Some online services and web applications let you protect your account with a mobile-generated passcode. Use Duo Mobile to generate these passcodes, and keep all your accounts in one app.
How to Set It Up
- Install Duo Mobile for iPhone or Android.
- Follow the instructions to turn on two-factor authentication (sometimes called two-step verification) for your account. Ignore any mentions of Google Authenticator or other mobile applications — you'll be using Duo Mobile instead.
- At some point you'll be shown a barcode to scan. Open Duo Mobile and tap the "+" icon or the "Add Account" button to add a new account. Use Duo Mobile to scan the application's barcode:
Scan the barcode on the screen:
Most services also offer a secret key that you can enter if you can't scan the barcode. Tap the "No Barcode?" button and select an account type from the list. Use the "Account" field to name the account (e.g. "Dropbox", "email@example.com", etc.). Type the application's secret key into the "Key" field on your phone.
Finally, tap the key next to the account name to generate a passcode. Type the passcode into the box on your computer to verify that the passcode generator is working properly. Then click "Next".
You're done! Now you'll use the Duo Mobile app to generate a new passcode if you're asked for one when you log into your account.
Please note: because we use the most secure storage methods on your device, if you wipe data from your device, or upgrade your device, you will need to reprovision your accounts. Please be sure to follow the recommended backup directions for your third-party accounts, e.g., a phone number or backup code.
