How can I change the email address associated with my Quickbooks account to one that I use more often? I tried to do this but got stuck when it asked for a password.

Hey there, ACC72. 

Thanks for stopping by this evening. There's two ways to change your email address that you use to sign in. From your Intuit account and directly within QuickBooks Online. Follow these steps below. 

From your Intuit account:

You can sign in to your Intuit account directly. In the Email address section, select Edit and change your email.

From your QuickBooks Online account:

1. Sign in to QuickBooks Online.
2. Select Settings ⚙ and then select Intuit account or Your account.
3. In the Email address section, select Edit and change your email. 

You mentioned that you've tried signing in but aren't able too. If neither of the above methods will work, you can get help recovering your account. Here's how you can recover your account. 

If you have any other questions or concerns, the Community is always open! Feel free to post at any time. Thank you and have a nice evening.
