Therefore, IN-CORE’s user management system will use Keycloak technology going forward which requires all current IN-CORE users to reset the passwords to their accounts. Please follow the instructions below to reset your password and ensure that your IN-CORE account will be registered under the new user management system. Failure to do so will disrupt your access to IN-CORE and your data.</p><p>The IN-CORE Dev Team is requesting you to update your {2} account by performing the following action(s): {3}.
