It's a little confusing that the description here is the same for the string
above. I think the string above is a little bit more explanatory, so maybe we
should ask UX if it's okay to resuse it? Otherwise, enhance the description so
it's clear how these two differ.

Ah, sorry, the IDS_PASSWORDS_ACTIVATE_DEVICE_LOCK was also added by me in a CL
that this CL depends on, I've just removed it as after discussions with the UX
designer we've decided to use the latter string.
