Hi there,
Welcome to the Community. It's important you're able to to access your account while traveling. Rest assured, I'll be happy to assist you so you're on the right path.
QuickBooks provides the flexibility that allows you to access your account from anywhere. You can do this by either using the mobile app or through a web-browser: www.qbo.ca. In case you have two-step verification enabled, it's important to note you'd still need to verify the text code on the existing mobile number or a new number.
You're welcome to ask other questions in the comments below. I'm here to help.
