<\/p>\nMulti-factor authentication (MFA) adds a second layer of security to your online accounts. Verifying your identity using a second factor (like your phone or other mobile device) prevents anyone but you from logging in, even if they know your password.<\/p>\n
<\/p>\n
\nOnce you’ve enrolled in Duo you’re ready to go: You’ll login as usual with your username and password, and then use your device to verify that it’s you. Your administrator can set up the system to do this via SMS, voice call, one-time passcode, the Duo Mobile smartphone app, and so on.<\/p>\n
Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked \u2014 you might not even know someone is accessing your account.<\/p>\n
Two-factor authentication adds a second layer of security, keeping your account secure even if your password is compromised. With Duo Push, you’ll be alerted right away (on your phone) if someone is trying to log in as you.<\/p>\n
This second factor of authentication is separate and independent from your username and password \u2014 Duo never sees your password.<\/p>\n
\nClick your device platform to learn more:<\/p>\n
iOS phones and tablets<\/a> <\/p>\n <\/P> Yes and Duo allows you to remember a device for 30 days. You can approve any computer that you commonly use and will not be required to provide two-factor authentication confirmation until next month. For example, if you have a desktop and a laptop, you can approve both computers as trusted devices and not have to confirm your identity with a phone until the following month.<\/p>\n <\/div>\n<\/div>\n You are encouraged to set up Duo on more than one phone in case you forget a phone at home or are not at your office phone. When you are doing your initial setup, you may add as many phones as you like (landline and\/or mobile). After that, when you are logging in you can choose which line Duo will send the authentication request to (via smart phone app, SMS text message, or phone call depending on what you chose).<\/p>\n <\/div>\n<\/div>\n Yes, you can use the Manage Devices<\/strong><\/a> feature to add, remove, or change the devices that Duo can use to verify who you are. Note that, when an administrator adds your device, you will not need to go through the setup screen – we will send you the needed codes directly from Duo Security.<\/p>\n <\/div>\n<\/div>\n If you get a new phone, even if the Duo app is restored from a cloud backup, it will lose its association with your account. If the phone number of your new phone is the same, you can still authenticate using the phone call or sms option, but the push option will not work until re-activated.<\/p>\n You can re-activate your new phone with the Manage devices option. First, ensure that you still have access to any of the phone numbers enrolled in Duo. Set the authentication option to Phone Call and then select Manage devices. The phone you chose should ring, and you will need to answer, and hit any key to authenticate. From here, you can select the phone number of your new phone (assuming it\u2019s the same phone number) and under Actions, select Activate Duo Mobile. This will prompt you to scan in a new QR code from the Duo app. If you have difficulties with this process, you can submit a ticket to the IT Help Center<\/a> or call for immediate assistance – 617-353-4357.<\/p>\n <\/div>\n<\/div>\n The Duo smart phone app is designed to work internationally. If you install the app, it can generate the required code without need of either a telephone signal or data plan, and it can do this anywhere in the world. If you have a signal and data plan, the app makes two-factor authentication as easy as a pushing a single button, but if you don\u2019t have one of those two things, you can use the app to generate a six digit code and enter that manually.<\/p>\n <\/div>\n<\/div>\n The “Remember your device for 30 days” option uses a persistent cookie. If you clear cookies after you log off of the browser, the device will not be remembered and you will have to confirm your identity again when logging in.<\/p>\n <\/div>\n<\/div>\n You can contact the IT Help Center<\/a>. They will verify your identity and provide a temporary passcode. We encourage you to then go into manage devices and add an additional phone.<\/p>\n <\/div>\n<\/div>\n Contact the IT Help Center<\/a> immediately and we will lock your Duo account to prevent malicious activity.<\/p>\n <\/div>\n<\/div>\n To resolve this issue:<\/strong> <\/p>\n Disabling Content Restrictions<\/Strong><\/p>\n iOS 12 or newer<\/Strong><\/p>\n Note that if you are opening Screen Time for the first time and haven’t set up the feature, you will be prompted to set up the phone either for yourself or a child and will have the option to set a passcode.<\/p>\n iOS 11 or older<\/Strong><\/p>\n macOS 10.15 (Catalina) or higher<\/Strong><\/p>\n <\/div>\n<\/div>\n Logging in with Duo requires that JavaScript is enabled. If it is not, your attempt to log in will fail and your screen will look like this:<\/p>\n If you encounter this issue, disable any JavaScript blocking plugins or browser settings (or include an exception for scripts from duosecurity.com) and attempt to log in again.<\/p>\n <\/div>\n<\/div>\n The Duo smart phone app provides options that work without a data plan or even a connection, if necessary. The app can generate the required code without need of either a telephone signal or data plan, and it can do so anywhere in the world. If you have a signal and data plan, the app makes two-factor authentication as easy as a pushing a single button.<\/p>\n <\/div>\n<\/div>\n You can also use a tablet to access Duo, or purchase a Yubikey. Yes, everyone at the University is required to use Duo MFA.<\/p>\n <\/div>\n<\/div>\n Unfortunately, experience has shown that people are not as good at recognizing malicious email as you might think. Every day, members of the BU community fall prey to these kinds of scams. We have to take steps to ensure that we are more than just a single click away from having our paycheck stolen or becoming a victim of identity theft.<\/p>\n <\/div>\n<\/div>\n We encourage you to contact us with feedback, or with questions or concerns about the project in general. The Vice President of Information Services & Technology and the Information Security & Business Continuity governance committee for IS&T can be reached directly at duo@bu.edu<\/a>.<\/p>\n <\/div>\n<\/div>\n First, Duo will require a second method of confirmation for a person logging in to view or edit sensitive data. Individuals will be asked to confirm their identity using a smartphone app, via text message to a device, via automated calls to a mobile or landline phone, or using a secured kiosk (for certain staff).<\/p>\n The login screen you’re used to seeing at\u00a0www.bu.edu\/buworkscentral\/<\/a>\u00a0will change slightly. Also due to the transition, Web Login-secured applications, including those linked from BUworks Central, will require you to log in again. These other applications do share the same login credentials as many applications at BU, so logging in more than twice during a session is very unlikely.<\/p>\n More and more applications to be compatible with the high-security login process so that you’ll be required to log in less often while using web applications.<\/p>\n <\/div>\n<\/div>\n If you’re unable to use the Duo Mobile App (e.g., due to device compatibility issues), you can use security token as an alternative.

<\/p>\n
\nI am studying abroad this semester and don't have an international phone plan, can I still use Duo?<\/h3>
\nYES! Duo works internationally, don\u2019t worry \u2013 Duo can work with or without cellular service or a wifi connection.
\nEven with cellular service disabled or without a wifi connection, you may use the Duo Mobile app to generate a\u00a0passcode\u00a0that you can use to authenticate. Simply choose the\u00a0Enter a Passcode\u00a0option when you get the Duo authentication prompt. To generate the passcode, open the Duo Mobile app on your phone or tablet and tap the button with the KEY symbol.

Yubikeys can be purchased from Amazon or directly from the Yubico.
