Hi vanz_syah,
Thank you for reaching out to us on the Microsoft Q&A forum.
Yes, you can absolutely use a different Azure account to do the hands-on exercises in Microsoft Learn. For example, if you are using email A as your Microsoft Learn account and email B as your Azure account, that combination will be okay.
Just ensure that the Azure account you select has permissions and access to the resources that you will be utilizing throughout the exercises. This will make learning seamless as you work through the modules.
In case you have any other questions or need help with anything else, kindly do not hesitate to ask. Happy learning!
