What are Security Codes in Anime Vanguards?

In Anime Vanguards, the Happy Factory Act 1 is not just about placing towers and defending waves; it introduces a puzzle element known as Security Terminals. These terminals are scattered throughout the map, often hidden in side paths or near boss arenas. To progress to 100% completion or to grab the hidden loot chests that drop game-changing items (like Mythic Unit Shards or massive amounts of Gold), you must input specific numerical sequences.

Unlike the generic “Redeem Codes” you enter in the game’s shop for freebies, these Security Codes are part of the level design. They function like keys to locked doors. If you miss them, you are essentially leaving free resources on the table—resources that could help you summon stronger units for later acts like Infinite Castle or Tokyo.

All Happy Factory Act 1 Security Codes (March 2026)

Based on our research across top guides including Roonby and the official Anime Vanguards Wiki, we have compiled the complete list of active security codes for Act 1.

Code #1: The Entrance Gate Terminal

The first terminal is located right at the spawn area, behind a stack of crates to the left. Many players miss this because they are too focused on setting up their initial defense line immediately.

Code: 7269
Rewards: 500 Gold & Common Essence
How to find it (In-Game Clue): The code is actually scribbled on a whiteboard in the background of the cutscene that plays when you first load the map.

Code #2: The Catwalk Override

Midway through Act 1, around Wave 5, enemies start spawning from the upper catwalks. To access the vantage point or simply unlock the supply drop on the ground floor, you need this code.

Code: 4920
Rewards: 1,000 Gold & Rare Essence
How to find it (In-Game Clue): Look for a flickering neon sign on the wall opposite the terminal. The flickering lights blink in a sequence: 4 blinks, pause, 9 blinks, pause, 2 blinks, pause, 0 blinks.

Code #3: The Secret Vault

This is the big one. Located in the basement area that unlocks only after defeating the Wave 7 mini-boss, this vault requires a 4-digit code to open. It is guarded by elite enemies, so be prepared.

Code: 8531
Rewards: 2,000 Gold, Mythic Unit Shard, and the “Factory Pro” Badge.
How to find it (In-Game Clue): There is a note dropped by the mini-boss. If you zoom in on the item description in your inventory, it reads: “Reverse the order of the valves: 1, 3, 5, 8.”

Code #4: The Developer Easter Egg

Not strictly necessary for gameplay completion, but essential for collectors.

Code: 1234
Rewards: A secret “Bob” Unit and a funny audio track.
Location: Inside the ventilation shaft near the final arena.

Step-by-Step Guide to Redeeming Security Codes

Using these codes isn’t just about typing numbers; you have to reach the terminals alive. Here is the best method to ensure you get that loot without wiping your team.

1. Preparation is Key

Before starting Happy Factory Act 1, ensure you have at least one unit that can handle “Crowd Control.” The Happy Factory map is narrow, and while you are busy running to a terminal, enemies might slip past your defenses.

Recommended Unit: Speed Tier units like Naruto (Six Paths) or similar meta units available in 2026 that offer high area-of-effect damage.

2. Timing Your Run

Do not try to input codes during a wave (unless it is a wave clear period).

Best Time: Immediately after a wave clears, when the countdown timer for the next wave is above 10 seconds.
Team Strategy: If you are playing multiplayer, communicate! Tell your teammate: “I’m grabbing the vault code, cover the left lane.”

3. Interaction Sequence

Once you reach the terminal:

Walk up to the keypad and press the interaction button (E on PC, Tap on Mobile).
A UI window will pop up with four empty slots.
Type the code using your keyboard or the on-screen numpad.
Press “Enter”.
If correct, the door will open, or a chest will spawn instantly.

4. Loot Collection

Remember, the loot does not go directly to your inventory sometimes; it spawns as a physical crate. You must walk over it to collect the Gold and Essence.

Advanced Strategies for Happy Factory Act 1

Now that you have the codes, let’s talk about how to actually beat Happy Factory Act 1 efficiently. Security codes are just one part of the equation.

Unit Composition for Act 1

The Happy Factory is filled with robotic and armored enemies. Pure damage dealers might struggle against the high HP of the boss units.

Farmers: You need economy. Place a gold generator unit (like the Greedy Merchant archetype) near the start.
DPS (Damage Per Second): AoE (Area of Effect) units are king here because enemies often clump up in the factory hallways.
Support: Don’t forget a unit that can slow enemies. The Security Code terminals are often far from the main path; if an enemy speeds past you while you are typing a code, a slowdown unit can give you those precious few seconds to get back in position.

Navigation Shortcuts

Knowing the codes gives you access to shortcuts.

The Catwalk: Inputting code 4920 opens the maintenance hatch on the catwalk. This allows you to place a Sniper unit directly above the enemy spawn point. This is a “Pro Strategy” that allows for maximum damage output before enemies even reach your main line.

Common Mistakes to Avoid In 2026

I see so many players make these simple errors. Don’t be one of them!

Typing while fighting: Trying to input 8531 while a boss is shooting at you is a recipe for disaster. Always clear the immediate area first.
Forgetting to check codes: Some codes change with monthly updates. The 4920 code was updated in January 2026 (it used to be 4919), so always bookmark this guide to check for changes.
Ignoring the Loot: I’ve seen players open the vault and then run off to the next wave without picking up the Unit Shard. That Mythic Shard could be the difference between getting your favorite character or not!

Community Insights and Developer Updates

We dug through the Official Anime Vanguards Discord and Twitter/X to bring you insights that other guides might miss.

Why Do Codes Exist?

According to a recent dev log, the developers added Security Codes to encourage exploration. They stated: “We wanted players to feel like they are actually breaking into the factory, not just walking through a hallway.” This is why the codes are tied to environmental clues (like the blinking lights or whiteboard notes) rather than just given to you.

Are Codes Random?

A common question on Reddit is: “Are the codes different for everyone?”
The answer is NO. For the public servers of Anime Vanguards Happy Factory Act 1, the security codes are static. Everyone gets the same code in the same location. This allows guides like this one to exist!
However, in “Private Servers” or during “Hardcore Mode,” there is a small chance the codes might be randomized or require solving a math problem generated by the game. For standard play, stick to the codes listed in our table above.

Recent Patch Notes (March 2026)

The latest patch addressed a bug where the Vault Code (8531) would not register the last digit ‘1’. This has been fixed as of the latest hotfix. If you are still experiencing issues, try re-entering the server.

FAQ’s

How often do the security codes change in Happy Factory Act 1?

Security codes in Act 1 typically do not change unless there is a major game update or patch that alters the map layout. The codes listed here (7269, 4920, 8531) have been stable since the 2026 New Year update. However, developers often rotate codes for seasonal events, so check back monthly!

What happens if I input the wrong code?

Nothing bad happens! You won’t take damage or get kicked out. You simply have to re-enter the correct sequence. There is no penalty for guessing, so feel free to try if you think you found a clue.

Can I do Happy Factory Act 1 solo?

Yes, absolutely. In fact, it is often easier to find the codes solo because you don’t have to coordinate with teammates. Just ensure your unit loadout is strong enough to handle the waves alone. A meta DPS unit is essential for solo runs.

Do the codes work on Mobile and PC?

Yes, the security codes are universal. Whether you are playing Anime Vanguards on iOS, Android, or PC via Roblox, the codes remain exactly the same.

I input the code but the door didn’t open. Why?

This is usually a sync issue. Try walking slightly away from the terminal and walking back, then interact again. Also, ensure you are entering the numbers quickly; the terminal interface sometimes times out if you idle for too long. If that fails, the code might have been patched in an update—refer to the top of this article for the latest verified codes.

Conclusion

The Happy Factory Act 1 in Anime Vanguards is a brilliant blend of tower defense action and puzzle-solving.
