You've seen the following announcement show up in your Launchpad notifications. But you want to confirm if this means you have to redo all the MindConnect Lib connectivity for validating access token.
MindSphere Security Keys

We are going to update certain security keys that are used for signing the tokens used for the authentication and authorization of Applications and MindSphere API calls. This change will happen on January 30th for the EU1 platform. Please see https://developer.mindsphere.io/concepts/concept-key-rotation.html for additional information and prepare accordingly.
Solution
MindConnect Library does not validate access tokens, it only uses them. This update of security tokens will not affect MindConnect Library.
For old tokens validated by MindSphere - MindSphere will use new keys to sign new tokens but it will also keep the old keys to validate the tokens signed with old keys until the old tokens are renewed.
Notes
@Mike:- I have confirmed this with the mclib team.
