2-Step: Obtaining a One Time Passcode for Office 365
Office 365 does not prompt for 2-Step unless it detects there is something abnormal regarding your login and has assigned a risk level. If you have lost or forgotten your 2-Step device, you can generate a one-time passcode that can be used to complete 2-Step. This one-time passcode is good for one use and must be used within 60 minutes of issuance. In order to generate a one-time passcode, you will need to sign in and provide the answers to your security questions. If you have lost your 2-Step device, please contact the Technology Helpdesk immediately.
