I was prompted to create a distribution key when registering my app for TestFlight. I clicked away from the save screen and never set a password as I wanted to double check the key name.
I've since deleted that key from Keychain Access and have tried to recreate it. Generating a new certificate/key from Apple Developer, I can't export the key from Keychain Access because it asks for a password - the same password I never created.
Looking for the next steps here to regenerate/export/save the key so I can move forward.
