How can I view WHO has signed onto the QB system?

QuickBooks Online (QBO) offers an Audit Log feature to view user's activity, kpm006.

We can use the Audit Log to know who uses the account and for the logged-in and logged-out time. Let me show you how.

1. Go to the Gear icon and select Audit Log.
2. Click All Users in the drop-down arrow.
3. Select the Date and the Events.

For more details, check this link: Use the audit log.

Additionally, see this article about adding users to help with company operations and bookkeeping: Add and manage users.

As always, feel free to visit our QuickBooks Community help website if you need tips and related articles in the future.

Feel free to return to this post for more questions about user login. It's my pleasure to help you again.
