You wouldn't edit this. You would add additional validations. This is the Like Entry validation.
You would add Regular Expression validation the the password field for the additional validation requirement:
Some regex values you might use are:
Minimum 8 characters at least 1 Alphabet and 1 Number:
/^(?=.*[A-Za-z])(?=.*\d)[A-Za-z\d]{8,}$/
Minimum 8 characters at least 1 Alphabet, 1 Number and 1 Special Character:
/^(?=.*[A-Za-z])(?=.*\d)(?=.*[$@$!%*#?&])[A-Za-z\d$@$!%*#?&]{8,}$/
Minimum 8 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet and 1 Number:
/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)[a-zA-Z\d]{8,}$/
or
/^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,}$/
Minimum 8 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet, 1 Number and 1 Special Character:
/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])[A-Za-z\d$@$!%*?&]{8,}/
Minimum 8 and Maximum 10 characters at least 1 Uppercase Alphabet, 1 Lowercase Alphabet, 1 Number and 1 Special Character:
/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[$@$!%*?&])[A-Za-z\d$@$!%*?&]{8,10}/
I just found these on the web so I haven't tested them, but people seem to have had success with them.
