🚨🚨🚨

This library is no longer actively maintained. The Authy API has been replaced with the Twilio Verify API. Twilio will support the Authy API through November 1, 2022 for SMS/Voice. After this date, we’ll start to deprecate the service for SMS/Voice. Any requests sent to the API after May 1, 2023, will automatically receive an error. Push and TOTP will continue to be supported through July 2023.

• Twilio Java helper library
• Verify API reference

Java Client for Twilio Authy Two-Factor Authentication (2FA) API

Documentation for Java usage of the Authy API lives in the official Twilio documentation.

The Authy API supports multiple channels of 2FA:

• One-time passwords via SMS and voice.
• Soft token (TOTP via the Authy App)
• Push authentication via the Authy App

If you only need SMS and Voice support for one-time passwords, we recommend using the Twilio Verify API instead.

More on how to choose between Authy and Verify here.

Authy Quickstart

For a full tutorial, check out either of the Java Authy Quickstarts in our docs:

• Java/Spring Authy Quickstart
• Java/Servlets Authy Quickstart

Authy Java Installation

Dependencies

This project uses json.org, you can find the json.org jar versions here

• Ant: no need to include json.org since ant already includes it in the final jar.
• Maven: need to include the json.org jar in your jar external libraries.

Usage

Add the library to the project by putting it in the dependencies section of your pom.xml:

<!-- https://mvnrepository.com/artifact/com.authy/authy-java -->
<dependency>
    <groupId>com.authy</groupId>
    <artifactId>authy-java</artifactId>
    <version>1.5.0</version>
</dependency>

To use the Authy client, import the API and initialize it with your production API Key found in the Twilio Console:

import com.authy.*;
import com.authy.api.*;

AuthyApiClient client = new AuthyApiClient("your-api-key")

2FA Workflow

1. Create a user
2. Send a one-time password
3. Verify a one-time password

OR

1. Create a user
2. Send a push authentication
3. Check a push authentication status

Phone Verification

Phone verification now lives in the Twilio API and has Java support through the official Twilio helper libraries.

Legacy (V1) documentation here. Verify V1 is not recommended for new development. Please consider using Verify V2.
