Password managers are very interesting tools and used by users. They allow us to manage our keys and have them all available without remembering them or saving them in insecure sites. We have a wide range of possibilities in this regard and many options to use. Some of them are free, others are paid, sometimes multiplatforms … In this article we are going to talk about some open source password managers . A selection of those that seem most interesting.
Why use password managers
We live in an era where we have many passwords in our day to day. We have to manage a large number of keys daily. Each registry, each account we use on the Internet, has a password to access. If we do things well, the ideal is to have a unique password in each case and that is also strong and complex enough not to be easily ascertained.
This makes it difficult to manage so many keys at the same time. It would be common to forget especially those accounts that we barely use. Luckily for this there are the password managers that help us manage them and not have to remember them all.
But they are also very interesting to generate the keys themselves . Many of them offer us the possibility of creating keys according to criteria that we mark.
Open Source Password Managers
We have indicated that we have at our disposal a wide range of possibilities in terms of password managers . In this case we will show a list of those that are open source. We already know that this peculiarity is usually very well valued by users when using software.
KeePass
One of the options we have for open source password managers is KeePass . It is undoubtedly one of the best known today. It is available for different operating systems such as Windows, Linux, macOS, iOS or Android, which are the most used.
It also offers a series of very interesting integrated security functions. One of the strengths is also that it does not need installation, so we can simply run it from a pendrive. It uses 256-bit AES encryption with SHA256 HMACOs. 
Buttercup
Another open source alternative that we want to show is Buttercup . This is a key manager that also uses 256-bit AES encryption with SHA256 HMAC. It has as one of its strengths to offer total control to users over where the keys are stored. In this way we can use our own system or allow them to be stored in services such as Dropbox or Google Drive.
Therefore Buttercup is an interesting option if we are looking for an open source password manager that also has different functionalities. We can even generate passwords.
Passbolt
We also found the option of Passbolt . It is a key manager designed specifically for computers, since that is where it stores passwords. We can host the keys on our own servers and we have total control.
Again we have a free and open source password manager. We can see more information on their page .
Bitwarden
A very popular password manager that cannot be missing from the list is Bitwarden . It is available in desktop version and also as an application for iOS and Android. It should be noted that this option is designed for individual use and also for groups. We can therefore share passwords and files with different groups.
In addition to the versions for operating systems it also has extensions for major browsers such as Google Chrome, Mozilla Firefox, Opera or Safari. This makes it have a great integration.
Teampass
Teampass is another option to use an open source password manager. In this case, it is a key administrator who is mainly team oriented. An interesting way to have the keys available for several users.
