We have lost a member of our company that was the quickbook admin...we do not know the log in ... how do we change admin user

Only the primary admin has the authority to transfer their role, Laura.

If possible, you can collaborate with the team member who left your company to have them assign their current role to another existing user in your QuickBooks Online (QBO).

Here's how:

1. Ensure they sign in to QBO as the current primary admin.
2. Select the Gear icon, then Manage users.
3. Look for the user to whom you want to transfer the role.
4. Make sure they're listed as Admin, as seen in the Role column. Otherwise, click Edit to change it.
5. In the Action dropdown, choose Make primary admin.
6. To confirm, pick Change primary admin.

If you're unable to reach the current primary admin, you can process a request to become the one instead.

Whenever necessary, consider updating your Intuit Account sign-in information to improve the security of your account.
