Hello there, @pbentvelsen-onpu. I'm here to help you get through this so you can successfully set up a two-step verification in your QuickBooks Online (QBO) account.

First, allow me to share some possible reasons why you didn't receive a verification text message:

• The phone number that is associated with your Intuit Account is incorrect.
• Your phone plan doesn’t include SMS text messages.
• Your phone plan doesn’t allow you to receive messages from shortcodes. You'll want to reach out to your phone provider to see if your project can be configured to receive SMS messages and shortcodes, allowing you to receive Intuit validation codes.

It's also possible that the phone number you entered was not selected as the default setting in QuickBooks Online (QBO) to send the text message verification. To fix this, you can set up code verification via text message. Here's how:

1. Log in to your Intuit account.
2. Then, from the left menu, click Sign In & Security.
3. In the Two-step verification field, select Turn on.
4. Ensure your phone number is correct, and select Text message to receive a standard six-digit verification text code.
5. Click Turn on.
6. Enter the code, then select Continue.

Then, go back to the QBO login page to sign in and access your account.

Please let me know in the comments if you have other multi-factor authentication concerns in QBO. I'm always ready to help. Take care and have a great day.
