Computer security is not something to be taken lightly. On the contrary, it is good to take measures that favor the protection of our confidential information. So, many people prefer to use a password manager to keep all their online services secure.

While on the internet I met Buttercup. A very sophisticated, modern, and simple password manager available for Linux. Actually, it’s multiplatform, so there are versions for Windows and Mac OS as well.

Buttercup uses very strong encryption to protect your sensitive details under a single master password. It also has an application for mobile iOS and Android that gives you access to the same archives you use on the desktop application.

On the other hand, Buttercup can be installed in Google Chrome or Firefox as an add-on, thus increasing the possibilities of operation.

The application uses strong 256bit AES encrypted archives that meet today’s security standards. So, you don’t have to worry about the security of your credentials. Another great feature that Buttercup has is its ability to integrate with Dropbox, Next cloud or Owncloud.

So, let’s use it.

Download and Install Buttercup

Installing Buttercup on Linux is very simple. It has installers for deb distributions (Debian, Ubuntu, Linux Mint…) and for rpm (CentOS, OpenSuse, Fedora…) which makes it usable for a large number of people.

First of all you have to download the corresponding file.

In my case, I’m using Debian 9, so I downloaded the .DEB file. If you use Debian, Linux Mint 19, Ubuntu 18.04/18.10 or one of its derivatives, then you must download the .DEB file. If you use CenOS, OpenSuse or Fedora or some derivative of these Linux distributions, then the option to choose is the .RPM file.

Next, open a Terminal and type.

For Debian, Linux Mint and Ubuntu:

As this is the first time you use Buttercup, you don’t have a file available. All encrypted passwords are stored in that file. If you have one, you can import it from the cloud or locally. In this case, I’ll create one.

Then, the program will ask you to give it a name. Then, enter a master password to protect the file. It is recommended that it be quite strong.

Finally, you can connect with online services. Go to File menu and click on Connect cloud sources option. This is useful because you can save the file on one of this service.
