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

Follow

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

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

@ecksmc so FIDO: what devices are en vogue? Titan/yubikey/nitro/?

@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

@ecksmc
I use Aegis and recommend it also.

For iOS users, I like RavioOTP.

@voltronic @ecksmc
FWIW Aegis is on Fdroid as well
Aegis Authenticator (Free, secure and open source 2FA app to manage tokens for your online services)

@ecksmc same reason they’d use Google docs/sheets instead of M365, I imagine - perceived cost savings. Gonna hafta read more on what happened though, since I don’t use Google Authenticator.

I do know from recently doing my annual refresh/clean install that if you have MFA enabled and log into your Google account from an unrecognized machine that it immediately alerts you on that account and any other you had listed in the security/recovery settings.

@Synical idk about the app

I use google prompt alert - Google prompts are notifications sent to your phone to confirm your identity you can then allow or deny the sign in from a new device
