I wanted to remove an accountant but accidently removed my login to the company I do books for. How do I enable my login again? The owner can still log in and I am still an admin to his file.

Hi JAB50,

Welcome to Community!  It's essential that you have access to your QuickBooks Online account so you can complete your daily tasks in a timely fashion.  I'll be happy to help!

Based on the information you've provided, it sounds as though you've accidentally removed yourself as a user on the account.  In this situation, you can easily be given back user access by having the Primary Admin on the account, invite you back to the books.
