I am locked out of Amazon because I do not know my passkey for firefox/mozilla. I didn't know I had one and I don't know where to find it. Can you help me?

A passkey is an alternative to a traditional username/password pair. If you don't remember setting up a passkey for Amazon, then you should still be able to sign in using your username and password. (If Firefox shows an option to use a passkey, please ignore it.)
