If you use Google 2fa authentication app you probably should turn OFF the sync to cloud option
Retool blames breach on Google Authenticator MFA cloud sync feature
Software company Retool says the accounts of 27 cloud customers were compromised following a targeted and multi-stage social engineering attack.
if anyone gets access to your google account they can then instal the google 2fa app that will enable them to then get all your 2fa codes and see what accounts you have then start hacking your other accounts
switching cloud sync off means they can't as the 2fa codes are only on your device
begs the question though
why is a company using google authenticator app in the first place for employees
sidenote: google should add the feature "verify device" then when a new device adds google authenticator app the device the app was 1st installed on gets an alert to verify or not
if you wanna ditch google authenticator app
try Aegis
open source app

sidenote:
you should enable google prompt
When you sign in to your Google Account via a new device you get a full screen alert notification on your main device(smartphone), you can tap that notification on your phone to confirm it's you or deny which will stop the sign in attempt - Google prompts give you info about the device, location, and time of the sign-in attempt.
enable it via your google account security 2fa
having google prompts enabled still allows you to to use 2fa app
@b4cks4w i don't use any of them
have read about them though YubiKey seems to be popular and would probably be the one i got/get if/when i switch
