If you have an existing Username and Password for your ESET product, you can convert them to a License Key.

Frequently asked questions

Why do I need a License Key?

When you have purchased a license for an ESET product, you have received an email from ESET containing your ESET-issued Username and Password. This email is delivered to the email address used at the time of purchase.

ESET introduced a new License Key (previously known as Activation Key) that replaces Username/Password license credentials. Therefore you will need to convert your Username/Password credentials here to activate latest ESET products.

Are my Username & Password still valid?

You can renew your license with renew discount up to 60 days before it expires, or up to 60 days after. Existing customers with valid licenses can upgrade to the latest version of their ESET product for free. For more details about upgrading to the latest version read the Knowledgebase article.

It has been more than 60 days since your license expired. Your license is not eligible for renewal pricing.

Does this affect the validity of my license?

Replacing Username and Password with License Key will not have any effect on your license. The License key represents a unique string in the format XXXX-XXXX-XXXX-XXXX-XXXX which is used for identification of the license owner and for activation of the license as well as the license credentials.
