After weeks of eBay stressing me because I don’t have a payment method associated, I decided to do as they ask and associate a payment method. I thought a credit card would be fine, but no, they want a bank account. I start the procedure: they ask me for the bank I use, a popup from my bank opens asking me for credentials, I enter them and here, rightly, the bank asks me to agree to provide authorizations to eBay. Here I notice two things that I don’t understand: first, the authorizations that eBay is asking me to grant are related, not only to the checking account, but also to a credit card. In addition to this, which already seems excessive to me, the list of authorizations includes: coordinates, balance and list of transactions.
I could also find a justification for these requests, but more easily I see a desire to mind my own business.
