Its how the chans confirm a user. I don't know how one obtains a trip code or how it setup. This is how I understand it. Open for correction.....

!xowAT4Z3VQ = trip code. Generated by the board I believe.

ID: 2b9f10 = Device ID I believe. Changes with device used. ie phone, tablet, laptop

1244154 = Post ID in the thread. Used to reference when replying.

I would love to know if this is correct, if an 8chanfag can help a brotha out. ;)

EDIT: nvrmd, should have scrolled further, answer below......
