Protect your business and your customers with API‑powered tools right for any use case or user. How Authy works PUSH AUTHENTICATIONS Elevate your security and enhance user experience with push authentications. Push authentications are more powerful than passwords. Instantly deliver a new, seamless experience for your user that adds context and confidence to their login. SOFT TOKENS Add versatility to your login experience with soft tokens. Soft tokens enable authentications anywhere. If a user can’t receive an SMS or push authentication on mobile or desktop because they’re offline or out of data, they can still login using time‑based one‑time password (TOTP). TOTP tokens are generated from a device specific shared secret. Allowing you to make risk decisions per device compared to device agnostic means of authentication such as SMS and Voice. SMS, VOICE, AND EMAIL SMS, Voice, and Email ensure every user can login securely. SMS, Voice, and Email are ubiquitous forms of both communication and authentication, allowing you to reach a massive audience without any onboarding barriers. SMS, Voice, and Email auth are a vast improvement from using a password alone, giving you both global reach and reliability. Meet the Authy API - the engine powering Authy. Authentication is the lock on the front door of your app. We’re the best locksmiths in town. Authy’s powerful API delivers you unparalleled security and a seamless user experience.
