Encrypt your Linux with LUKS, like seriously. (lemmy.ml)

This makes a world of difference. I know many people may know of it but may not actually do it. It Protects your files in case your computer is ever stolen and prevents alphabet agencies from just brute forcing into your Laptop or whatever.

I found that Limine (bootloader) has the fastest decryption when paired with LUKS at least for my laptop.

If your computer isn't encrypted I could make a live USB of a distro, plug it into your computer, boot, and view your files on your hard drive. Completely bypassing your Login manager. If your computer is encrypted I could not. Use a strong password and different from your login

Benefits of Using LUKS with GRUB Enhanced Security

Data Protection: LUKS (Linux Unified Key Setup) encrypts disk partitions, ensuring that data remains secure even if the physical device is stolen.
Full Disk Encryption: It can encrypt the entire disk, including sensitive files and swap space, preventing unauthorized access to confidential information.

Compatibility with GRUB

Unlocking from Bootloader: GRUB can unlock LUKS-encrypted partitions using the cryptomount command, allowing the system to boot securely without exposing sensitive data.
Support for LVM: When combined with Logical Volume Management (LVM), LUKS allows for flexible partition management while maintaining encryption.

That's what TPM is supposed to solve. As long as nothing changes on the PC you don't have to input a decryption password and access is protected by your usual user password.

On one of my computers I have LUKS and requires me to type in two passwords. Not sure if it has TPM

Could be a misconfiguration. Can happen when you have more than one partition that is encrypted. Grub would decrypt only root and fail to pass through the passphrase to decrypt the others. Can be fixed by putting a decryption key somewhere on the root partition and adding that to the other partitions.

That's definitely not how it should be, unless you have two different passphrases.
