Tech tip: Create backup codes for MFA-Duo

Sooner or later, you just might find yourself in a jam, unable to find your phone. Or perhaps you might find yourself in a situation where you can’t use your multi-factor authentication-registered device, like in a no-phone-allowed classroom or a secured location. That’s why it’s always a good idea to generate a list of MFA-Duo backup passcodes for future use. This detailed KnowledgeBase (KB) article walks you through the simple steps: 4 steps to generate backup passcodes Important note: Backup passcodes should be stored offline in a secure place, and they expire after 4 months.
