Please read “Getting started with Flatpak“. In order to enable flathub as your flatpak provider, use the instructions on the flatpak site.


Authenticator is a simple app that allows you to generate Two-Factor authentication codes. It has a very simple and elegant interface with support for a a lot of algorithms and methods. Some of its features are:

    Many thanks, useful selection!

  2. Darvond

    So between Google-Authenticator, totpcgi, Numberstaton and this one, what would be the vying pull for the double library bloat of Flatpaks?

    Also Secrets is also in the main package repository, why bring it up?

    The latter two aren’t in the repos, but Pomodoro timers aren’t hard to find. There’s 8 on Fdroid, probably countless more on the mainline app stores.

  3. Joerg

    Thank you for the information about recommended apps. I’ve been using Fedora for about a year now and I’m impressed by its up-to-dateness, stability, and speed. The regular news from the Fedora community is very interesting.

    Helpful article as always! Minor typo in the last entry 😀 Change “Flatsweep” to “Solanum”.

  5. Axel

    Great article! One addition that could be made is FlatSeal, a tool used to manage directory access and permissions other flatpaks have.

    Why do we need multiple app distribution mechanisms?

    • Darvond

      Mostly to solve the issue that people think that to make Linux appealing for “regular” people, something needs to be done to make the “Padded Cell” take place. I don’t think changing the distribution methodology is near the top of the actual issues.

    @hf, interesting content from these links. Did not know (too much) about it.

    For my part I usually install everything from the package manager (DNF). The only exception here are Wine-based applications (through Lutris and Steam), where I indeed use flatpak for. The purpose here, however, is less about the security aspect than separating the many 32-bit components from my otherwise pure 64-bit host system in hopes to have it run smoother or with less problems. Whether this is perceived or real should likely be discussed elsewhere.

    Though after having taken in the content of these links, I also agree with the suggested changes proposed in “Is Flatpak Fixable?” from the second link. It would provide a good future to flatpak and its applications. While it may put some load on the developers, the result would be a tremendously better user experience on the long run and as a user myself can only plea to the flatpak developers to reconsider. It will surely pay off.

    Better create an rpm, i do not like packaging formats, that reminds me of windows.

  9. james sparks

    thanks for today’s upgrade to the wifi driver!

    What’s the reason that the flatpak commands do not properly uninstall packages but create the need for another app to clean up after them?

    • Don Joe

      Would love to hear why flatpaks dont get unistalled completley to use Flatsweep ?

      As well as why should we use Flatseal permissions…

      Why devs dont lock down flatpak app permissions for user ?
