From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Issue with 2FA on Fedora/GNOME logging in (lemmy.one)

I already use 2FA to SSH into Fedora with libpam/google-authenticator.

I also tried setting it up for GNOME desktop login. However, after logging out and going back to the login screen, I type in the 2FA code (which it accepts fine via SSH) and it says it is incorrect. I have a feeling SELinux is messing it up. Luckily I could SSH back in and fix it back.

Anybody have any experience with this?

Did you try parsing journalctl over SSH and check to see if there were any PAM or SELinux errors?

I'll do that first thing tomorrow and report back

You can also run setenforce 0 to temporarily disable SELinux and rule that out.
