Objective 

The Authy multi-device feature allows you to set up multiple trusted devices to use the same Authy account. Multi-device lets users easily sync their account and 2FA tokens with a number of devices (like a mobile phone, tablet, etc.), or quickly add a new phone. This guide explains how the Multi-device feature works, and how to manually enable or disable it.

 

Product

Authy

 

Procedure

When you first create an Authy account, multi-device is enabled by default. This means you'll be free to set up another device to use your same Authy account and 2FA tokens*. All you'll need to do is download and install Authy on the desired device, add your phone number, and allow this new device on your original Authy installation.

Notice: For your tokens to sync to your multiple devices, Authy backups must be enabled.

In fact, we recommend all Authy users to take advantage of this feature, and install Authy on another device to use as a backup. Once you have a backup installation setup through multi-device, you'll be covered in case you lose access to one of the devices. Losing your phone or a broken tablet will no longer prevent you from accessing your secured online accounts. 

 

Automatic disable

Authy will automatically disable Multi-device when it detects that you have added an Authy app to more than one device. You will still be able to access your account from all existing installations, but you would need to manually enable multi-device to add another authy app to your account. Once re-enabled, Authy remembers this choice, and won't disable it again. We recommend users keep the multi-device feature to disabled when not wanting to add additional devices to their account as an extra security step.
