Hello there, @paperbirch.

I'll make sure you get the service you deserve and get back to business with QuickBooks Online (QBO), so you can manage your account and transactions accordingly.

Before we start, I'd like to verify if you've already tried performing the recommended troubleshooting steps (clearing cache and using supported browsers) and followed the fixes for common sign-in issues using QBO.

If you haven't performed the recommended fixes above, I encourage you to do so. If you've already executed them, but the log-in issue continues, I recommend contacting our Customer Care team. To do this, you can either utilize our test drive or start a chat with one of our support experts.

Once everything is all set, you may also want to check out one of our Help pages as your reference to guide you in managing your business growth and transactions in QBO: QuickBooks Learn and Support. It includes help articles, Community discussions with other users, and video tutorials, to name a few.

Keep me posted if you have other access and account management concerns in QBO. You can drop a comment below, and I'll gladly help. Take care, and I wish you continued success, @paperbirch.
