But Why??

There are a few reasons why I made this device, mainly to lose dependence of my phone. But not just, What if your phone breaks, bricks, or something else? I rather have lots of devices that don't depend on eachother rather than a all in one for that reason, plus most "universal" stuff performs worse than a specific device for that single function. As of right now, I'd say it's almost complete (enough to daily drive), possibly a few more hardware security features, maybe UI polishing, fixing any bugs i haven't found yet and should be perfect. The cost is ~£6 excluding 3D printing.

Hardware is:

• Nice!Nano: AliExpress Link
• DS3231 RTC: AliExpress Link
• 0.96Inch Display: AliExpress Link
• 6*6 Silicone Switch: AliExpress Link
• 3D model

Usage

Use the NiceTOTP-Configurator (Firmware update doesnt work rn*)

or you can use serial commands:

• setunixtime example: setunixtime 1751925355
• add <username> <base32secret> example: add test JBSWY3DPEHPK3PXP (Compare)
• list
• del <GetTheIDFromListCommand> example: del 1
• factoryreset (Power cycle after)

Installation

• Build and flash the project with platformio (Make sure you add nicenano support here)
• Or Drag and drop the .UF2 onto the nicenano drive when doubble clicking reset (short rst pin with usbc sheild tapping twice quickly)

More Info

• In 2 months the RTC drifted 8s forward.
• It still shows the right code tho, but that means the last 8 Seconds are invalid. I will need to see whats up with the RTC
• At month 6 it looked like 50%, battery life seems like a year then.. charging it now so yeah.
• Make sure not to let it discharge as it will go in a soft brick, to unbrick you just press rst (mentioning it if you glued shut the case like i did when i was done with hardware but not firmware.)
• If you want protection over phisical attacks, you want to use something like a st-link and run approtect.py which blocks reading firmware, but there will still be other ways to get keys as a hardware hacker, so just noting!!!
