I would avoid Google Authenticator and Authy. GA does not have backups. Authy was bought by Twilio a while back and development stagnated. Both apps are closed-source.
I migrated from Authy to Aegis and it's much better, besides being open-source.
The biggest reason to not use Authy anymore may be that they were compromised in the same breach that recently hit LastPass:
