Creating a Second Factor Authentication Token
Today I worked on the blog, helped rearrange the office, opened up all our beautiful PCBs (https://blog.redkeyu2f.com/2018/07/05/u2f-token-building-the-pcbs-arrive/), and started learning about reflow ovens. Now that all our parts are here, we have to learn how to properly use our toaster oven to solder our boards. Apparently there’s quite a bit of technique to this- good …
Today I sat and learned a whole bunch from my employers. We talked about different jobs, how other employers act, money, and a whole lot of other stuff. Then, I set off to try and clear the fog that learning about electronic components had put on my brain. Just watching videos wasn’t working, so luckily …
We found all the parts needed to build a simple U2F security token thanks to Github. Here’s the link: https://github.com/conorpp/u2f-zero/wiki/Parts-List Basically there are 8 components per token. All should be surface mount parts. Here’s what you need: PART MANUFACTURER PART NUMBER PRICE PER WHERE TO FIND Microcontroller EFM8UB11F16G-C-QSOP24 $1.38 https://www.digikey.com/ Secure Element (Authentication chip) ATECC508A-SSHDA-B $0.75 …
Learning to desolder takes a lot of time. The first time I tried, it took me almost 30 minutes just to remove 1 component! There’s a lot of technique involved, so every night I try to practice on old circuit boards. When I think I have this under control, I’ll move on to soldering small …
I’ve been working on my co-op for a couple weeks, but this is my first daily update. All my parts are ordered, so right now I’m just trying to learn a lot to prepare for the more hands-on portion of my co-op. Today I studied soldering/desoldering techniques- practicing for hours on old circuit boards, …
Once the basics of the project were all laid out, it was time to figure out a schedule. Not only do I have a certain number of co-op hours I must hit, I also have a small period of time to do it in. I just finished summer school this week, and all my hours …
After finding a co-op, the next thing is to figure out what you’ll be working on for the next 3 months. My project? Building my own second factor authentication token. The need to protect your online accounts is an increasingly important thing. Companies often have security breaches, and passwords (no matter the length) are easily …
