Password must be at least 12 characters long, must include lower and upper case letters, must include numbers, must include special characters, must have at least 3 numbers, must have at least 2 special characters, may not include words in the dictionary. Your password is rejected because it does not comply to our policy. A policy that isn’t published anywhere, but you must make one that complies anyway. Your password has expired, make a new one that does not resemble any of the passwords that you have created in the past. And it’s all useless. We’re all doing it wrong.
