How to factory-reset your Ring video doorbell in two steps

Resetting a Ring video doorbell is a simple process that can be completed in just two steps. Before you reset your doorbell, however, it's important to note that doing so will delete all of its settings and erase any recorded footage. It's also important to have your Ring account information on hand, as you will need it later to set up your doorbell after the reset in order to use it again.
