@YouInMyEye I don't think there's any replacement policy through Yubico. It's always good to have two anyway. One as your main, the other as a backup stored somewhere safe.
@YouInMyEye I have three all set up identically with 2FA for as many accounts as I can. Two are new Yubikey 5 series NFC, so they work with my phone, and one is an old #Yubikey 4.

Nice!
Mine is in my keychain without any protection. I hope it's okay. Don't they have a replacement policy or something?
