I would like to sign in a new user

Hi paul158,

Welcome to the community family! QuickBooks offers you the flexibility to add new users as well as changing your credentials when needed. I want to make sure you have everything you need to complete your task.

The first article shared by @Fiat Lux - ASIA provides the step-by-step procedure to add, delete, or change user access. If you're interested in updating your current user info, here's how: Change your email, user ID, or password for QuickBooks Online, QuickBooks Online Accountant, and QuickBooks Self-Employed

I hope this helps! Feel free to stop by if you need anything else.
