    I saw the lack of arm and facepalmed but I was half asleep poo posting so got over it :p (fixed now!)

    I’ve been using this device for ~5 years now, so my memory is a little hazy on it, but I’m pretty sure for the particular device I prefer (which is to say, I have nfc what the setup is for other vendors, which could be greatly superior) the AES-256 key used for encryption isn’t generated until you setup your first card.


  • How would any company, regardless of geography have the secret I generated? This is a stand alone hardware device. They seller is not involved at all once I’ve received my package.

    Could a sophisticated/well resourced actor clone the smart card they stole or you lost? Sure, brute force attacks are brute force attacks. At least you’d know your device and card are stolen. Now you’re in a race to reset your passwords before they finish making 500 clones of the smart card they stole.

    Hypothetically I could blackmail someone at LastPass and have a backdoor is installed for me.

    Someone could bust down my door while I have it connected and unlocked and just login to all my things. ¯\_(ツ)_/¯


  • That will vary from vendor to vendor. In the case of the one I like there are a few relevant things.

    The password db is stored encrypted on the device. Accessing the passwords requires all of:

    • the device
    • a smartcard with a particular secret on it
    • the 4 digit hex pin to unlock the secret on said smartcard, which is what is used to decrypt the db

    Three PIN failures and the smart card is invalidated.

    That sort of covers “stolen” and “lost + recovered by a baddie”. Your bad actor would need to have their hands on both physical pieces and guessed the 4 digit hex code in 3 tries.

    As far as a user recovering from a lost or failed device or smart card goes, you can export the encrypted version of the db for backups, which I do to a thumb drive I keep in my document safe. I do the same with a backup smart card. So that and a backup device or purchasing a new one if yours fails or is lost/stolen.

    In the super “just in case” move, I also keep a keepassdb on said thumb drive. In case my device fails and it’s just not possible to get a new one. Kind of like keeping two cloud providers in case LastPass goes bankrupt or something.

    So many folks talking about which software they use, and how they sync it between devices etc.

    You all know there are hardware password keepers right? They present to your devices as a usb and/or bluetooth keyboard and just type out the user/password that you select. They have browser plugins to ease the experience. Now your password is not even stored on the device you’re using to perform your login and it will work on any modern device even without internet access.

    Oh and no subscription fee to cover the costs of cloud infrastructure.



  • You’re absolutely right. For what it’s worth, it’s just the first part that’s important.

    When you pick up a new concept from a “resource” such as a tutorial, take a minute to explore the concept and understand the semantics of what you’re doing. In the name of illustrating a concept tutorials can often be misleading in subtle ways.

    An explanation of my “useless use of cat” example:

    The command line has a concept called “piping”. This lets one command send output to a second command. It’s very handy. There is usually also a “cat” command, which will read a file and send the contents where you tell it. This is often your screen, or through a “pipe” to a second command. There is also a “grep” command that lets you search data for certain words.

    Many “linux newbie” tutorials combine these tools to show how “piping” lets you send data from one command to another. “cat” some text file, then “pipe” the output to “grep” to search for your words. It usually looks something like cat ./my_address_book.txt | grep Giles to find lines in “./my_address_book.txt” that contain the word “Giles”. The thing is that “grep” can take a file name as an argument. You can just do grep Giles ./my_address_book.txt, and cat is for concatenating files into one. If you want to simply read a file there are more appropriate tools such as “less”. This by the way is the “useless use of cat”

    When you’re a newbie though, it may be the first time you’re seeing either “grep” or “cat”. The tutorial is just trying to show you “pipes”. Along the way you’re picking up these “bad habits”. I’ve met professional sysadmins who didn’t know grep took a filename as an argument. It was always “cat blah | grep my_search”. I will see people type “cat /some/file | less” instead of “less /some/file”. It shows a lack of understanding of what these tools actually do, and IMO it just comes down to regurgitating tutorial actions without bothering to understand the semantics of what you’re being shown.


  • Don’t follow tutorials, understand them. I’m so tired of seeing useless uses of cat because some asshole writing a tutorial 20 years ago decided to illustrate how pipes work with a good ol cat file | grep string as if grep didn’t take a file name as an argument.

    The more time I spend being mad about this the more I notice people using horrible practices in tutorials because they’re too lazy to setup a legit use case.

    A new user sees this and thinks this is how grep works.

    Loops are another common one. People going around not knowing you can pass a glob to a shell for loop. Because the tutorial they read was lazily written and they didn’t bother to understand the bits of what they were being shown, only how to reproduce/mangle the command until they manage to get close enough to what they want out of it.


  • Same here. Reference, particularly sheet music and cooking recipes work fine for me digitally.

    I can sit at the computer and read social/news media for hours with no problem, but the way ebooks are displayed tires my eyes very quickly for some reason.

    While I don’t have this issue with the e-ink/e-paper stuff, I’ve never owned one. I also appreciate that physical books are often much harder to damage and will work without electricity.



  • Bouncing around between two for the most part.

    I’m mostly playing Guild Wars 2, enjoying saving the world from demonic invasion in what has so far been a pretty great expansion IMO and I am a bit of a hoor for some of the new cosmetics.

    When I need a break from the rough grind, I jump into a super duper rough grind by firing up ol Leaf Blower Revolution. Idle game my ass, I’m clicking more than 5 cookie clicker players combined! There are still leaves everywhere!
