Can i add a 2nd user...give them their own login ID and password

Hi, Matthew-C-Grays.
Glad to have you in the QuickBooks Community. I can help with adding another user. Adding multiple users can help your business run more smoothly, so you don’t have to everything alone. This article will show you what you need to know to add a user, delete a user, or edit a user’s access. Manage Users for QuickBooks Online. I hope this will help. If there's anything else I can provide to assist let me know by simply replying below.
