Halo Waypoint Classified
From Halopedia, the Halo wiki
On Halo Waypoint was a section called Classified. A section that had a Forerunner based console that if the correct symbols were selected something would be unlocked to the user.
Summery
Terminals and other unlockables are recorded under Classified. There are five separate Data Sets: Alpha Halo Archive, Requiem Archive I, Requiem Archive II, Section 3 Archive, and Draetheus V Archive. These were found though numerous ways, most notably through the Section 3 ARG.
Codes
Alpha Halo Archive
The Alpha Halo Archive consists of the codes located at the end of the Halo: Combat Evolved Anniversary terminals that were spread out in every mission in the campaign. To enter a code, users had to find the terminals in order, then activate them. Every successfully entered code gives 7,000 cR, a background for the players stats in the defunct Halo Waypoint mobile app, and a video of the terminal on Halo Waypoint.
An eleventh terminal was unlocked by successfully entering all ten codes. This also awarded users with 30,000 cR, and a eleventh background for the players to use on for the players stats in the defunct Halo Waypoint mobile app.
Misc code - WAKEUPJOHN
Sometime after the translation for the symbols were discovered. Users started to attempt to brute force possible codes. This led to a user finding out that if someone entered the symbols to say "Wakeupjohn", a new video would be unlocked of a glitch, with subtitles that were related to the Anniversary Campaign Trailer. This was promptly locked and removed from the code pool. This suggesting it was not meant to be found.
Requiem Archive I
Requiem Archive I is unlocked by completing at least three Spartan Ops chapters and inputting three codes: "1UK3CVYJZM", "3VGRZJ1BS6" and "Q239SF2PGZ".

The code ("73P1SJ66O9"), described as the "Silentium coda", awards 20,000XP and unlocks the Rebirth video: a forty-minute narration by Greg Bear, describing the reintroduction phase from the perspective of Riser, which serves as an epilogue to the novel. A few days after the release of the Rebirth code, an eighth code was released.
