Set up files with passwords

The first thing we can advise you to do is simply put passwords on files which are sensitive on your computer. For this, there are several solutions.

Use word processing software

The first is through your word processing software, such as Microsoft Word for example. The method to follow is actually quite simple. Indeed, go to File, then choose to protect the file.

Protect your files with 7-Zip or Winrar

This password used previously, it is very practical, but the problem is that you can only protect Word files in this way. However, sometimes you want to protect photos, for example. For this, we will advise you to use 7-Zip or even WinRAR.

Place them on a USB key with password

If you do not want to secure your files on your computer, but rather on a USB key, it is possible. For this, you can use the previous trick and simply move the files to your USB key.

Otherwise, the other option that will be available to you is simply to put a password that will directly manage the fact of being able to open the USB key where all the files you want are located.

On Windows

If you are on Windows, the first thing to know is that you will have to go through external software to be able to do this. We therefore advise you, for example, to use Rohos Disk Encryption which is easy to understand.

Rohos Disk Encryption est certes payant, mais qu’il possède une version gratuite qui couvre jusqu'à 8Gb de données. De plus, avec Rohos, il est possible de make backups and them restore if you ever happen to delete some files by mistake.

It is a software that is quite easy to use and rather intuitive.

On Mac OS

If you are on Mac, on the other hand, you will be able to do it directly from your computer.

For put a password on your USB key, so there is nothing very complicated.

  • Take an empty USB key and delete it.
  • Then choose to put it in Mac OS Extended format
  • Open Finder and right-click on the USB drive.
  • Choose Encrypt "USB Drive".
  • You will then be asked to enter a password and you will be done.

Protect your files with the cloud

The other solution for protect your files, it's the cloud This solution has an advantage that is still more than interesting. Indeed, it does not require any complicated handling.

So, if you're a bit afraid to get your hands dirty in the settings to set up passwords, the cloud may prove to be the almost perfect solution for you.

Indeed, you will be able to use this cloud to protect your photos and guarantee you the only access since you will have to log in to your account to be able to access them.

But on top of that, you will be able to save space on your computer and on your Android phone or iPhone.

Indeed, the whole principle of the cloud is to put files on remote servers. It is therefore a solution that has many advantages and if you want to test it, know that it is possible.

Indeed, there are several sites that offer this kind of service. Among them are in particular:

These cloud services will put in place what is called a encryption which will make your files completely unreadable in the state. Therefore, if you do not have the encryption key on you, it is simply impossible to read file.

We are therefore clearly a step above the simple security of a password. Indeed, a password can be hacked and if you are not careful in multiplying them for example, it is even quite easy to find.

On the other hand, ciphers are clearly impossible to overcome without the key. Therefore, it is undoubtedly possible the safest way to protect your important files.
