Hi there, @Eddie13.

Logging in to your QuickBooks Online seamlessly is my top priority, so you're able to get back to your business.

Have you tried the workaround steps above provided by my colleague katherinejoyceO on this thread? If the issue persists after following the troubleshooting steps, please reset your password as an alternative option. 

Here's how: 

1. Go to the QuickBooks Online sign-in page.
2. Click I forgot my user ID or Password on the bottom part. 

       3. Enter the code that is sent to your phone number or email address. 

       4. Follow the onscreen instructions.

For more details, check out this article: Reset your password or recover your user ID for QuickBooks Online.

If the issue keeps going, I'd recommend contacting our Payroll Support Team using our sample account. They have tools capable of pulling up your account in a secure environment and send a ticket to our engineers for review.

You may refer to the steps outlined by SashaMC in this thread. Ensure to call them within business hours to quickly address your concern. 

I've added an awesome article that might help you handle your credentials, business information, data, and security: Account Management.

Notify me if the comment section how the call goes or if you have other questions about logging in. I'm willing to assist you further. Keep safe always.
