User Authentication Process | Continental/Vitesco
The client, responsible for the electronic control units' reprogramming,
required the software to skip the authentication process of the toolchain
user in certain circumstances where the user authentication is not
relevant.

L Improved by 3x the user experience with authentication by implementing
a strategy of skipping the user authentication and granting the user
access in those circumstances.

L Decreased the interaction time by up to 10% by avoiding the processing
of a dummy certificate sent by the user of the reprogramming toolchain.

may affect either the product owner or the producer.

L Reduced risks by more than 90% by implementing the software
mechanism that deals with the microcontroller capacity of preventing
unauthorized access to its memory and access ports.

L Increased by 2x the experience of the user by implementing a software
module that lets the user exchange the setup data in a compact and easy
way.
