I noticed that when logging in to idmsa.apple.com, my old email address still appears as an option, even though I’ve updated my Apple ID to a new email. I understand that passkeys rely on a public-private key pair, with the public key stored on the server (e.g., idmsa.apple.com) and the private key saved locally in iCloud Keychain.
Could you please clarify: 1. How can I request Apple to delete the public key associated with my old email address from their servers? 2. Is there a way for users to manage or update server-side passkeys without contacting Apple support? 3. Does this behavior affect my account security in any way?
Any advice or insights would be greatly appreciated!
