Also ...

In the case of passwords, if they're properly stored, the data steward
doesn't really know what's in them.  But they *could* have SSNs, email
addresses, DOBs, etc. in them (and very often do).

So I would expect any data steward worth their salt to err on the side of
caution, and *assume* that what's in there is sensitive enough to warrant
GDPR-level handling.

And honestly, that's the level of handling that it requires even if it's
*not* within GDPR's scope, IMO.
