This is completely off-topic for the thread. If you have any questions please ask on Discord or start a separate thread. I’ll answer here anyway but in the future please do not go too off-topic on threads.
I think you are referring to BrightID. This is only used for the Faucet and it I find it hard to believe that it is unclear - thousands of people have gone through this process and there are resources on how to do it on both the Discord and on the forums.
The reason the faucet is locked behind BrightID is to make it sybil resistant so people can’t just create 1000s of new addresses and drain the faucet. If they could do this, the faucet would be pretty much worthless.
Generally documentation is under construction. Everyone caught us by surprise so we did not have anything in place. All of the growth in the 1hive community is fully organic, and we only intended to announce anything once documentation was in place. It ended up not working out that way. We have some swarms working on documentation (notably Fauna) and a bunch of community members who are trying to piece together documentation too. There are a lot of threads on the forum about these topics specifically, so if you would like to contribute to that we would highly appreciate it
