You must have seen the login or signup form where we have to fill in our name/username, email, and password from our keyboard, and the UI shows whatever you enter in their respective fields but not in the password that is obscured from us. Also, if a field doesn’t fulfill the validation, the respective field will throw an error with an appropriate message, like password is too short.
