Army Knowledge Online (Also Called AKO) is the U.S. Army’s private intranet. It is the biggest intranet in the world. The secure intranet is accessed through the Army’s public web page. All soldiers must sign up for an AKO account.

Army Knowledge Online (AKO) is one of the finest resources for today’s Army’s Modern Warrior.  AKO is available to the men and women of the Army serving in various posts around the United States and the world at large and to Army retirees and their family members of both active and retired service members.  The basic function of the AKO is to serve both the pre-eminent intranet service – and a single portal entry – for the United States Army.

The AKO is a tremendously useful system for the soldiers and their families and the Department of Defense (DoD) members.  The AKO links all of these elements – civilian workers, family members, and Army servicemen and women – and allows them access to various services, such as records, classes, accounts, and webmail.  Upon enlistment, registration on the AKO system is a requisite for all Army personnel.  Through this registration, today’s modern warriors will create an account and a login password that will enable them access to their private information regardless of whether they’re stationed at Fort Sill, OK, or a forward observation post in Afghanistan.

AKO Summary
AKO is a single enterprise web portal that provides the single sign-on capability for email, directory services, blogs, file storage, instant messenger, and chat and links and access to other related army websites (e.g., ATTRS, iPERMS, MEDPROS, etc). AKO Webmail is available to all components of the Army (Active, Reserve, and National Guard) and those who support the Army, including contractors, Family dependents, and Army Retirees. In addition, AKO offers the capability for users to build pages and file storage folders with access control capabilities to facilitate information sharing within the Army.

AKO’s Security

Military personnel must have a Common Access Card (or CAC for short) and a personal identification number to access AKO. Users logging in must also answer 3 out of 15 personal questions, further validating who they say they are.

AKO 2.0 offers new features.

Army Knowledge Online (AKO) is NOT being phased out — AKO 2.0 has more modernization and upgrades and new and enhanced capabilities to meet the needs of today’s Army.

The new AKO, named AKO 2.0, features a more mobile-friendly and modern design, improved navigation, the first-ever Army Directory connecting users to Army organizations, and a home page dedicated to military people, DOD civilians, and contractors.

Apart from a fresh design, AKO 2.0 will feature better search functionality and a responsive design that adapts to the user’s device, including mobile devices. Additionally, AKO 2.0 will enable soldiers and commands to do all Army business, both personal and organizational, including access to medical information, training data, and educational records, among other things.

AKO 2.0 will provide “the right user experience” based on the user’s status as a military member, contractor, or civilian by delivering relevant content to the user at the right time.

AKO 1.0, also known as AKO Classic, was decommissioned in early 2019, and the Classic portal’s full functionality is no longer unavailable. Individuals and groups should immediately migrate all existing files from AKO Classic to the AKO 2.0. The storage limit for individual files has been set to 500 megabytes; however, no limit has been set for organizational files.
