Hi Sal Singapore!

Good to see you again. Let me show you how to properly configure QuickBooks Online and Google Authenticator.

First, sign in to accounts.intuit.com and proceed to the Sign in & security section. Based on your screenshot, your Two-step verification is turned off so we have to turn it on. Select either Text message or Voice call, tap Turn On and enter your password.

Once done, it should look like this:

Click the green ON button and you'll be routed to the Two-step verification window again. This time, there'll be a Turn on Authenticator app button.

Click it, choose your type of phone, tap Continue, and you'll see the QR Code that you need to scan using the Google Authenticator app or manually enter the setup key.

Then, the app will give you a six-digit code labeled "Intuit" that you need to enter in the box provided. Note that you'll need to use the most updated code since the app refreshes every 30 seconds. Once everything is good, click Verify and save.

If you successfully linked the Google Authenticator, this is how it looks like:

Still can't find the Turn on Authenticator app button? Please perform these steps:

• Use an incognito window and turn it on from there.
  • Google Chrome: Ctrl + Shift + N
  • Safari 11 or newer: ⌘ + Shift + N
  • Mozilla Firefox: Ctrl + Shift + P
  • Microsoft Edge: Ctrl + Shift + P
• Clear the cache to fix the browser-related errors.
• Use an up-to-date browser.

I'm hoping you'll be able to set it up this time. I'll be here if you need anything else.
