Absolutely, on the condition that you encrypt the device where you have installed gogle auth.
The reason people use authy and the like is because they make it simple to recover if you lose access to your device (lost, stolen, broken). My work around this is to take a screen cap of the QR codes and encrypt them with gpg. You could also save them inside a password manager (especially for less technical people).
