Techniques for personalizing short-term session credentials are described herein. A global session key is provided to a plurality of regions of a computing resource service provider and an account key is also provided to one or more of the plurality of regions based at least in part on those regions being trusted by a customer of the computing resource service provider. When a request for short-term session credentials is received at the trusted region by that customer, a session token is generated and encrypted with a combination of the global session key and the account key, thereby creating a session token that can be uniquely associated with the customer and that may only be used in regions that that customer has designated as trusted regions.
