Once verified, you will be sent a 9-digit code via text message that can be used in place of "push" or the generated code from a BoilerKey token or the app.

You will be asked to verify your identity by providing your career account login, 10-digit PUID number and your date of birth. Once you have registered your cellphone number, go to any page requiring BoilerKey to sign in and click “Issues with your BoilerKey?” This will start the BoilerKey self-recovery process. This option is for the Duo Mobile app users who replaced a smartphone or for those with a hardware token who either left it at home or lost it.

*You must have first registered your cell phone number by visiting the Update Cell Phone tool ( ). So that you can still access your account, there are two steps you can take now, BEFORE you lose your BoilerKey or leave it at home. Please contact your campus unit’s IT support group or the ITaP Customer Service Center at 76. If the BoilerKey is lost or if you suspect that it has been stolen or used by a third party, you should immediately report it.
