GENERAL

What is Multi-Factor Authentication (MFA)? Multi-Factor Authentication (MFA) is a method of system access control in which a user is only granted authorization after successfully providing a second authentication method beyond the basic username/password. MFA combines knowledge (something you know) with possession (something you have). At UCSC, MFA will combine CruzID and Gold password with cell phone, landline phone, tablet, hardware token or one time use passcode. Duo Security is the vendor facilitating the ‘possession’ half of MFA at UCSC.

Why do I need this?  Passwords are becoming increasingly easy to compromise. They can be stolen, “phished”, guessed, and hacked. New technology and hacking techniques combined with the limited pool of passwords most people use for multiple accounts increases vulnerability. UCSC is also scheduled to begin using the new UCPath system in late 2019. In order to access the UCPath system, it requires Multi-Factor Authentication (MFA). In order to avoid conflict with the launch of the UCPath project, all users must be enrolled in MFA by the deadline in October 2019.

What devices are supported? UCSC supports a range of electronic devices including:

  • iOS smartphones and tablets
  • Android smartphones and tablets
  • Blackberry devices
  • Windows phones
  • Basic cell phones with and without text message capabilities
  • Landlines (Desk Phones)
  • Hardware tokens

It is strongly recommended that you add an additional device to your MFA account to serve as a backup. This additional device could be a desk/landline, tablet or trusted family/friend phone number. Please follow the Add a New Device instructions. Be sure to Manage Devices and set up the correct phone number as your default. If you are a DC-VPN user and want to receive a phone call to your backup (not default) device enter ‘phone2’ (or push2, sms2) into the Second Password field.

How often do I need to use MFA? As of now, most online services are set to timeout after 12 hours. However,  some appliations contain sensitive data and will require an additional MFA authentication. Also, some of these applications may time out sooner than 12 hrs.

back to top

What is a passcode? How does it differ from a password A passcode is a one-time use number utilized for MFA (provided by Duo) via Duo Mobile App - Passcode option, text message or token. For most online applications and after authenticating first with your CruzID and gold password, the passcode will be entered into the 2nd login window, under the `Enter a Passcode` field. DC-VPN users will enter the passcode into the Cisco AnyConnect ‘Second Password’ field. For Cisco AnyConnect DC VPN, the password field refers to your UCSC Gold password which is reused for all logins.

I recently graduated, and did not sign up for MFA. Do I still have to? No. As soon as the Registrar's Office categorizes you as a prior student instead of active, you will no longer be prompted to MFA.

back to top

I missed my requirement deadline. What do I do? Have your authentication device (such as your phone) ready. If you do not have an authentication device, contact the ITS Support Center ( help@ucsc.edu or 831-459-4357) for assistance. Log into any application that requires you to use your Gold password. Follow the instructions for setting up and enrolling a device  on our device enrollment page. . You need to successfully set up your verification device before you can enter the application. If you can only use a hardware token, contact the ITS Support Center. After you have set up your device, you can now start using it to authenticate. For instructions on how to authenticate into CruzID Gold systems, please view our authenticate with MFA page..

DEVICE SELECTION

What methods can I use to authenticate? Based on preferences and device availability, there are several convenient authentication methods. Users must first enroll their desired devices in CruzID Manager.

  • Push Notification: via Duo Mobile App: If the Duo Mobile App is installed on a smartphone or tablet, a push notification is received to either approve or deny the authentication attempt. No manual entry of a passcode is required at login.  * This is the most popular method using only a single button to MFA (vs. typing a passcode per login).
  • Text Message (SMS): A batch of one-time use passcodes is sent via text message. An unused passcode is then entered into the ‘Second Password’ field of Cisco AnyConnect.
  • Phone Call: A telephone call to any cell phone or landline will prompt approval or denial of the authentication attempt.
  • Passcodes: via Duo Mobile App: If the Duo Mobile App is installed on a smartphone or tablet, a single passcode is retrieved by tapping the key image next to "University of California Santa Cruz" in the mobile app. This passcode is entered into the ‘Enter a Passcode’ field on the Duo Authentication page.
  • Hardware Token: a small lightweight keyfob that can be attached to your keychain. Pressing the button on the keyfob will generate a passcode for you to use with MFA.  Tokens can be obtained by contacting the  ITS Support Center .

How many devices can I set up? Can I choose them all for multiple backup options?  You can set up an unlimited amount of devices. We encourage you to set up as many as you need.

back to top

There are so many authentication methods, how do I know which one to choose? Most users with smartphones prefer to use the Duo Mobile Push Notification authentication method as it requires a single touchpoint rather than retyping a passcode to login. There are several other options including text messages (SMS), phone calls, and more. Review the Device Overview and Authentication Quick Guide to determine which authentication method works best for you. Remember, you can always change your preferred authentication method after enrollment by logging into CruzID Manager to Manage Devices or elect to use different phone numbers (FAQ: Can I use multiple devices with MFA?).

How do I find/download the free Duo Mobile App? Select appropriate link ( iOS, Android, Windows, Blackberry) or search for “Duo Mobile” in your smartphone’s application store and then install it using standard app installation instructions. App size varies by platform (iOS 7.4MB, Android 9.9MB, Windows 4.22MB, Blackberry 115KB)

back to top

I don't want to install the Duo Mobile App! Can I enroll my smartphone without doing this?  Yes you can. Instead of following the instructions for enrolling a smartphone, follow the directions for enrolling a basic cell phone.  This will allow you to receive passcodes on your smartphone via SMS and as well as allow you to authenticate via a phone call. 

If you ever decide to start using Duo Mobile, follow the instructions on how to add a new device: smartphone. The instructions will be similar, and you will be asked to overwrite the existing phone number in CruzID Manager. 

back to top

Can I MFA without a data and/or text plan for my device? The Passcode via Duo Mobile App option works without a data plan, text plan, or even a connection. The app can generate the required code without the need of either a telephone signal or data plan, and it can do so anywhere in the world.

back to top

Do I need a smartphone? No. Duo provides a great deal of flexibility and you do not need a smartphone to use it. Duo can send a text message to a regular cell phone or place a phone call to your basic cell phone or landline phone.

back to top

How do text message passcodes (SMS) work? SMS passcodes are sent via text message. With the proper prompt, a text message is sent containing 10 one time use passcodes. A user can only have 10 valid passcodes at a time. Each new batch of 10 passcodes voids any remaining passcodes from the prior batch

back to top

I don't have a cell phone? If you don’t have a cell phone, you can use a tablet, your landline phone or hardware token to MFA. When using a landline, you will receive an automated phone call that requires you to hit 1 to confirm your identity. The hardware token will generate a passcode that you enter into the ‘Enter a Passcode’ field on the Duo Authentication page.

back to top

I am travelling internationally. Will I be able to receive a phone call/text message? Phone calls and text messages are also sent to select non-US phone numbers. Our current plan with Duo Security allows each user to utilize up to 20 telephony credits per phone call and/or text message. For more information please view the telephony rate card on Duo Security's site. To avoid high roaming charges when out of the country, you can utilize the Duo Mobile App - Passcode functionality, as it does not rely on cellular service to generate passcodes. If that is not an option, a batch of 10 passcodes via text message (SMS) can be sent ahead of your travels. You can also use a hardware token to generate passcodes. For more information on how to be prepared when traveling, please review our International Travel webpage.

back to top

How do I change/remove/add a new device? Please follow the Add a New Device or Manage Devices Instructions.

back to top

What precautions should I take when using MFA at a shared computer such as at the library? Shared  computers, like those in labs, public libraries, shared workstations in offices, or a computer borrowed from a friend, should always follow secure practices for SSO. Please see our (SSO) Single Sign-On page for more details.

 

back to top

I already use DUO for an application, will I need to re-enroll? If you use Duo for a UC Santa Cruz application (like DC-VPN) then you will not need to enroll. If you use Duo for anything else (non-UCSC application, i.e. ,UCOP ) then you do need to re-enroll. But you will use the same Duo app that is already on your phone - no need to reinstall it.

back to top

If I authenticate using my personal phone (smart or cell), will I be charged?  Charges depend on your carrier and plan but are very nominal. The Push notification is 2kb. The SMS text is standard text pricing. The phone call is the cost of a standard call. To avoid charges you can use the Duo Mobile app passcodes or the Duo token.

I’m trying to use the Call Me (phone call) method to authenticate but can’t seem to do so, even though I followed the prompt.   Some phones on campus are not upgraded to  digital/VOIP. For these phones. tones must be enabled in order to accept/approve the phone call authentication. This is done by first selecting '9'. You do not need to wait for the message to complete to select '1' (or '9' + '1' if you need to enable tones).

back to top

My hardware token stopped working. A hardware token is a physical device that generates a numeric passcode. These tokens can occasionally get out of sync if too many unused passcodes are generated. You can attempt to resync on your own by trying to authenticate three times, entering a valid passcode from your token each time into the 'Enter a Passcode' field. For more information, please view the Duo site's page on hardware token re-synchronization . If your hardware token does not resync after the 4th attempt, Contact the ITS Support Center (help@ucsc.edu or 831-459-4357 option 1) if your token stops working or if you can't log in with the passcodes it generates.

Sometimes the  Duo authenticate window (iFrame) does not show up.  Try these steps:

  1. Try to authenticate in an Incognito window (or equivalent). Does it go away? If not, go to step 2.
  2. Enable/disable your browser plug-ins until you find the culprit 
  3. Let us know so that we can add it to our list of known culprits. Call, 831-459-HELP (9-4357)  or submit a ticket to the Support Center.  Users who are more likely to get this are users who use various browser extensions or complex browser setups that may in some way alter the normal load of the page.

How do I manage cookies for my browser? How do they affect Single Sign-On (SSO)?

Depending on how your browser is setup, some settings can interfere with SSO. This can cause issues with how often, or how rarely you get asked to authenticate with your device.

Your browser may try to hold onto your current browsing session. When your browser holds on to your session, you’ll stay logged in longer and won’t get prompted to MFA when you close and reopen your browser.

If you are working with sensitive data and would prefer to keep your browser from holding on to your session, please follow the following steps.

Prevent Chrome from holding on to a session:

  1. Open chrome, then go to Preferences.
  2. Scroll down to the On Startup Section. Then make sure that Continue where you left off is unchecked.

Prevent Firefox from holding on to a session:

  1. Open Firefox, then click on the menu button in the upper right corner, then click preferences.
  2. Under the General seI am getting an Invalid Certificate (iPhone) / No Internet Connection (Android) error when I try to MFA on my phone.ction under startup, make sure that restore previous session is unchecked.

 DC-VPN Users

How does MFA work for DC VPN? Cisco AnyConnect displays three fields for DC VPN users. When you attempt to access DC VPN the Username/Password fields remain unchanged. The third field ‘Second Password’ requires users enter in ‘push’, ‘sms’, ‘phone’, and/or a valid passcode. Please refer to the Quick Guide for specific connection instructions.

back to top

Authentication instructions for Cisco AnyConnect DC-VPN. Please follow the instructions for the selected authentication method (Duo Mobile App - Push Notification, Duo Mobile App - Passcodes, Text Message (SMS), Phone Call, Hardware Token)

I’m already enrolled in MFA for DC-VPN. When it’s time for my group to enroll in DUO, do I have to re-enroll? No. We will do a one time manual sync for all enrolled/existing users in DUO and populate our grouper group as needed.

back to top

I use DC VPN occasionally, but do not see the MFA link under Advanced in CruzID Manager. If you don’t see the MFA option in CruzID manager, Contact the Support Center in Kerr Hall Rm54 (help@ucsc.edu or 831-459-4357 option 1).

back to top

I’m locked out of Duo | MFA | DC VPN, what should I do? After several failed login attempts, users will be locked out for 30 minutes. If after 30 minutes, you are unable to authenticate via all your configured devices contact the Support Center (help@ucsc.edu or 831-459-4357). If you are having trouble receiving a push notification, please verify you have cell service or use an alternate authentication method.

back to top

When I enter in ‘push’ into the DC VPN ‘Second Password’ field nothing happens? There are a few reasons you might be having this problem. First make sure that you have your smartphone enrolled properly as your default device by following the Manage Devices instructions. After that verify that notifications are allowed ‘turned on’ for the Duo Mobile App. If you are still unable to receive push notifications, contact the Support Center (help@ucsc.edu or 831-459-4357 option 1).

back to top

How often do I need to use MFA? If you are using DC-VPN, MFA will be required each time a new connection to DC VPN is created. DC VPN session timeout is set to 12 hours. All DC VPN users are required to use MFA.

back to top

What VPN clients are supported by MFA? The Cisco AnyConnect client is the only supported DC VPN client.

back to top

I’m trying to use a phone call to authenticate but keep getting a timeout message from Cisco AnyConnect. Tones must be enabled in order to accept/approve the phone call authentication. This is typically done by selecting '9' from campus phones. You do not need to wait for the message to complete to select '1' (or '9' + '1' if you need to enable tones). If you still receive a timeout message from Cisco AnyConnect, try uninstalling/reinstalling the Cisco AnyConnect client. Windows users can do this by going to 'Start > Programs > Cisco Systems VPN Client > Uninstall VPN Client' and Mac users can go to 'Applications > Cisco > Uninstall AnyConnect'. Then follow VPN Client Installation instructions. If you need help doing this, please contact the Support Center (help@ucsc.edu or 831-459-4357).
