KeePassXC Password Manager For Linux project started as a community fork of KeePassX.
It is built using Qt5 libraries, making it a multi-platform application which can be run on Linux, Windows, and macOS. KeePassXC uses the KeePass 2.x password database format as the native format.
Basically, if you have a bunch of passwords, for different sites, banks etc, this tool comes in handy. You just need to remember one password to open up the KeePassXC and access the password you need.
Linux Memory Protection:
The program prevents the use of ptrace and generation of core dumps. This prevents anyone, except the root user, from accessing the memory of the process.
Due to the significant variety in different Linux distributions, we encourage you to ensure the kernel is compiled and run with sufficient protections to process memory.
The Snap and Flatpak distributions of KeePassXC run in their own sandbox (on Debian / Ubuntu) which significantly increases their memory security.
The AppImage distribution can be further secured by running it in FireJail. If you are concerned with memory attacks, we recommend using these distributions.
KeePassXC Version 2.7.4.
For Debian 11 or LMDE5 there are 3 alternatives:
