Revoke the access token supplied by —access-token, FLY_ACCESS_TOKEN, or
FLY_API_TOKEN, including all tokens in a token bundle. Uses —access-token first,
then FLY_ACCESS_TOKEN, then FLY_API_TOKEN. An explicitly empty FLY_ACCESS_TOKEN
prevents FLY_API_TOKEN from being selected.Use ‘fly auth logout’ to revoke the access token saved by ‘fly auth login’.Does not clear local configuration or unset environment variables.
