After solving a few puzzles (the Piano, Boiler, and Keypad, to be exact), you’ll enter a room with a computer that holds some crucial information, but it needs to be decoded. Hacking the computer in Black Ops 6 will take you a step further in your quest for some cash, allowing you to upgrade the safehouse with more amenities. Here’s how to easily crack the code.

The sheer number of numbers that appear when you try to decode the code can be a bit overwhelming, but once you know what to do, it's quite simple.
To hack the computer in Black Ops 6, you must match the numbers of the codeword (displayed at the top) with the characters highlighted in yellow at the bottom of the screen.
So if your code word at the top is 862915, look at the exact numbers in the code/character list at the bottom of the screen. In this case, 8 is B, 6 is U, 2 is N, and so on. Do this for all the words you want to decode and you should have a sentence at the end.
