Accountant log in?

Hi all
I have been selling on Amazon for a year and have just appointed an accountant. She would like to be able to log into my Amazon account and I am quite happy for her to have this access
My question is, is there a way for me to create a new log in for her with an email address and password she will provide? If so how?
I could obviously give her my email address and password but I would prefer she has her own
Thanks
