It happend to me recently that I became the owner of a new laptop.

One of the nice things about it is, that it has a fingerprint reader which simplifies my life tremendously.

Though everyone should be familiar with fingerprint readers these days, there are some caveats to be aware of. My friend kybernetikos was kind enough to point out one of them:

For safety/backup reasons always store at least one fingerprint of the other hand!

So far so good, but why stop here when you can even have no hand authentication:
