Yup! It is possible and there is actually an app that does this: https://github.com/GetIn-id/

It is what I currently use to authenticate with SN but it got me curious and I wanted to try creating my own little tool to do the same thing in nodejs.

GetIn is cool because it generates a seed phrase just like you would use to store Bitcoin and then you can generate profiles off that phrase to log into individual sites with. I want to build a similar app, but I have a different vision in mind than they do on the overall direction I want to take the app.

This link contains a lot of detail on implementation and links to the specific LUDS #98600

The biggest challenge so far is the documentation. If you get stuck and need to search for examples, the examples are most likely outdated because the libraries used have since changed some things around or gotten rid of functions entirely. So a good portion of my journey has been re working all these steps in isolation because it wasn't often clear that the documentation or example is outdated.

It is also frustrating that documentation has no consistency. Why does LUDS 05 show an example in Scala but LUDS 04 is in python?

It is just growing pains of both young documentation (most of it did not exist more than 2 years ago) and outdated documentation due to libraries updating. Positive changes overall but is challenging to navigate.

Thanks for helping with visibility. This is a burner account. I have returned the sats.
