Did anyone get ideas which is much better of these two? Or the difference between them? Google 2FA and Authy. I still didn't explore so much about Authy 2FA.
If you are a type of person who is privacy and security junkie then the important thing that needs to be considered when choosing a two factor authentication is that they are
open source and guarantees that the application is not a big spyware. Neither of these two application are open source.
But If I were to choose, that would be Authy. Based from my own experience, Google Authenticator is a hell of a lot to operate since it does not support multi-device hence, if the mobile phone has been lost, you will automatically have no access to your 2FA codes unless you have saved the backup codes (a must) given upon turning on your 2FA in your account. Fortunately, the good thing about Google Authenticator is that they added another feature to easily move your 2SV account across another device which is preferred to transfer to a separate mobile phone intended only for 2FA. But then, that's a
google product so it would be
Authy.
I am not sure about the difference but I saw mk4 commented with this post and I think he makes a point that storing private things yourself is better. It is not only about 2FA backups but generally also about synchronisation over devices. I don't want to sychronise everything I do over devices. If one of my devices is compromised, my data will be leaked. That's not good.
Why not use Authy? If having your 2FA backups stored on a company's servers is fine with you, then by all means go with Authy. But if you prefer storing your 2FA backups yourself, through an encrypted flashdrive and such, then try out Aegis.
Because Authy uses a third party server called
twilio to store your information in order to provide safety to your accounts which is their claim on their blog.
