Doorcodes are unique and created directly by Latch. When a Doorcode is assigned to you in the Latch App, you are the only one who is given this specific doorcode.
If you would like to change your Doorcodes, please reach out to your property management team and ask them to revoke all of your current access and then re-grant it, as this will generate a new Doorcode(s) for your account.
Please note that to ensure that the prior Doorcode(s) is no longer valid on any non-internet connected Latch devices (such as the one on an apartment unit door), a door update must be performed once you are re-invited to access your doors with the Latch App.
