Overview

Authy provided two-factor authentication as a developer-friendly API and consumer app. Founded in 2011, the company let developers add SMS, voice, and TOTP-based 2FA to applications without building telecom infrastructure. Authy also offered a consumer app for managing 2FA tokens across services. Twilio acquired Authy in February 2015 for an undisclosed amount, integrating its 2FA capabilities into what became Twilio Verify — one of the most widely deployed authentication APIs on the web.

Why Authy is interesting

Authy made 2FA deployable at API scale before Twilio acquired it in 2015 — the technology still powers Twilio Verify for thousands of sites.

Product & use cases

Authy offered a 2FA API for developers (SMS, voice, push, TOTP) plus a consumer app for end-user token management. The API abstracted telecom and crypto operations so startups could add multi-factor auth in hours rather than months.

  • Adding SMS or TOTP two-factor auth to web and mobile applications via REST API
  • Enterprise 2FA deployment with centralized user management
  • Consumer token backup and sync across devices through the Authy app

Competitive landscape

Edge: Developer-first API design with both B2B infrastructure and a consumer app — rare dual-sided approach that gave Authy distribution among end users and engineering teams.

Authy competed in the early 2010s 2FA market by targeting developers first — API simplicity beat enterprise sales cycles for startups needing quick MFA. Duo focused on enterprise SSO integration; Google Authenticator was free but lacked backup and APIs. Twilio's acquisition gave Authy telecom scale and distribution through Verify.

  • Google Authenticator alternative

    Consumer TOTP app without API/backend; Authy offered cloud backup and developer APIs.

  • Duo Security direct

    Enterprise 2FA with Cisco acquisition; Authy was more developer-API focused pre-Twilio.

  • Okta adjacent

    Broader identity platform; Authy was point-solution 2FA rather than full IAM.

Notable stories

  • Twilio acquired Authy in 2015 primarily for its 2FA API — the deal expanded Twilio beyond voice/SMS into authentication infrastructure.
  • Authy differentiated from Google Authenticator by offering encrypted cloud backup of 2FA tokens, reducing lockout risk when users changed phones.
