a device on hand to complete the Duo authentication process and access your account. This could be especially important if you are away from your office for a meeting, a workshop, or traveling and need to access your account. We recommend at least 2 devices, but you can add as many as you would like. You can also have multiple devices of the same type (e.g., having multiple landlines registered).
Managing Devices and Settings
With multiple devices registered to Duo for you to use for authentication, you will need a way to manage them. At login, before completing your authentication with Duo, you can choose the "My Settings & Devices" link on the left-hand side of the authentication window. You will be prompted to choose a method to authenticate, as Duo wants to make sure you are who you say you are and have the right make changes to your devices. Once you finish that authentication process you will be brought to a list of your current devices. Here you can delete devices you no longer have or wish to use, as well as rename devices to make sure they easier for you to find in your device list. You will also get the option to add new devices here if you find that a device option is missing from your list.
Directly below your list of devices is the section you will use to set your defaults. Here you will choose which device you want to be your default device (the one you are most likely to use on a daily basis) and also what you want Duo to do with that device. You will be given a few options for device actions:
- Automatically call me
- Automatically send a push
- Ask me to choose an authentication method
It is recommended that you have your Duo account set to "Ask me to choose an authentication method." This will make it easier to choose an alternative method of authentication when logging in if you happen to not have access to your default device. If you already have one of the automatic options chosen and you want to choose another authentication method or stop the authentication process to access your Settings, there will be a blue bar across the bottom with the option to cancel the current automatically sent authentication request. Once you cancel the request you can access all of your options.
You can set Duo to remember you for 15 days. This allows you to authenticate once, and then not have to do so again (on that computer/device) when logging into your account for 15 days. This option is a check box located under your authentication options on the Duo screen when logging in. If you check this option and still get prompted with the Duo screen on your next login, you may have to change your browser settings to allow it to properly save your choice.
What if I clicked “Remember me for 15 days” but I am still being asked to authenticate?
This setting must be applied to each browser you use on each computer you use. If you choose this setting, but log in later with a different browser you will have to set it again for that browser during authentication. If you are certain you chose it to remember you on both the computer and the browser you are using, then it might be a setting on the browser that is not saving your choice.
