Password error when sending invoices

Hi, SN07. Let me guide you through some troubleshooting steps so you can send your invoices in no time.

First, if you haven't already, please update your QuickBooks Desktop (QBDT) to the latest version to ensure optimal system performance. 

Once done, I recommend checking your Yahoo Mail security settings, as Yahoo uses a 2-Step Verification process for added account protection.

Here's how:

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. Return to your QBDT and email yourself a test transaction.

In case you’re still unable to send emails, I suggest using Yahoo’s Generate Third-Party App Passwords tool. It generates a unique password for connecting QuickBooks to your Yahoo account. You'll only need to do this once, and it replaces your regular Yahoo password for QuickBooks integration.

Please note that if you’re batch-sending emails, the password will expire after sending 12 invoices or transactions. You’ll need to generate a new third-party app password to continue.

Here's how:

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

If the issue persists after following these steps, I recommend referring to this helpful resource for additional troubleshooting: Fix webmail password issues in QBDT.

I’ll ensure this conversation remains open for any future updates and discussions.
