However, unlocking the vault isn't as simple as entering a regular password. You'll need to access Miranda's computer, locate the vault reset instructions, and discover her date of birth.

This Rivage Miranda's Vault Puzzle Guide explains how to find the necessary clues, reset the vault password, and unlock Level 1 access.

How to Solve Miranda's Vault Puzzle in Rivage

To open Miranda's Vault, you must first discover the password for her computer and locate the reset instructions hidden in the nearby hallway.

The puzzle involves three important clues:

Computer Password: Found by examining a book on Miranda's desk.
Vault Reset Instructions: Located inside a container in the hallway.
Miranda's Date of Birth: Revealed in an email on her computer.

Once you've collected these clues, you can return to the vault and unlock it.

Step 1: Find Miranda's Computer Password

Start by approaching the computer on the desk inside Miranda's quarters.

Interact with the computer and select the Forgot Password option. You'll receive a password hint that reads "My Bestseller."

Rivage Computer Password

To solve this clue, examine the nearby book titled Stardust.

Enter the following password:

Computer Password: Stardust

After successfully logging in, open Miranda's emails using the paper plane icon.

Look for an email from Optima Vault concerning a vault reset. This message contains Miranda's date of birth, which you'll need to unlock the vault.

Make sure to record the date using K9 or write it down before leaving the computer.

Step 2: Find the Vault Reset Instructions

Once you've obtained Miranda's date of birth, leave her quarters and enter the hallway.

Near the station's floor map, you'll find a container that holds the vault reset instructions.

To open the container:

Approach the container beside the hallway map.
Release the latches securing its front.
Pull the upper handles to open it.
Examine the instruction leaflet inside.

The leaflet explains how to reset the vault's existing password using a special command.

You can now return to Miranda's quarters and interact with the Optima Vault near the doorway.

Step 3: Enter the Vault Reset Code

Interact with the vault's keypad and enter the following reset command:

Vault Reset Code: /000/

Press OK to confirm the command.

The vault will switch to a date-entry screen, requiring Miranda's date of birth.

Rivage Mirandas Date of Birth

Enter the date you discovered in the Optima Vault email, following the displayed DD/MM/YYYY format.

Important: Miranda's birth date can vary between playthroughs. Avoid copying a date from another player's game, as it might not work in yours.

Once the correct date has been entered, the vault's opening mechanism will become active.

Interact with the illuminated handle and move it to open the vault.

What Is Inside Miranda's Vault?

After opening the vault, you'll gain access to several compartments containing documents and Miranda's identification card.

The most important reward is Miranda's Level 1 Access Card, which allows you to enter previously restricted areas of the station.

To activate the card:

Pick up Miranda's identification card.
Rotate it to examine the reverse side.
Locate the barcode printed on the back.
Scan the barcode using the K9 System.

Scanning the card permanently registers Level 1 access, allowing you to retain the authorization through future time loops.

Once you've completed this step, leave Miranda's quarters and head toward the Kitchen door in the hallway.

You can now unlock the door and continue exploring A.R.E.S.

Final Thoughts

Miranda's Vault Puzzle introduces several important mechanics in Rivage, including environmental clues, password recovery, and access-card scanning.

The key to solving it is finding the computer password, reading the Optima Vault email, and entering the correct reset command before supplying Miranda's date of birth.

Remember to scan the identification card after opening the vault, as Level 1 access is essential for progressing into the Kitchen and exploring additional sections of the station.
