Show tooltip

[TechAspirant]

I want to show tooltip along with Hint in validation rule in form field.
Say,
When we create user and If confirm password is mismatched with password field than It shows validation error with hint.
And when user click on 'Save' it show the tooltip saying password enrty didn;t match.
I want to show this tooltip when the validation error with hint appears instead of 'Save' button click event.
