Horizon Forbidden West: What is the Eye of the Earth Base door code?

The Eye of the Earth major mission in Horizon Forbidden West begins as soon as you find a route up and slay the Grimhorn in The Dying Lands quest. You start by going deeper into the facility found in the Sacred Cave, but the security system discovers you almost instantly and puts the entire complex on lockdown. So you scout ahead for a means to get the lockdown lifted.

While looking for MINERVA, you can actually find the door to The Base's secret area. There's an open hatch to the right after you've pulled open a hatch and gone through it. The Base secret room is through that hatch, but even with the appropriate code, you can't open it yet. You must first speak with GAIA, ask her questions, gain the Established the Base trophy, then select your Subordinate Function quest before returning to the barred door.

The base door code for Eye of the Earth is 9626118. To unlock the door, interact with the console next to it and enter the code. There are five Datapoints on the opposite side of the door: Kelani Jenson, Fayna Leon, Emma Irving, David Makuto, and Ethan Reed all have logs.
