Authy Error: "Multi-device is disabled"

"Multi-device is disabled. to enable open Authy on your other device and go to Settings -> Devices"

This message will appear if you have installed Authy on another device and disabled "Allow Multi-Device".

The best practice would be to install Authy on at least two devices and then disable “Allow Multi-Device” after that.

If you are unable to access the other device where Authy is installed, please contact Authy support for additional help:
