Hi there, accounts. I've got the information needed to set up a password for your client's account.
You don't have to worry about creating your client's password for their account since they'll be the ones who'll set it up. When you invite your clients to your accountant subscription bundle and subscribe to QuickBooks Online (QBO) for them, they'll receive an email where they can set up their user info and password for their company.
Once finished, they can use the same credentials to log in to their account.
