Customer create account error message

Hi, I have edited my customer account creation page and added a password verification, I have edited the placeholder to inform the customer that passwords need to be "Min 8 characters, uppercase, lowercase and a number". I want to change the error message if possible as when a user starts to type in the password box the instruction from the placeholder disappears and if the passwords don't meet the complexity set the message just says "Match the requested format", I would like to change this to "Please ensure your password contains a min 8 characters, uppercase, lowercase and a number" or something similar.

If the password does meet the complexity but doesn't match, the error message is correct, displaying "Passwords do not match".

Is this at all possible?
