Hi @YuSheng
I tried to reproduce this issue and I am not able to do that. If I am using following regular expression then I am not able to set password as "admin".
^(?=.*[A-Z].*[A-Z])(?=.*[!@#$&*])(?=.*[0-9].*[0-9])(?=.*[a-z].*[a-z].*[a-z]).{8}$
Successful: USeit21@
Failed: admin
Error reviewed while setting password as "admin"
ERROR Password violates password constraint (^(?=.*[A-Z].*[A-Z])(?=.*[!@#$&*])(?=.*[0-9].*[0-9])(?=.*[a-z].*[a-z].*[a-z]).{8}$).
