Thanks for joining the thread, @kathyj7108.

I can share with you the details on how to fix it if QuickBooks won't accept the password. The first step is to make sure that you've got the update of QuickBooks to the latest release.

If this error appears after updating your QuickBooks, let's continue to check your email settings and filter preferences. It may be blocking your emails from QuickBooks unexpectedly.

Here are the steps to follow on how to review your email settings and preferences:

Gmail

1. Follow the steps to enable access for less secure apps.
2. You can also set access preferences for specific apps, like QuickBooks.
3. Go back into QuickBooks and email yourself a test transaction.

Else, proceed to turn off the 2-Step Verification feature for your Gmail account. It includes turning off for all apps.

Once done, proceed to the third step.

Yahoo! Mail

Yahoo! Mail uses a 2-Step Verification process. Review your security settings:

1. Go to your Yahoo Account Security page.
2. Turn on the Two-step verification and Allow apps that use less secure sign in features.
3. Go back into QuickBooks and email yourself a test transaction.

If you still can't send emails, use the Yahoo's generate third-party app passwords tool. It creates a random password you can use to connect QuickBooks. You only need to do this once.

1. Follow the steps to get a password.
2. Go back in to QuickBooks and email yourself a test transaction.
3. In the Password field box, enter the third-party app password. Then select OK.

When you're done, proceed to the third step through this article: Fix webmail password issues in QuickBooks Desktop.
