## Quick answer Army Knowledge Online (AKO) was the Army’s primary web portal for nearly two decades, serving as a "one-stop shop" for email, training, and personnel data. Launched in 1999 as a pilot, it was officially retired for most users in 2014 and replaced by a decentralized ecosystem of specialized tools like the Enterprise Access Management Service (EAMS-A), Army 365 (Microsoft 365), and the Integrated Personnel and Pay System - Army (IPPS-A).

In detail

### The Rise of AKO (1999–2010) AKO began as a General Officer Management Office project in 1999. Its goal was to bridge the gap between disjointed legacy systems and provide a single login (SSO) for every Soldier. By 2005, it was the world’s largest corporate intranet, serving over 2 million users, including Active Duty, Guard, Reserve, retirees, and Family members.

At its peak, AKO provided: * **Official @us.army.mil email:** A lifelong email address for Soldiers and retirees. * **Knowledge Management:** Document libraries and collaboration folders. * **Single Sign-On (SSO):** Access to the MyPay system and the Army Learning Management System (ALMS).

### The Decline and "Sunset" (2013–2021) The transition away from AKO happened in waves. The "Classic" AKO began its sunset in 2014 because the platform was built on aging technology that couldn't handle modern security requirements or the massive jump to cloud computing.

* **2014:** Retiree and family member accounts were transitioned to more limited access. The famous @us.army.mil email accounts for most non-active users were deactivated. * **2019–2021 (AKO 2.0):** A brief attempt at a "modernized" portal (AKO 2.0) was launched but proved redundant as the Army shifted toward the **Army 365** (Microsoft-based) environment. It was officially shuttered in June 2021.

### What Replaced AKO? There is no single "AKO" today. Instead, the Army uses several specialized platforms:

### Modern Identification The most critical evolution post-AKO is the **DS Logon**. This is the credential that replaced the simple AKO username/password for retirees and family members to access TRICARE and VA benefits.

## Who this applies to * **Active Duty, Guard & Reserve:** These users migrated to **Army 365** and **IPPS-A** for all administrative and operational tasks. * **Retirees:** Must now utilize **DS Logon** via the DMDC to access healthcare records and tax documents. * **Army Families:** Access TRICARE and benefits through the **MHS GENESIS Patient Portal** rather than the old AKO "Family" links. * **Army Civilians:** Managed via the same **Army 365** environment as uniformed personnel.

Common scenarios

### Scenario 1: A Retiree Checking Pay In 2008, SFC (Ret.) Miller would log into AKO to click a link for his 1099-R. In **2026**, Miller must use a **DS Logon (Level 2)** or a **CAC** to log directly into **myPay (DFAS)**. There is no central Army portal to jump through anymore.

### Scenario 2: A Soldier Updating Their Record In the mid-2000s, a Sergeant would check their Enlisted Record Brief (ERB) on AKO. In **2026**, the ERB is dead; the Soldier must log into **IPPS-A**—the Army's $1B+ personnel system—to view their Talent Profile and request leave (transitioned from the old DA 31 paper forms).

### Scenario 3: Checking TRICARE Coverage A spouse previously used AKO to find medical links. Today, they go to **TRICARE.mil** or the **MHS GENESIS Patient Portal**. If they live in the West Region (managed by **TriWest** as of 2025/2026), they log into the TriWest portal using their DS Logon to check 2026 copays (e.g., ~$38 for a TRICARE Select primary care visit for Group A retirees).

## Related terms * **Army 365:** The Army's implementation of Microsoft 365 (Teams, Outlook, SharePoint). * **CAC (Common Access Card):** The physical smart card required for most Army system access. * **DS Logon:** A secure identity credential used by those without a CAC to access DoD sites. * **IPPS-A:** The online human resources system that consolidated over 30 legacy systems. * **MHS GENESIS:** The unified electronic health record system used across the military.
