Is it Safe to share GST details with CA from Amazon FBA?

Hi, I am a new Amazon seller. I wanted to join the FBA so I have paid 800 Rs for the service. I am now contacted by a CA who is asking me to share GST details(Login and password) as well as NOC and BSA

My question to all experienced FBA sellers is whether it is safe to share these details with anyone? Is this the regular process- please guide.
