Why do I need to key in verfication code whenever I login to QBO

Hi there, @123146224871824.

Let me share some details about the verification process you're seeing in QuickBooks Online (QBO). 

If the Two-Step Authentication is enabled, QuickBooks will ask to verify your account upon every single log-in. This is to add another check to ensure it's you, adding extra protection if your password is stolen. If you'd like to disable this, you can do so using the steps below:

1. Sign in to your Intuit account.
2. Navigate to the Sign in & security tab. 
3. Select the 2-step verification section.
4. Turn the switch button off.
   
5. Enter your password and click Continue.

Once this feature is disabled, you'll only be asked to verify your account when you log in from a new device or browser and when you clear your browser's cached data. 

Additionally, if you need to make changes to your account, these articles will surely be useful:

• Update Your Intuit User Account
• Change Your Email, User ID, or Password

You can always reach me here if you have further security concerns. I'd be happy to help. Thanks for coming to the Community, @123146224871824!
