A lock system includes a processing circuit. The processing circuit is configured to store an access credential for a locking device. The access credential is associated with a user. The access credential has a lifespan. The processing circuit is further configured to deliver the access credential to a user device associated with the user to facilitate accessing the locking device with the user device, monitor a frequency at which the user device accesses the locking device using the access credential, and adjust the lifespan of the access credential based on the frequency.
