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.

It's quite possible to set up LUKS with a USB key instead.

What if they get your laptop and your USB key then

Obviously that would be a total compromise. However this all depends on your threat model and how you usually use your laptop, and if someone were to steal it, would they also mug you for your flashdrive?

In my case, I just type the passphrase I have into the laptop, although my homelab server uses a USB so that it can unattended reboot, and I can put the USB in a secure location if it doesn't need to reboot unattended.

Otherwise, in my case I usually go out with a laptop that if stolen, is only worth about $150 AUD so not a big financial hit. While I have LUKS as a passphrase, I'm not likely to be a target of any individual or entity that, if they really wanted my data, would also mug me for a USB key, so I could live with either.
