Thanks for reaching out, @HOME2.

How's your day going so far? I hope all is well. 

To clarify, are you needing to change your QuickBooks Online account password? If so, you can follow the steps I'm including below to make your changes.

Please keep in mind your Intuit Account is connected to all of your Intuit products. Any changes you make apply to all of your Intuit products, including QuickBooks.

Here's how: 

1. Click on your Profile Icon in the top right corner of the screen in QuickBooks. 
2. Tap on Manage Your Intuit Account.
3. In the Intuit Account Manager, select Sign in & security.
4. Choose the User ID, Email address, Password, or Phone section.
5. Make your changes.
6. When you're done, hit Save.

That should do the trick. For more information about updating your password, check out Update or change your Intuit Account Sign-In Information. 

Please let me know if there is anything else I can assist you with. Take care and have a wonderful day ahead!
