Password Management Applications?

I have some passwords that are long, complicated and hard to remember.

I would like to use a password-manager application to save all of my passwords instead of saving them using a text editor.

What is the best password manager?

KeePassX

KeePassX is a free/open-source password manager or safe which helps you to manage your passwords in a secure way. You can put all your passwords in one database, which is locked with one master key or a key-disk. So you only have to remember one single master password or insert the key-disk to unlock the whole database. The databases are encrypted using the algorithms AES or Twofish.

I suggest you the free, cross-platform KeePassXC, a fork of KeePassX. I'm using its DB on my Android phone too (KeePassDroid, combined with Dropbox).

Seahorse is an application that is installed in Ubuntu by default and manages passwords for various applications.

I really like LastPass It's not open source, but is very well supported across platforms, browsers and devices. They recently acquired XMarks (great cross platform/cross browser bookmark sync tool). LastPass is incredibly secure, offers 2nd pass authentication and is very reliable.

KeePassX is another option:

KeePassX is an application for people with extremly high demands on secure personal data management. It has a light interface, is cross platform and published under the terms of the GNU General Public License.

KeePassX saves many different information e.g. user names, passwords, urls, attachments and comments in one single database. For a better management user-defined titles and icons can be specified for each single entry. Furthermore the entries are sorted in groups, which are customizable as well. The integrated search function allows to search in a single group or the complete database. KeePassX offers a little utility for secure password generation. The password generator is very customizable, fast and easy to use. Especially someone who generates passwords frequently will appreciate this feature.

The program is available in the Software Center but I can't figure out how to make a nice install button which works :)

KeepassX is also available for Windows and MacOS.
