SMMC's NetLearning is not a part of Cerner, so it requires its own unique password that is not related to your routine password used for Cerner or Email.
Welcome1 is the default "current password" UNLESS you have changed it. If you are asked to change this "current" password to a "new" password", and have not logged in before use 'welcome1' as your old password. This new password that you set will not expire.
If you still cannot log in, click the FORGOT PASSWORD button and check your WORK and HOME email address for the response.
