Why a four-digit PIN is sometimes more secure than a password

A password may not always be more secure than a PIN, even if it seems obvious. We show you a situation where the PIN clearly wins.

No one would say that a 4-digit PIN can be more secure than a 12-character password. (of which half are strange characters), but the truth is that it is so. That is, only in some cases and under certain circumstances, since it is clear that the complexity of a well-crafted password can offer us much more security than a simple combination of 4 numbers.

To put ourselves in a situation, think about the password of Facebook, Instagram, Twitter most likely the password is the same. Not yet sindolo, it is very exposed, because we are from the mobile phone, from the PC, or even from a cyber, we will have to enter it. This implies that if there is akeyloger on any of these devices, rest assured that the person in charge of having installed it there will be able to have full access to the account of that social network.

A PIN may be more secure

A PIN, on the other hand, should be unique to each of thegadgets.That is, we will have to use a PIN for thesmartphone, one for the computer, and one for whatever. We should never put a PIN that we have used anywhere else. And it is that the question is here: if we put a password instead of a PIN, it is most likely that we will use that same password for any other account, so that if exposed, our computer would also be.

Now let’s imagine a much more specific situation: imagine that we have a Windows computer. To log in we will have to put the same password that we use in Outlook, well it works in the Microsoft operating system. We return to the same as before: if by any chance our email account has beenhacked, our computer completely be in danger.

This is where the PIN comes in, because if we use an exclusive one we will avoid precisely that. Of course, PIN is not the safest method, it is clear, since this position is currently occupied by biometric authentication systems (a fingerprint sensor, for example).

Now we can think: if we put a unique password for each of the services and for each of our devices, be as secure as a unique PIN. This is true if we are on Android, for example, but not if we are on Windows, where the password, much of the time, has to be the same as email, otherwise we will not be able to synchronize the information.
