Duo for International Travelers

The methods used to register devices or receive Duo prompts at MIT and nearby may not work successfully outside the US.

  • Duo authentication is associated with the phone number of your device. If you swap SIM cards during travel, you will not receive prompts.
  • Register multiple devices in case one is forgotten or stolen or broken. You can register multiple phone numbers and mobile devices and hardware tokens.
  • Anticipate mobile carrier timeouts and SMS Failures. Set up and use a Yubikey to avoid network issues.
  • Encode/enter international numbers correctly (must begin with plus sign followed by country code, e.g. +1 for US and Canada, +44 for United Kingdom).
