We have seen this issue occur in the Ondemand environments where you log into the portal. At times using an older password will allow you to log into Clarity via the third party applications.
Ondemand portal users access Clarity via Single-Sign On and LDAP authentication. Due to this, it is required to have external authentication enabled on all the user accounts in Clarity. If it is unchecked, passwords can seem to become unsynced, and that is why an older password may work.
