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
