As pointless as a chocolate teapot
FWIW, my password is complex & unique to my Google account and having to wait for a one time password to login on the only 2 systems I ever use seems quite pointless.
Better to enable it only if its not one of your regular machines.
And I can't see anyone who needs to use it (because they have a weak password) actually enabling it.
