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.

Encrypted hard drive asking for password every time (lemy.lol)

I recently switched to Linux (Zorin OS) and I selected "use ZFS and encrypt" during installation. Now before I can log in it asks me "please unlock disk keystore-rpool" and I have to type in the encryption password it before I'm able to get to the login screen.

Is there a way to do this automatically like with Windows or MacOS? Zorin has biometric login which is nice but this defeats the purpose especially because the encryption password is long and tedious to type in.

Also might TPM have anything to do with this?

EDIT: Based on the responses I have to assume some of you guys live in windowless underground bunkers sealed off with concrete because door locks "aren't secure against battering rams". Normal people don't need perfect encryption they just want to add an extra hurdle or two for the crackhead who steals the PC. I assumed Linux had a system similar to what Windows or MacOS has been doing for a decade but I am apparently wrong.

Bypassing login is not difficult on a lot of OS.

Yeah, but a lot of those things will trip the TPM module, so you will get a different decryption key if you for example try to use the single kernel parameter to boot into a root shell. And different decryption key means no access to the data.

At least on Windows that requires booting the PC from some other media, and that wouldn't work with the drive encrypted because you have no access to the files you need to modify.

Is it similar with Linux, or do you mean you can actually bypass login from the OS that's already booted up??

It is similar in Linux. Vulnerabilities, bugs, or enough time will get through on any OS so people have to decide on their personal level of paranoia. A lot of people have very little idea how a TPM or sealing key material works.
