How to Open the Triple Authentication Room in Honkai: Star Rail

Before entering the Triple Authentication room, you’ll have to get your hands on three access keycards to unlock the door and complete the Road to Revival quest line. Be prepared to fight some enemies and explore the entirety of the space station!

With that said, let’s talk about how to get each keycard!

1. Corporate Access Authentication

Our first stop for this adventure is the Master Control Zone, where you’ll find various NPCs. Most importantly, you’ll spot a shop owner just northwest of the Central Passage Space Anchor alongside another character simply named “Man with Afro”. Speak to him five times to get your first keycard, the Corporate Access Authentication card!

If you want to get there extra quick, Honkai: Star Rail allows you to fast travel all around the map, including to the exact spot where you’ll find the man with the afro.

2. Thousand Stars Access Authentication

Our next stop for this multi-part series is the Storage Zone! Fast travel or run to the “Outside the Control Center (First Floor)” Space Anchor on the area’s west side before entering the nearby room. Here, you’ll find various platforms, enemies and colored bridges, which you must activate and deactivate to reach the other side. Below is a step-by-step guide to navigating this bridge room and obtaining the Thousand Stars Access Authentication card:

1. Enter the room, descend the left ramp and defeat the nearby enemy.
2. Interact with the bridge console to deactivate the orange bridges and light up the blue ones. Cross the newly-created blue bridge.
3. Go down the ramps and interact with the second bridge console to activate a white bridge.
4. Continue up the ramps and search behind the white crates to find a hidden bridge console. Turn it on to reveal the orange bridges again.
5. Head up the ramp and cross the orange bridge, followed by the white bridge. Turn on the nearby bridge console to reactivate the blue bridges.
6. Cross the white bridge and run past the new blue bridge before ascending the final ramp and collecting the Thousand Stars Access Authentication card.

From this point, the authentication card appears as a yellow sparkle on the ground, which you can interact with to obtain the keycard. You can also open a treasure chest in the room for extra goodies.

3. Blank Access Authentication

The final stop for opening the Triple Authentication room is the Base Zone. Head to the Monitoring Room at the area’s northernmost part and defeat the enemy guarding the chest. It’s a challenge, so make sure you level up your characters and have them fully healed! Eliminate the enemy to automatically get the keycard, allowing you to return to the Triple Authentication room just south of this one.

If you’re really feeling confident, you can even use HSR’s auto battling feature to fight them.

After defeating the blank keycard miniboss, head south and interact with the door console to open the Triple Authentication room. Be prepared to fight more enemies once you enter! Once you defeat them, you can open the treasure chest and get your reward!
