Authy – code generator for two-factor authentication

Authy: Advantages and Disadvantages

Authy is a two-factor authentication (2FA) application available for iOS and Android mobile operating systems. This application provides security for online accounts by generating temporary passwords, syncing data across devices, and securing information with a master password and encryption. Authy supports various online services and provides notifications about events in your accounts.

We can note the following advantages of the Authy application:

• Device synchronization. Authy allows you to synchronize your data across different devices, so you can access your OTPs on other devices if you suddenly leave your phone at home or it runs out of battery.
• Support for various online services. Authy supports many popular online services and web applications, allowing you to use it to add two-factor authentication to most of your accounts.

Authy also has some disadvantages:

• Dependence on an internet connection. To use the Authy app, you need access to the Internet. This means that if you don't have a network connection, you won't be able to access your data or generate one-time passwords.
• Limited access to third-party devices. If you don't have access to your device on which Authy is installed and you haven't synchronized it with other devices, you won't be able to access your OTPs or manage your two-factor authentication.

How Authy Works

The Authy app is quite simple to set up and is available for Android and iOS mobile operating systems. The principle of Authy's operation is based on creating a secure mechanism for generating and storing one-time passwords, providing convenience for users and an additional level of protection for their online accounts.

• Installation on a mobile phone. The user installs the Authy app on their mobile phone. Then, they link the app with the corresponding online service or application that requires two-factor authentication.
• Generating OTP. After linking the app with an online service account, Authy begins generating one-time passwords (OTP) based on a secret key, which is stored in encrypted form on the user's device.
• Using OTP. When attempting to log in to a user account on an online service requiring two-factor authentication, the user enters their primary password, and then an OTP is requested. Instead of receiving an OTP via SMS or a special device, the user can get it directly through the Authy app.
• Confirming login. After entering the OTP from Authy into the corresponding field on the online service, the user confirms their identity. The online service compares the provided OTP with the expected value, and if they match, the user gains access to their account.
