Not receiving verification text message to allow me to give access to my accountant?

Hi there, @paul-harbourmari. I'm here to ensure you'll receive a verification text message to give access to your accountant.

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 plan 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've entered was not selected as the default setting in QuickBooks Online (QBO) to send the text message verification. To fix this, you can setup 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.

Once everything is fine, manage your accountant access again. 

In case you no longer want an accountant to access your books, you can easily remove them. For the detailed steps, check out this link: Remove an accountant.
