To provide the context, we have updated our password policies to disallow commonly used passwords like “Password1”, “Welcome123”, football teams, first names and easy to type keyboard sequences etc. and we would like to provide a specific error message so that users are aware of why even after having the required pattern being followed we are not allowing the input password.
So now, although we would like to provide relevant details however at the same time we don't want to provide a huge message which in turns become a bad user experience and the fact that it will be impacting large number of users, I just want to ensure that it is delivered in best possible message. All inputs are welcome and would be happy to provide further details if required.
