Strong Authentication
Passwords no longer provide sufficient security for user login and authorization of high-value transactions. Two-factor authentication verifies your user's identity while protecting your app or website from data loss, fraud, and malicious intent. Authy two-factor authentication adds strong security with first class app support via soft tokens and push authentication while supporting legacy voice and SMS channels.

Microsoft Authenticator is partnering with Twilio Account Security to bring industry-best two-factor authentication to protect customers of Microsoft.
