The following links are for frequently asked questions related to IslandID Two-Factor Authentication, powered by Duo Security.
Any person who has used an ATM machine to withdraw cash for a bank account has used 2-Factor authentication - you had to provide something you had (a card) and had to provide something you know (a PIN) in order to complete the transaction.
Remember: Your IslandID and password (first-level authentication) will continue to protect your account even if your phone is lost.
A. We recommend never using the "Remember me for 7 days" feature on a shared computer. You may use it on computers you are the sole user of as long as you take responsibility for the security of access to that machine.
B. Generate ten SMS passcodes ahead of time and keep them on a note in your backpack or wallet. Use this option by choosing the "Enter a Passcode" option on duo.tamucc.edu, then select "Text me new codes". You will receive a text with a 7-digit code on it. The first code begins with a 1 and the second with 2, and so forth until the the tenth code which begins with 0. Each passcode is only good one time so mark them out as you use them. Redo the process when you need more.
A. A smartphone is the best choice since it provides the greatest level of security and allows you to use the Duo Mobile App. The app generates passcodes for login and can receive push notifications for easy, one-tap authentication.
Having said that, a smartphone is not required to use the service.
You need to take into consideration the stationary nature of a landline. Even if you work almost exclusively at your desk in your office where the landline is located, you might on rare occasions need to have access to your Duo protected services from home or from a remote location.
Having said that, a hardware token is available for use instead of a phone.
If you've used the service on this phone before and cannot login, then make sure that phone is not locked. If it is unlocked, then you may need to restart the mobile device and try again.
Make sure that you're using the correct mobile device. If you're using a new device (even if you have the same phone number), then reactivate Duo Mobile for the new device. (If you're changing types of phone, such as going from an Android to an iPhone, then select the new type of phone before reactivating.)
If the service is still not working, then contact the IT Service Desk.
