Access control system with local mobile key distribution

1. A system, comprising:

an application on a mobile device operable to communicate with an access control, the application is operable to receive a mobile key from the access control and from that to retrieve a mobile credential for authorizing a user to access the access control, the access control operable to communicate with a local portal to receive a pre-shared password based on information shared before a user's arrival to encrypt the mobile credential after generating the mobile credential to make the mobile key, the mobile key secured by the pre-shared password, the application operable to decrypt the mobile credential from the mobile key in response to entering the pre-shared password into the application, wherein the mobile key is secured by the pre-shared password and the user does not need to manage an account and associated password.

2. The system as recited in claim 1 , wherein the local portal is operable to receive a pre-shared password to encrypt the mobile credential after generating the mobile credential to make the mobile key.

3. The system as recited in claim 2 , wherein the application is operable to decrypt the mobile credential from the mobile key in response to entering the pre-shared password into the application.

4. The system as recited in claim 2 , wherein generating the mobile credential is performed utilizing a local database of encryption keys.

5. The system as recited in claim 2 , wherein generating the mobile credential is performed utilizing a centralized cloud service to which the local portal has access.

6. The system as recited in claim 1 , wherein the mobile credential is operable to operate an access control.

7. The system as recited in claim 1 , wherein the mobile credential is operable to access a service.

8. The system as recited in claim 7 , wherein the service is a thermostat.

9. The system as recited in claim 1 , wherein the mobile key is operable to reskin the mobile application.

10. The system as recited in claim 1 , wherein the application on the mobile device is operable to communicate with the local portal via at least one of Bluetooth, NFC, email, and SMS text messaging.

11. The system as recited in claim 1 , wherein the access control is operable to obtain the mobile key from the local portal.

12. The system as recited in claim 11 , wherein the mobile key is first communicated from the local portal to the access control and from thence to the mobile application.

13. The system as recited in claim 1 , further comprising a display operable to present an image to be scanned by the mobile device, wherein the image is generated based upon the mobile key.

14. A method of local key distribution, the method comprising:

receiving a pre-shared password, based on information shared before a user's arrival, from a local portal at an access control;

using the pre-shared password at the access control to encrypt a mobile credential after generating the mobile credential to provide an encrypted mobile credential secured by the pre-shared password;

communicating the encrypted mobile credential from the access control to an application on a mobile device; and

entering the pre-shared password to the application on the mobile device to decrypt the encrypted mobile credential, whereby the user does not need to manage an account and associated password.

15. The method as recited in claim 14 , wherein entering the pre-shared password includes entering a driver's license number.

16. The method as recited in claim 14 , wherein entering the pre-shared password includes entering a confirmation number.

17. The method as recited in claim 14 , wherein communicating the encrypted mobile credential includes communicating via Bluetooth.

18. The method as recited in claim 14 , wherein communicating the encrypted mobile credential includes communicating via SMS Text messaging.

19. The method as recited in claim 14 , wherein communicating the encrypted mobile credential includes communicating via email.

20. The method as recited in claim 14 , wherein entering the pre-shared password to the local portal occurs at check in.

21. The method as recited in claim 14 , further comprising communicating with the local portal to indicate a guest preference in response to communicating the encrypted mobile credential to the mobile device.

22. The system as recited in claim 1 , wherein the application is operable to share the mobile key with another mobile device operating the application.

23. The method as recited in claim 14 , further comprising sharing the mobile key from the mobile device with another mobile device operating the application.
