Hi Siddhi, Nice to know you are interested in participating in the GSoC 2026.
There is also another user interested in adding support to multi-user on NuttX. I suggest all candidates interested to work on some project to open an issue in the Github to list it and make it easy to track: https://github.com/apache/nuttx/issues?q=state%3Aopen%20label%3A%22gsoc2026%22 The steps you listed here are mostly right, please note that NuttX already have login authentication in place, you can test it enabling in sim:nsh these options: CONFIG_NSH_LOGIN=y CONFIG_NSH_CONSOLE_LOGIN=y CONFIG_NSH_LOGIN_FIXED=y Also keep in mind that we have 10 projects participating in the GSoC, so projects like porting NanoX to NuttX don't have candidates yet.
