If you remember in Cognos 8, you had to update credentials everytime in schedules after changing your login password otherwise schedules would fail. If not, here is the link to refresh your memory (if you are still on Cognos 8)

However, since this was kind of tedious job if you had large number of schedules defined. In Cognos 10, this wasn't required as it was designed to automatically renew credentials. However, there have been cases, where this was misunderstood. We came across one such occasion and had to publish a technote clarifying the concept of automatic renew of credentials in IBM Cognos 10.
You can read the technote here.

Funny thing, you could turn this good feature off too ;)
