Hello there, edna. It's our priority to help you log in to your QuickBooks successfully and get back on track.
We understand the importance of logging in to your QuickBooks account successfully. Allow me to share some details about it. In this case, you may need to ensure you're using the correct email and password. Once verified and still getting the same concern, you'll want to access your account on a private window. This helps our browser to work better and faster and to remove those cookies and caches that might block you from accessing your account. You can use these keyboard shortcuts to launch a new private window:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
If it works, you can return to your regular browser and clear your browser's cache. Then, you may see if it fixes the problem and gets started on the tasks at hand. However, if the incognito window is unable to work, you can use another supported browser.
