Two-Factor Authentication Mission Objectives- Explained

Before jumping into a mission it is always better to check the tasks you need to complete. This season, the Zombies mode has brought missions that can’t let the players randomly complete tasks. If you want to complete them, you must be prepared with weapons and armor beforehand. So, if you are trying to dive into the Two-Factor Authentication mission, check out the below objectives:

Complete a Defend Ground Station Contract
Kill 20 Mercenaries during the contract
Maintain the computer’s health above 60%
Exfil with the Death Perception Recipe

If you have noticed the objectives, you probably find them easy enough to complete. That’s even true. As Act 3 missions, these objectives are easy to complete. But still, newcomers may require some help completing them. So, in the next section of the guide, we will tell you how to complete the mission faster.

Easy Steps to Complete the Two-Factor Authentication Mission in Modern Warfare 3 Zombies

Generally, each tier of an act has more than one mission to complete, but Act 3 Tier 1 is different. Players will get only one mission in Act 3 Tier 1, and that’s also the simplest one to complete, apparently though. To begin with this mission, the first and most important thing that you need to do is to have a squad. Of course, in the Zombies mode missions can be done alone, but for safety, we always recommend having at least one teammate. Along with that, have grenades, powerful weapons, and lots of self-revive kits. Any powerful weapon you have will work for this quest. It doesn’t need you to Pack-A-Puch your gun.

Once you are ready with all these weapons and equipment, let’s focus on the first objective. It requires you to complete a Defend Ground Station mission. Defend Ground Station missions are scattered throughout the map. So, open the tactical map and look for them. We recommend not to select the ones that are in the medium or high-threat zone. Staying in the low-threat zone is always better. For further reference, check the map attached above.

Now that you have located the contract, go to the location and activate the contract. Remember, Defend Ground Station contracts spawn lots of mercenaries and even reinforcement helicopters. So, you will need to have teammates to deal with them. However, accepting the contract will spawn three Seismic Refractors in the area. Players must individually interact with them to activate them. This process will require you to kill lots of zombies and mercenaries.

Once you activate the Seismic Refractors, your next task will be to enter the building and upload the data on the computer. The computer is found on the ground floor and in an open space. As soon as you start uploading the data, mercenaries and zombies will spawn in hordes to kill you. Even reinforcement helicopters will come.

The uploading process will take some time and it is the time to complete your second and third objectives together. These objectives require you to kill 20 Mercenaries and maintain the computer health above 60%. We recommend the entire team stay close to the computer and fight the zombies and mercenaries. Eventually, you will reach 20 mercenary kills. If the upload process is remaining, protect the computer until it ends. Once the upload process ends, you will reach the fourth and final objective.

This objective wants you to exfil with the Death Perception recipe. This objective is not difficult. As soon as the upload process ends, a reward rift will appear giving you the Death Perception recipe. Pick it up and mark the nearest exfil point. Survive the waves of zombies until the helicopter arrives. Once the helicopter comes, board with the recipe, and your mission is done.

After you complete the mission you will get some items that you must save for later missions.

What are the Rewards of Two Factor Authentication Mission?

Rewards are the main attraction of a Call of Duty mission. Of course, progressing through the story matters, but rewards matter more than that. So, to motivate players to take up challenging missions, Activision prepared exciting rewards for them. But the rewards you get after completing the Two Factor Authentication mission compensate for all the efforts you have put in. Below we have listed the items:

Flawless Aetherium Crystal Acquisition
3000 XP.

If you are trying to figure out why the Flawless Aetherium Crystal Acquisition is a great reward, let me tell you this item is one of the hardest items to acquire. Using this Crystal players can give their weapon an instant level 3 Pack-A-Punch. However, we recommend not to use it randomly. Instead, save it for the Act 3 Tier 2 mission Most Firepower. This mission will require you to have a level 3 Pack-A-Punch weapon for the objectives.

About the XP, there’s nothing to explain. Getting 3000 XP will boost your rank significantly unlocking new perks and equipment.

That’s all you need to know about how to complete the Two Factor Authentication mission in Modern Warfare 3 Zombies. This mission is not challenging like others, but still don’t take it lightly. The fight to defend the computer’s health will be difficult as enemies will attack from every side. Moreover, you must complete all these objectives in one go. If you die, you will lose all progress and have to start from the beginning.
