As part of our continued efforts to improve account security, the Office of Technology will be disabling support for older Duo Mobile passcode methods on June 1. Specifically, the older HOTP (HMAC-based One-Time Password) passcode method—still available on Duo Mobile versions 4.48 and earlier—is less secure and more vulnerable to malicious activity. These versions will no longer be supported after June 1.
What You Need to Do. If you’re using Duo Mobile version 4.48 or earlier, please update to the latest version before June 1 to avoid disruptions to your Seminary account login. The current version is 4.87.
How to Check Your Version:
- Open the Duo Mobile app.
- Tap the menu icon (☰) in the top-left corner.
- Your current app version is listed at the bottom of the sidebar.
Already on version 4.49 or newer? You’re all set! Push notifications and TOTP (Time-based One-Time Password) passcodes will continue working as expected. If you have any questions or need help updating your app, please contact the Help Desk at helpdesk@luthersem.edu.
