I want to ensure you’ll be able to login to your QuickBooks Online (QBO) account, @jp.ramasir.
Can you share with me the specific issue you’re having when logging into your master account? This way, I’ll be able to provide you with the right resolution. Additional information is appreciated.
Moreover, if you forgot your password and can’t log in, you can follow these steps to get around the issue:
From the sign-in page, select I forgot my user ID or Password.
Enter your phone number, email address, or user ID, and select Continue.
Follow the on-screen instructions to finish the process.
