+v3
+==
+
+mainly a manufacturing update.
+all parts are on one side.
+
+the schematic remains fully compatible with v2.
+
+changes:
+
+- remove fuse as the designed has been proved, and the glues should prevent shorts
+- put buttons on back side
+- use button mounting holes as test points
+
+v2
+==
+
+same USB type-A plug form factor.
+change MCU to STM32F042 since it provides read out protection, can recover 48 MHz clock from USB, and is easy to solder.
+
 v1
 ==

 smaller form factor.
-fits in USB A port.
+fits in USB type-A port.
 uses CH32V203 as it is smaller, cheaper, and requires less external parts (DP pull-up, crystal).

+issues:
+
+- USB pins are mirrored
+
 v0
 ==

 this is a large development board.
 it accepts the classical STM32F103 (which I'm more familiar with), and CH32V203 (cheaper).
 it has a proper debug port and buttons.
+
+issues:
+
+- USB pins are mirrored

+This USB dongle will help out if you have to enter your credentials frequently.
 Temporarily store the credential on it, and press a button for passkey to enter it for you.

 usage
 =====

 - passkey will appear as USB serial port and keyboard
- connect to it using a serial terminal (baud rate it not important)
+- connect to it using a serial terminal (baud rate is not important)
 - enter the credentials you often have to input
 - press on one button for passkey to input the username and password
- press on the other  button for passkey to input password
+- press on the other button for passkey to input password

-The credentials are saved in RAM and will clear as soon a power is removed.
-You can also clear the credentials by pressing on both buttons.
-The passkey will blink until credentials are saved.
+More details are provided in the [firmware](https://git.cuvoodoo.info/kingkevin/passkey_fw/src/branch/passkey).

-Configuration available in the terminal:
+hardware
+========

- which button is for which action
- the keyboard layout used
- global timeout to clear the credentials
- last usage timeout to clear the credentials
+The passkey is a USB dongle that fits within a USB type-A port.
+Only the two buttons stick out to you can press on them.
+An LED indicates if credentials are stored in the dongle.
+Cover the back of the PCB assembly with hot glue so it fits well the USB port and does not create shorts.
+
+mode of operation
+=================
+
+The core of the device is a micro-controller that supports native USB.
+I will act as serial port, to input the credentials, and HID keyboard, to paste back the credentials.
+
+After several trials, I chose the STM32F042F6P for the following reasons:
+
+- small enough to fit in USB port
+- TSSOP package easy to hand solder
+- does not need an external crystal, as it can recover the 48 MHz clock from the USB communication, saving board space
+- has embedded balancing and pull-up USB resistors, saving board space
+- is readily available and cheap, hoping the next chip shortage will affect it less
+- has little embedded flash (32 kB), but enough to run tinyUSB (not libopencm3 though)
+- provides readout protection, to lock the flash and disable the debug interface
+- requires little power, to use a small LDO, saving board space
+
+The board has test points on the back for SWD (labeled C for SWCLK and D for SWDIO), and UART debug (labeled G for ground and T for RX).
+
+A fuse is added to the board, just to prevent shorts when the dongle is plugged in but the glue is not applied correctly on the back of the board.
+
+Physical tactile switches are used instead of capacitive touch to avoid accidental credential pasting.
+
+A hole between the two buttons allows to put it on a string.
+This makes removing the dongle from the port more easy.
+This way you can also put it on your key-ring, so it is less likely you forget the dongle when leaving the computer unattended.
+
+The MCU and readout protection have no security certification.
+They could probably by bypassed using fault injection.
+This could allow an attacker to install malicious firmware, saving the credentials in non-volatile memory for later retrieval.
+Thus, it you notice any tampering of the device such as different glue pattern, just toss the device away.
+The under $2 cost for this device makes it not worth the risk.
+If you don't trust the source where you got the device from, since the hardware and firmware are open-source, just build the device yourself.
