Needing to change my username / log in email for my QuickBooks accounts. As my old one will become obsolete. How do I do this?

Changing the email address you use to sign in is my top priority, info1645. 

I have here the easy steps on how to change your credentials in QuickBooks Online (QBO). This way, you can use an updated credential on your account. 

Here's how:

2. Choose the Sign-in & Security button on the left pane. 
3. Edit the User ID and Email address field.
