Was excited to learn of the free Developer's access to Wolfram Engine, then disappointed when I couldn't activate the product from Windows (by providing the username and password in the wolframscript terminal). I kept getting a complaint that the username/password was incorrect. I know this is usually user error, but I tried enough times and ways of entering to dismiss that. Then it occurred to me that maybe Wolfram were scrubbing the input in the password field, removing what are in some contexts dangerous characters. I changed my pw to a long alphanumeric instance and the activation worked first time.
