About Twilio Verify
Twilio Verify is an API from Twilio for confirming that a person controls a phone number or email address. Developers use it to send one-time passcodes through channels including SMS, voice, email and WhatsApp, and to check the code the user enters, which supports sign-up verification and two-factor authentication.
Twilio Verify is a proprietary, vendor-hosted service with no self-hosted edition, billed on usage. Supported channels, fraud controls and rates are documented by Twilio on its site, and it suits developers who want to add verification quickly without building their own messaging and code-checking logic.
