You can use the Duo mobile app (available for smartphone or tablet) to generate passcodes even if you don't have an Internet, Wi-Fi, or a cellular connection.
The most common reason for your account to be locked out is from multiple incorrect
NetID password attempts or multiple failed Duo login attempts in a row. Wait for your
NetID and your Duo access to both automatically unlock after 10 minutes, or contact
the OTS Faculty/Staff Help Center at 410-704-5151 for assistance.
When authenticating with Duo through a web browser, you may see a "Remember me for
30 days" option. If the computer is not a shared or public machine, you can enable
this option to avoid Duo authentication requests for up to 30 days. This will remain
in effect as long as you are authenticating on the same computer/browser, and do not
clear browser cookies. If you configured Duo to automatically call your phone or send
you a push notification, the "Remember me for 30 days" option may be grayed out or
hidden when the Duo prompt first appears. If the option is unavailable, you must click
"Cancel" on the blue bar, and repeat the authentication process to access the “Remember
me” checkbox.
You do not need to have a mobile device to use Duo. Landlines (like an office or home
phone) can be used to authenticate via a phone call. In limited circumstances, a hardware
token (a small electronic device that may be attached to a keychain and generates
a passcode) can be requested by contacting the OTS Faculty/Staff Help Center.
Yes, the Duo mobile app is free. However, the Apple App Store requires payment information
on record even when downloading a free app.
