As of 2026, ESET has phased out direct in-software conversion for some older versions. However, there are three reliable methods to convert your old credentials into a brand new License Key.

If the direct converter tool is temporarily unavailable (or if you cannot find it due to website redesigns), you can use the "Add License by Username" feature within ESET HOME.

This method accomplishes the same thing as Method 1. The keyword here is "new" — because even if you add via the old method, the backend generates a new License Key for your account.

When searching for "eset convert username and password to license key new," you may stumble upon third-party tools, cracked keygens, or "free converters." Avoid these at all costs.

You cannot directly convert an ESET username and password into a license key. The correct approach is to use the old credentials to retrieve a modern license key via ESET HOME or Support. If the credentials are from an unsupported or expired license, no conversion is possible – you must purchase a new subscription.

Actionable Advice: If you still have a valid Username/Password, do not attempt to find a converter. Instead, log into my.eset.com or contact ESET Support immediately. If the license is very old (pre-2015), it is almost certainly expired and non-convertible.

Converting legacy ESET credentials (Username and Password) into a new License Key is necessary because modern ESET products no longer support the older activation method. You can perform this conversion through the ESET software interface or the official business portal. Method 1: Using the ESET Application

If you have an older version of ESET installed (such as Version 9), you can convert your credentials directly within the software:

Open your ESET product and select Help and Support from the left-hand menu. Click Change License in the bottom right corner.

Choose the option: "I have a Username and Password, what do I do?".

Enter your legacy UserName and Password in the fields provided and click Convert.

Your new License Key (formatted as XXXX-XXXX-XXXX-XXXX-XXXX) will be displayed for you to copy and use for activation. Method 2: Using the ESET Business Account Portal

For business or multi-seat licenses, the ESET Business Account (EBA) portal is the standard tool for migration:

Access the Converter: Go to the official ESET License Converter page.

Enter Credentials: Provide your legacy Username and Password and click Convert.

Registration: If the license is not yet registered, you may be prompted to complete a registration process on the portal to link the license to an email address.

Receive Key: Your new key will be provided instantly on the screen and typically sent to your registered email address. If You Lost Your Legacy Credentials

If you cannot find your original Username and Password, you can use the ESET Lost License page to have your subscription details resent to the email address used during purchase. How to activate ESET Version 9 with a Username and Password

The modernization of ESET's licensing system has shifted away from legacy username and password combinations toward a unified License Key format (XXXX-XXXX-XXXX-XXXX-XXXX). This change ensures compatibility with newer product versions and simplifies license management through centralized portals like ESET PROTECT Hub or ESET Business Account (EBA). Methods for Converting Legacy Credentials

For both home and business users, several official paths exist to transition old credentials into the new key format:

Online License Converter: The most direct method is using the ESET License Converter. You enter your legacy username and password, and the system generates a corresponding license key.

In-Product Conversion: Users running older versions (such as Version 9) can often convert directly within the software. By navigating to Help and Support > Change License, you can select the option "I have a Username and Password, what do I do?" to trigger an automatic conversion.

Business Account Portals: For enterprise environments, legacy credentials should be added to the ESET Business Account or the newer ESET PROTECT Hub. Once these credentials are registered, they are automatically treated as license keys within the management console. Why the Change?

This transition is part of a broader infrastructure update. The old ESET License Administrator (ELA) reached its end of life on June 30, 2022, and was replaced by more robust cloud-based management tools. The new license key format is required for:
