Hello there, mareti_cpsi.

Thanks for taking the time to reached out to us. I'm here to help and provide some insights on how to reset user's password. 

Master admin doesn't have an option to reset the user's password for security purposes. Since this issue requires the gathering of personal information, I encourage your user to call our QuickBooks Online Support Team. They have additional tools to reset the user's password. 

Here's how to contact our phone support: Get help with QuickBooks Online.

I also attached some articles for future reference: 

• How to add or remove an accountant user?.
• How to reset your password or recover your user ID?.
• How to change your user ID or password?.

Don't hesitate to leave a comment below if you have additional questions about User's information. I'm always help to help you out.
