Temporary password to change beacon settings

So if I can’t remotely change the Eddystone URL, power or interval using my Estimote Cloud - Is there a way to give a client a temporary code so they can change those settings?

Example- I have a client in Ohio who I shipped a programmed beacon to from my business in California. I inserted a certain URL before I shipped it off. But now the client wants to change that URL to something else. I can’t do it because I’m not in range, but he could. But I don’t want to give up ownership of the beacon and I don’t want to give him my password info to make the changes. What is the best way to handle that?

Thank you…

I’m sorry, to clarify… can I give the client a temporary password to make the changes. Thanks,
