I found an article about how to enable U2F login in Ubuntu here https://shibumi.dev/posts/login-via-yubikey-on-linux-u2f and also from Ybikey site https://support.yubico.com/support/solutions/articles/15000011356-ubuntu-linux-login-guide-u2f

Procedure was really easy so here are the steps:

install U2F pam module
sudo apt-get install libpam-u2f

Create folder for the keys
mkdir ~/.config/Yubico
This folder might be already present
create first key entry
pamu2fcfg > ~/.config/Yubico/u2f_keys
You can insert your yubikey and touch the metal and key is written to the file

Enabling U2F for sudo:
Edit the file
sudo vim /etc/pam.d/sudo
and after the @include common-auth line add
auth       required   pam_u2f.so

Now you can open new terminal window and type
sudo echo test
It should ask your password and then waits for the yubikey to be pressed.
After you touch the metal on yubikey, sudo should work

If you want to enable U2F for graphical login, add the following line to your DisplayManager's config in /etc/pam.d folder after @include common-auth
auth       required   pam_u2f.so

Adding backup key

I have another key that supports U2F and it's solokeys https://solokeys.com/
Only thing you need to do is insert another key to ~/.config/Yubico/u2f_keys file
pamu2fcfg -n >> ~/.config/Yubico/u2f_keys
Notice the slightly different command (the -n parameter) and >> means you append the file, not write over

#yubikey #2fa #solokeys #ubuntu #U2F

PSA: MyFitnessPal has been compromised leading to 143M accounts to have their weakly hashed passwords, usernames, email addresses and IP addresses leaked.

Considering that UnderArmour owns MFP, and that password resets go through your UA account, I would garner to say that you should change your password if you're signed up to any of the UA-owned services.

Currently my node is aware of 3575 nodes with 2496169 registered users from the following platforms:

Friendica (359/13545)
diaspora (262/655654)
red (8/72)
hubzilla (224/4807)
GNU Social (183/420)
StatusNet (9/11)
Mastodon (2237/1817064)
pleroma (288/3729)
socialhome (4/730)
ganggo (1/137)


Thinking of something quick weekend project for my server.
It already has the following

Not going to have mastodon or diaspora for now

Most of these are not in “production”. I use mostly nextcloud and hubzilla. Others are there just because.

Or I go to hw project and try to put some free os to Apple iBook G4 laptop.

Libre of a different kind to start off my Friday.

Hello I just made an account here.

I'm a big fan of software.
I have been using since 1998 and I host some servers for my own purposes.

I like tinkering with different kind of software, but I don't know how to code.


Fosstodon is an English speaking Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
