Tuna Day, Star Wars Day, Nude Gardening Day – just a few
of the countless 'days-of' you could be celebrating these days. Some days may
appeal to you more than others, but the day I want to talk to you about is World
Password Day. That day was created in 2013 by tech company Intel “to raise
awareness about the role strong passwords play in securing all of our digital
lives”
So the password has its own celebration, but it is also
maligned. You have too many of them, they have to meet all kinds of complicated
requirements, you forget them, they want to be refreshed regularly and they are
far too important for the security of all those accounts. Isn't it time for the
password to give up that important role that Intel assigned it almost a decade
ago? In favor of something easier and safer?
Look around you. It's already there. How do you unlock
your phone? You can do it very easily with your fingerprint or with your face.
Your fingerprint is more secure than a PIN, because no one can copy it. And
yes, I am aware of those James Bond scenarios where fingerprints are taken from
a beer glass with tape and then imitated in latex, but mere mortals really
don't have to worry about that. Officials, for whom these kinds of high-tech
attacks can pose a threat, are aware of this all too well – I hope.
Consumer-grade facial recognition, as used in mobile phones, is often still too
easy to get around with a photo, so I don't recommend using it for
business/important applications.
Microsoft has been promoting 'passwordless
authentication' for some time: the system can determine that it is really you
without the need for a password. For a year now, business users have been able
to log into Outlook and OneDrive without a password. Instead, they use the
Authenticator app, Windows Hello, a physical security key or a verification
code that you receive on your phone or by email.
An authenticator app (not only from Microsoft, but also
from Google and RSA, for example) generates a numerical code for every account
that you protect with it, which is usually valid for one minute. You must enter
this code when logging in. Currently, we mostly use this mechanism in the
context of multi-factor authentication (password + something extra), but
Microsoft wants us to get rid of the password entirely with this.
Windows Hello, for example, works with an infrared camera
that, among other things, looks at the thermal image of your face, the distance
between your eyes and the depth of your eye sockets and the position of your
mouth and nose. Without taking pictures. You can also use a PIN instead of this.
Huh? Isn't a PIN more insecure than a password, because you only use ten
different characters? For starters, the Hello PIN does not have to consist of
only numbers, but more importantly: the PIN is linked to a specific device, for
example your laptop. Moreover, the PIN is not something like a surrogate
password, but a code to unlock your own secret key. Using that key, a
cryptographically secured login request is sent to a server. Your PIN itself
will not be sent. And there is no server where your PIN is stored. This is
different with passwords: at an online store they know your password because
they have to be able to check it. That's why the world is always in turmoil
when a large company's password file is stolen.
Windows Hello is just one example of a passwordless
future, chosen here because I think there's a good chance this will be - or
already is - your first experience with it on a computer. In order to be
comfortable using such technology, it is important that you have some
understanding of how it works. A few years ago, when I unpacked my new computer
and Windows 10 wanted me to make up a PIN instead of a password, I too thought
that was weird. But with some explanation, the puzzle pieces fall into place.
Many properties of passwords have become obsolete, such
as complexity requirements and the requirement to change them regularly. We can
modernize those features, but we can also take a big step right away and do
away with passwords altogether. Intel, which came up with this theme day, is
also participating in the FIDO Alliance, a worldwide group in which technology
companies work together on a strong way to authenticate users without
passwords, because they believe in its security. We are moving towards easier,
safer times. But in the meantime: use a password manager, which makes up and
stores passwords for you, and which logs in automatically for you. That is
always safer than messing around yourself. Because that's just what we humans
usually do when it comes to passwords.
And in the big bad world…
… a lot has undoubtedly been going on again, but this
week I didn't have time to select that information and present it here.
