- COSIC-developed mobile authentication technology nextAuth acquired by itsmeitsme®, the Belgian identity app that is currently being used by nearly 7 million Belgians, has acquired the Leuven-based company nextAuth. NextAuth, which specializes in highly advanced cryptography, is a spin-off of KU Leuven and imec and originated in COSIC. “We are often asked questions about the difference between nextAuth and itsme®. Our answer has ...
