Dear OneLogin Administrator,
After August 31, 2023, Twilio will block all U.S.-bound messages sent from unregistered 10DLC phone numbers.
Failure to contact Twillio and register your companies phone numbers may result in disruption to your MFA authentication.
If you are sending SMS messages to users in the US you must follow the instructions provided by Twilio to register an A2P 10DLC Campaign.
Regards,The OneLogin Team
