KeyHub helps teams manage keys better. A KeyHub represents a physical key cabinet. Simply add your keys to KeyHub and assign them to hook numbers. When a key is required, check it out on the app so your team knows who has taken the key and when. Daily summary emails are sent to the KeyHub Manager and, when a key is due back, reminder emails are sent to people that have checked out a key. Keys can have useful notes and a log of all key access is securely stored. KeyHub helps you keep your key inventory up to date and accurate.
