Authy is a widely used (proprietary) two-factor authentication (2FA) application used on Android and Windows to setup 2FA for user-registered accounts on the internet.

All the user-provided 2FA tokens are stored on the cloud, which makes it easier for users to switch between devices without worrying about manual backup but also raises concerns about privacy issues and data leaks.

If you are currently using Authy on Android or Windows, you might not have any concern over it as you are already using it. To install it on your Linux system, you can follow the below steps for installation.
