To use a good 2Fa service you don't need Google Authenticathor or any other Google service.
There is a better application called Authy. I wrote about it some time ago.
Also, i don`t think decentrralization is useful here. Bitcoin should be centralized but a 2FA software doesn't need to be decentralized...
But one thing that many people do not know is the fact that Google Authenticator (GA) does not save your 2FA accounts in your google account. So if you lose your phone you lose access to all accounts linked to your GA (unless the site has some additional recovery mechanism).
So if you use GA it is worth taking at least one of these two precautions:
-You should always note the key when registering an 2FA account. Few people realize, but there is always a sequence of numbers below the QR code (or somewhere else on the website) when you register that account on your GA.
- Register the account on another device, such as a tablet.
An excellent alternative to GA is Authy app. This program works just like GA, but it saves your access accounts. That way, if you lose your cell phone, that's okay, as your data is backed up in the cloud.
Authy has an option to prohibit the registration of new devices. So if someone steals your Auth password, they can not add an additional device, unless if an authorized device allows the registration of new devices to your account.

Edit 2:
You can also try Yubico, a USD stick authentication device. It is a more secure and better solution, however it has a cost (20-60 usd)

Are they using centralized servers or not?
If the answer is YES, then I think we do need them.
btw did you mean Bitcoin should be DEcentralized
or centralized like you wrote ?PS
I tried Authy.
For desktop I am using WinAuth at the moment
