How do you open the triple authentication door in Herta Space Station Base Zone in Honkai: Star Rail?Most puzzles you encounter inHonkai: Star Railare part of a larger mission, and even if you need to think about their solutions a little, they will at least be fairly well-signposted. But the locked door in the Base Zone of Herta Space Station is an anomaly: you’ll only know about it once you try (and fail) to enter it, and the clues as to how to open it aren’t tracked in your mission checklist, making it easy to get lost and confused.

Luckily, we’ve worked out how to get through the triple authentication door and claim the goodies behind it. Read on for details of every step to getting that pesky door open and information on what you can expect to find within.

Where is the triple authentication door in Honkai: Star Rail?

The locked triple authentication door inHonkai: Star Railis located in the Base Zone of Herta Space Station. It can be seen on the map on the right-hand fork of the main corridor in the northern part of the area. You will unlock this area as you progress through the “Road to Revival” sidequest, which activates after you receive a text message from Arlan.

Stelle stands in front of a plinth-mounted door control console in a corridor of Herta Space Station in Honkai: Star Rail. An error message informs her that the door is locked and prepares to give her a hint as to how to unlock it.

Note that, despite their nominal ordering, you can retrieve the three access cards in any order, and indeed do not need to have viewed these hints or interacted with the door control in order to do so.

How to obtain Tier-1 Certification

To get the first special access card, you simply need to talk to an NPC called Man With Luscious Hair five times. You can find him in the Master Control Zone, standing in the central corridor just north of Wen Shiqi the merchant. (Note that he actually uses the same model as Wen Shiqi, which had me confusedly trying to chat up the wrong character for literal days.)

You simply need to have five conversations with the Man With Luscious Hair, which you can run through back-to-back or leave for as long as you want. He’ll keep a helpful tally of how many times you’ve spoken as part of his dialogue, which goes from silly to devastatingly tragic as his story unfolds.

Return to the door and interact with its controller once again to plug in the necessary items. You’ll receive a few small rewards for completing the late-blooming “Emptiness of Locus Silentii” sidequest, but more importantly, you can now access the Base Zone Monitoring Room.

Insidethe room you’ll find a couple of Voidrangers from the Antimatter Legion — whom you can defeat in battle to receive Formidable Foe rewards — and a Precious Treasure chest containing a 4-star Light Cone (I got “The Seriousness of Breakfast” for Erudition, but it may be randomised) along with a few more standard treasure rewards.
