No, absolutely not.

It shouldn't matter what malware is on a client device as long as the client has authenticated; the server/company/ebay should be protecting their API from abuse at the API layer, not the client layer.

I think what you’re saying is the user might be an employee on some internal trusted company network. The employer should have control of that browser (and entire endpoint), otherwise the network should likely not be considered trusted. So, in this case, no, the user shouldn’t have the ability to authorize this; the administrator of that browser should.

Know your network.
