You got a new phone and installed Duo app, but now it doesn't want to register your new phone or send out a Duo push. Same phone number, but the phone hardware is new. Why do I do to remedy this? You have two options: 1. During normal business hours, Monday - Friday, 8:30am to 4:30pm, you need to contact University IT Helpdesk at 408-554-5700 to seek assistance on resetting your Duo app account. Once this is done, you can then re-register your new phone. OR 2. If it is after-hours or on the weekends, and you cannot get a hold of University IT Helpdesk, but you need to get into a Duo security protected app, like SCU email or Workday; then you need to go to www.scu.edu/technology/get-connected/security-tools/ and generate your one time passcode when prompted by Duo. Once you have time to contact the IT helpdesk, then you can reset your Duo app account and re-register your new smart phone.
