All Authentication Card Key Locations in Honkai: Star Rail

In Honkai: Star Rail there may be times where you must find multiple parts to complete a Quest and opening the Authentication Room inside the Herta Space Station is no different. Here players are given clues to locate the required Access Cards to unlock the Triple Locked Room where Treasure lies in wait for you to nab at your leisure. As every Access Card requires different gameplay to obtain them, it can get confusing knowing where to go or what to do in order to find the Access Card. But Gamer Journalist has you covered, this is our guide on where to find every Authentication Card Key in Honkai: Star Rail.

Where to Find All Cards to Open Authentication Room in Honkai: Star Rail

Opening the Authentication Room can be tricky if you do not know where to look. You will be trapsing around the Herta Space Station, likely searching in every room for a Chest with the Access Card inside. Not only do you need to find the Access Cards but, there are a total of 3 to find within the Space Station itself. Whilst some require a bit of platforming/puzzle solving, others will simply require a bit of communication with your fellow Space adventurers and some are not happy to see you. Yes, there are enemies on board the Station but they hide behind locked doors and it is where you must search when looking for the 3 Access Cards to open the Authentication Room.

The main areas you need to search are the Base Zone, Storage Zone and Master Control Zone. Of course, whilst we are pointing you into a general direction, we will now explain as best as we can on exactly where each Access Card can be located and what you have to do to obtain them.

Authentication Card Locations

• Base Zone – Located in the room at the north-east side of the Map. This is on the room on the right at the very northern peak of the Map. In this room however, is an single enemy that you must fight in order to get the dropped item, ‘Access Authentication’. Behind the enemy is a Chest that you can now open after taking the enemy out in the battle.
• Storage Zone – On the far west side of this Zone is an area in which you must complete the platforming puzzle to get to the other side of the room. By getting to this side, you will find the ‘Thousand Stars Access Authentication’ item on the right-hand side of the doorway. Simply stand against the doorway, facing the right arch and interact on the side of the platforming puzzle. There is a glowing indicator for an item here which is the second Card needed for the door.
• Master Control Zone – The final Access Card is easily obtained inside this Zone. All you need to do is walk slightly north from the Zone entrance and stay on the path until you reach a fork in the road which goes left, right or forward. Directly in front and on your left, a Man with an Afro is standing there, just after the fork in the road. Speak with him until you clear every dialogue option. In the end, he will give you the final ‘Corporate Access Authentication’.

With all 3 Access Cards obtained all you need to do now is head back to the Triple Authentication Room to use the Cards to unlock the door via the Controller outside the room. When the door unlocks, there are two enemies in the room that you must defeat in order to open the Chest and obtain the Treasure inside at the back of the room (behind the desk).
