SWIFT Secure Signature Key (3SKey)

In partnership with Citi and other member banks, SWIFT developed this multi-bank and multi-network personal digital identity solution using a single signing device to allow corporates to sign financial messages and files sent to their banks. It also offers banks a cost-effective way to implement secure authentication on electronic banking services by using a shared, reliable and trusted Public Key Infrastructure (PKI). 3SKey is usable on the SWIFT network and on any proprietary networks or the internet.
