Can I disable 2-Step Verification once it has been enabled?
No. There is no option to disable it.
Please note that OIT cannot disable 2-Step Verification on any account. If users cannot access the account, they must follow the 2-Step Lockout procedure to gain access to the account.
What do I do if I receive a message that I am locked out of Duo Security?
Your account will lock after too many failed attempts to authenticate. The lock-out will automatically be removed after a period of time.
What if I am unable to generate a code and I am locked out?
Users with 2-Step verification should always have a backup mode configured. All users must print a list of one-time-use verification codes during the enrollment process, as outlined in the video above.
If you do not have access to your backup verification codes, you should contact the OIT Support center during regular operating hours (Monday 鈥� Thursday, 7:30 a.m. 鈥� 10 p.m. EST, Friday, 7:30am to 5:00 pm and Saturday, 8 a.m. - 4:30 p.m. EST).

You will also be asked a series of authentication questions.
Does the 2 Step Verification application use my data plan?
The Duo Mobile application uses a very small amount of data to send push notifications. If you received 500 push notifications per month, that would equate to 1 MB of data usage. Less than loading one web page to your mobile device. You may disable push notifications if you do not want to use any data; however, you will have to manually enter a code from the app as a passcode to log in. Data fees may be incurred during the installation of the application and during any updates if auto-update is enabled. We recommend connecting your device to the College wifi system when on campus.
What if I have no cellular or/ WiFi connection?
The Duo Mobile app can generate passcodes with no Internet or data to generate codes. We recommend connecting your device to the College wifi system when on campus to ensure the best user experience.
I have a new phone, and I am enrolled in 2-Step verification. What do I do?
If you are migrating between Apple and Android, you should log in prior to disposing of your old phone and add your new device. If migrating between similar devices and you have cloud backups enabled, you can use Instant Restore. Please see the videos below:

Why am I getting an 'Access Denied' error message?
There are two reasons you could be getting this message. To better secure your accounts, users may not connect from TOR endpoints or networks used to anonymize or proxy traffic. In many cases, using a VPN to obscure your location will cause an 'Access Denied' message. Disable your VPN and try again.
