eBay, for the love of Cyber Security, allows us to register more than one PassKey. I have no idea why you thought it was necessary only to allow 1 key when it's advised to register more than one. This is the industry standard. It seems like whoever implemented this knows little about this security method and needs retraining. Please investigate this internally and let us secure our accounts better.
