I am trying to set up a Microsoft account to access Cortana, but MS keep on rejecting my password because of unacceptable characters. The password I want to use (I will change it) is Wacfr0[Live0] - it has at least 2 upper case characters, at least 2 lower case characters, at least 2 numerals, and at least 2 special characters, is more than 8 characters long, and is less than 16 characters long. According to Microsoft, the square brackets are permissible special characters. Can anyone tell me what is wrong with the password? Banging head on wall time.
