It may be nonsense, but it certainly isn't equivalent to saying "my pen
is my name". Pens can write all sorts of things, and are fairly
indistinguishable from other pens. The same cannot be said of keys.
Saying "my key uniquely identifies me" strikes me as reasonably valid
(with some provisos), whereas saying "my pen uniquely identifies me" is
Now, if you want to argue about whether a unique identifier can
reasonably be called a name, there may be some grounds for that
argument. But I can't see that it is in the slightest interesting.
