    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

    Bloody Profanity

    Fingerprint-only auth screen for KDE/Plasma

    Lock screen with fingerprint authentication via fprintd. Currently, only fingerprint authentication is supported. DISCLAIMER: This lock screen uses adult language, and literally gives you the finger upon auth failure, so be warned. All images and random phrases can be changed by creating files under the .BloodyProfanity directory. Files that can be overloaded include: .BloodyProfanity/conf/sarcasm.yaml # random fail messages, begin every line with '-' (see yaml docs for more) .BloodyProfanity/img/bg.png .BloodyProfanity/img/error.png Other settings can be changed by editing the globals near the top of locker.py. REQUIREMENTS: KDE, PyYAML, Subprocess32, wxPython, fprintd and of course Python. INSTALLATION # As root b=/usr/share/BloodyProfanity cp -rvp /path/to/bp $b g=/usr/lib/kde4/libexec/kscreenlocker_greet cp -v $g $g.bak cp -vpf $b/locker.py $g # As user fprintd-enroll fprintd-verify # important mkdir -p ~/.BloodyProfanity/conf ~/.BloodyProfanity/img
