The current feature to share passwords with someone else with an expiry date is very useful. However, the maximum 30 days expiry is quite limiting if one wants to share a password in case someone dies or changes responsibilities and is no longer interested in maintaining access to the service protected by the password.

With a 30 day expiry, one has to remember to reshare the password regularly, which may be fine but 30 days means one would have to share again every month or so. Best would be if there were another mechanism.

Either extend the potential duration to, say,. one year, where the user could put a reminder to reshare in a year or allow for some form of "user is deceased or is not available' type of recovery. Maybe something like a recovery code that can be used to recover a password or set of passwords that were shared. If someone requests recovery, first inform the user that recovery has been requested and, if the user does not take action within, say, a week, allow recovery.
