Is there anyway to update credentials for gateway accross multiple datasets?

[Pointed_Insight]

I have set up multiple data sets that are updating through a personal gateway running on a virtual machine.  My company requires that I update my password every 90 days.  Each time I update the password my credentials need to be updated on the datasets. 

It seems that I need to update the credentials for each dataset separately.  Is there a way to update all the credentials with a single update to my credentials?  I will eventually have many more data sets and this will become a cumbersome issue.

I'm using the personal gateway.

Thanks
