eBay offers support for registering a FIDO 2 security key (e.g. Yubikey) for passwordless login. Unfortunately it seems that you can only register a single security key, meaning that if you lose or break your key, you may be locked out of your account. What's worse, eBay does not provide even provide a backup code. This effectively renders this feature useless, since I cannot reasonably risk losing access to my account even for this added security. Are there any plans to extend this feature to support multiple keys?
