I currently use the hf side of my NExT for logging into various things as well as storage for some recovery keys, but Iām looking for the ability to change the serial number (or log in).
I believe the xM1 is what I want but I just wanted to verify that with you guys.
Thanks in advance for any insight you may have.
The xM1 or flexM1 will let you do that, but also I believe the flexMN.
Out of curiosity, why do you need to change the UID?
The ability to change the UID just increaseās their usability should a log in ever become compromised
So I assume you use the chipās UID as a direct login into your computer using a keyboard wedge, is that it?
In which case, a better solution would be to use a proper reader and a dedicated login program.
This is correct.
Would a dedicated login program render ability to change a UID useless?
Well sorry I should have made my answer more complete.
Changing the UID regularly in and of itself would add an extra layer of security (although āsecurityā in the context of a dumb RFID or NFC chip is all relative). Itās just like passwords really: if you cycle them regularly, they canāt be compromised long term. But itās not that necessary really.
What the login program brings is decoupling the keyboard input and the chip login itself. That is:
You keep your regular login, and you donāt have to use your chipās UID as a direct password - because quite frankly hex strings are not that easy to remember.
You donāt risk autotyping your password in a document, or worse, in a chat window or something if you approach your chip to the reader at the wrong moment
You are not at the mercy of the keyboard wedgeās exact output format if you ever change keyboard wedge brand / model and itās nor programmable
This here post by His Amalness is of interest. Look up the bit that talks about logging in with an ACR122. Assuming you use Windows of course.
This is the where the your password is stored in the hardware that scans your chips to verify?
I have mixed feelings of a separate piece of hardware having the password
Gives me the vibe of exterior lock boxāsā¦ just steal the box and get the key
Login programs are installed on your computer and should keep your chipās UID encrypted - just like they should keep your regular password encrypted also. A hypothetical external box should do the same.
I guess Iād be ok with a programā¦
Hardware I trust less, just because it could easily be taken?
Obviously youād notice and immediately change credentialsā¦ but seems like adding points of vulnerability
Hence two-factor authentication, if youāre that concerned. The hardware is one part, a password in your noggin is the second part. Authentication occurs when both are present. Think credit card and PIN number.
But consider that if you have a piece of hardware that reacts to one of your implants, itāll be basically useless without your implant - if itās properly designed and doesnāt store your implantās creds in plaintext on a SD card or something. So even with dump chips, in the case of implants, 2FA isnāt as much of a necessity.
Depression and anxiety are often linked, it sounds like you are able to āstare downā the anxiety side of the beast, which reeeealy deescalates the feels. Awesome skills!
Iām going to attempt to use this sentence to ask a sicky politely to back off during 2022 (or whenever normal illnesses come back into vogue)
So Iām currently (honestly, Iāve been feeling depressed and not felt like programming for a while now) working on the new version of my code. It can store a password on the chip. It can store a password on the reader, but XORed with the UID from the chip so only the right chip will decrypt it. Or can spit out the UID, or it can store the password in clear text.
This doesnāt stop you from putting your password into the wrong window, but it does mean that the actual password and the chip are decoupled.
My preference is for the password on the chip itself, and then the reader is just a reader. You only really need to worry about the security of your chip.
As for Covid/Christmas/Timeā¦ Life seems to have become one long monotonous cycle. The difference between Weekdays and the Weekend is whether I am working on Work stuff, or other stuff. Holidays have merged into weekends which are almost indistinguishable from weekdays.
āAnd they said to me, āCheer up, things could be worseā. So I cheered up, and sure enough, things got worse!ā
Or they just canāt afford to not get paid, at least until it becomes too much then they end up in the ER. Then they canāt afford the healthcare, andā¦
There is nothing wrong with the US that a real social safety net couldnāt fix.
Iām wonderingā¦ not that I want to make this forum into a potentially disasterous cluster fuckā¦ but Iām wondering if it might make any sense to start a private category to talk about depression? I have some thoughts and some experiences to share but I donāt know that itās a good idea to make this kind of conversation in a public forum.
So are ADHD, and delayed sleep phase (nocturnal), and other stuff
I often joke that Iāve got enough things that are linked with depression and anxiety, that if I was actually āfineāā¦ that would probably be quite concerning
Itās almost like the world shitting on people causes them to have a negative outlook or something 
Iām not sure about all that, In a nut shell itās like when I get a bad case of the āwhy bother-itusāā¦ I tell
Myself that in the end, almost nothing I ever do will matter, and I will eventually be forgotten to time
So if thatās the case, why not do something stupid and have a little fun along the way
A skill? Maybeā¦ I wouldnāt call it awesome or probably healthy though 
, but hey if it works
Anxiety=literally everything matters a lot
Depression=nothing matters
Adhd=I donāt know and canāt decide what matters
Eq brainā¦ letās just steer into ānothing mattersā and live in the moment and do stuff that doesnāt matter
I suspect we have enough people here with some form of mental health issues (depression and anxiety in my case) that it might be a good idea.
Somehow I didnāt see this comment,
I am not opposed, but I can also see it being a Pandoraās box alsoā¦ but why not
Optimistic Nihilism in a nutshell. Itās one of the philosophies that I try to live by.
Thatās right, I forgot it had a name
