since its not possible to not have a password… the password must always have a value, the question is whether or not its the factory default value or not… i would try setting uid and otp with the password option and use the factory default password of FFFFFFFF (4 bytes all FF)
also the taginfo scan looks correct now… it has all the memory pages and settings look correct… the OTP bytes are not correct though, which carry the NFC capability container (CC) so try to get those set first then try writing.
