Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

- I have seen in a lot of posts here people say not to use Google Authentication for 2FA. Can someone simply explain why, and what should I use instead?

LUKS with Yubikey
Would using this be possible? https://github.com/agherzan/yubikey-full-disk-encryption/tree/master/src

Getting LUKS, Btrfs, Hibernation and Swap file working in tandem
> Hibernate is less interesting, and apparently unsupported using secure boot anyway.
That's not the case. I have a similar setup to yours (/ on ext4 with separate swap, on LVM on LUKS, separate /efi) and my box hibernates just fine with secure boot and auto-unlock via TPM.
The difference with your setup is I don't use grub, but have the UEFI load a signed unified kernel image directly. Since this works so well, I never had a reason to mess around with yet another moving piece (grub or other bootloader).
As another commenter said, I haven't attempted to mess around with the MOK. I just replaced all the secure boot keys with my own, and I've also signed MS's Windows key (but not the 3rd party one) for my dual-boot needs.

For specifics: This is an up-to-date Arch Linux install, running on an HP EliteBook 840 G8 (11th gen intel). I know Debian may have older components than arch, but this setup has been working for more than a year now.
IIRC, the most significant change was brought by systemd 251 which started supporting auto-unlocking LUKS with the TPM. Before that, on an older computer with the same general setup, hibernation worked well, too. I just needed to input the unlock password (which I was too lazy to do, so I just used my yubikey - see https://github.com/agherzan/yubikey-full-disk-encryption).

Encrypt data on server (Linux, LUKS) on Raspberry Pi
Full disk encryption is rarely as portable as simply encrypting the files you need. When I ran a “homemade” NAS, I had everything LUKS encrypted. I used a Yubikey to unlock the encrypted data.

Using a YubiKey to unlock LUKS - How to secure or encrypt /boot?
A few days ago I akquiriere a Yubikey and I'm currently trying to set up 2FA with the Yubikey and a password to unlock the LUKS container. Since I am running Arch I came across the yubikey-full-disk-encryption package and tested it in an Arch VM. So far it worked really well. The only issue I am having is that compared to my old setup I need to have /boot unencrypted because it seems GRUB itself cannot deal with the 2FA setup and ykfde if /boot is encrypted. Previously I had most of /boot inside the LUKS volume with only the /efi part unencrypted (this is used when telling grub where the efi-directory is - see the previous guide for the full details please) and the GRUB_ENABLE_CRYPTODISK=y option set in the GRUB config.

LUKS boot unlock fido2 issue
I don't know about the hanging, I use yubikey-full-disk-encryption which uses challenge-response (1FA or 2FA) which you can set up how many attempts to use the YubiKey before it falls back to the passphrase.

How safe is encryption?
https://github.com/cornelinux/yubikey-luks or https://github.com/agherzan/yubikey-full-disk-encryption with yubikey 5 will get you going. It is a bit expensive to get two keys (regular and backup), but these can be also used to secure most of the online accounts.

Encrypt Raspberry Pi?
For vulnerabilities: even if dropbear was vulnerable in some way, it’s running in a pre-boot initramfs with a restricted shell which can be locked down even further to prevent escalation. To add another layer of security, you can run Wireguard in initramfs and have dropbear configured to be accessible from only the vpn network: https://github.com/r-pufky/wireguard-initramfs

I self host on my desktop, but it likes to crash. Any advice on remotely resetting a frozen system?
Once you manage to reset the system, wireguard-initramfs should work if you need to SSH into it from outside the LAN, though the project is only currently supported on Debian. Within the LAN, dropbear in your initramfs should be enough.

How can I encrypt the whole disk on cloud hosts to prevent them from seeing my data in backups/snapshots?
There are other initramfs packages available that expand features such as wireguard capability: https://github.com/r-pufky/wireguard-initramfs
- Connect to remote encrypted SSH Client
- r-pufky/wireguard-initramfs - Enables wireguard networking during kernel boot, before encrypted partitions are mounted. Combined with dropbear this can enable FULLY ENCRYPTED remote booting without storing key material or exposing ports on the remote network.
