OTP via SMS / voice
Global coverage for one-time 2FA passcodes. Authenticate users on any mobile device or landline, anywhere.
The Authy service is built on a world class communications platform, providing reliable SMS and voice delivery around the world. Multiple long and short codes in different countries and preregistered sender IDs are used to ensure timely delivery.
Our high-quality SMS platform automatically selects the right route across our network of aggregators and carriers. We use positive feedback to replace failing routes on the fly.
SMS is a capability found in all mobile phones, allowing for easy user enablement because it works without internet connectivity. Voice authentication allows for landline use and is the fallback for when users have no access to an SMS enabled device.
Delivered as a modern REST API, you can implement the Authy solution in a single sprint without worrying about availability, reliability or service security. We handle that for you. Just sign up and get started within minutes. Everything can be accessed immediately; we don’t hide our API behind a sales person.
"Identity is the new perimeter. Coupled with key security requirements, such as Twilio’s Authy, it can be secure, relevant, and delightful from an end user perspective."
We ensure the SMS only goes to a real handset and not to web portals, reducing the risk of compromised desktops in the authentication chain. (Note: only available in certain geographies.)
Authy allows you to choose a token length between 6, 7 or 8 numbers, making easy to find the right level of security for your application and increased usability where necessary.
Built in whitelisting and monitoring of numbers used for fraud helps prevent unnecessary costs and reduce fraudulent activity, saving you money.
We deliver the code or voice call in a range of languages, making it easier for the end user to understand the message they are getting. Language is automatically selected for the user based on their country code.
We can reach your users in over 200 countries and use multiple SMS carrier networks to give us the best confidence in the delivery of the codes.
To ensure full coverage of your users, you can offer either SMS or voice capabilities. This means even those in very remote locations with only a landline can still gain access to the token out of band.
Authy services applications with millions of users, for customers such as Twitch, Coinbase and SendGrid. We handle billions of API calls with a solution designed to scale as you do.
