Twilio is a developer platform for communications: the Twilio Customer Engagement Platform. Twilio’s programmable application program interfaces (APIs) are a set of building blocks developers can use to build the exact customer experiences they want.

Twilio can be used to send SMS with one-time password (OTP) codes to users logging into SonicWall appliances. For example, the SonicWall SMA 100 series and WiFi Cloud Manager offer the ability to communicate with SMS service providers like Twilio.
