Thanks for the feedback all! Bitwarden is working towards a vault health dashboard-type experience to provide automated reporting.
Regarding changing your passwords for you automatically (in single or bulk), for the time being, this will require user intervention as not all websites would be compatible with this method as they are designed with vastly different approaches/standards.
Rest assured, the feedback has been passed to the team and we will continue to monitor standards in this space and find ways to improve the experience.
