What is authentication data (username and password) and what is its purpose?

KB Solution ID: SOLN373|Last Revised: September 13, 2013

After purchasing your ESET security product, you will receive authentication data (username and password). This data is used to download the product, to receive virus signature and program component updates.

Usernames and Passwords

Remember to enter your Username and Password exactly as they are written:

  • The username and password are case sensitive
  • The hyphen in the username is necessary
  • The password is ten characters long and all lowercase
  • If you are copying and pasting, make sure you don't select an extra blank space
  • We do not use the letter L in passwords (use the number one (1) instead)
  • A big '0' is the number zero (0); a little 'o' is the lowercase letter o

I forgot my Username and Password


In addition to a username and password, ESET Remote Administrator, ESET Mail Security for Microsoft Exchange Server, ESET NOD32 Antivirus for Kerio Control and ESET NOD32 Antivirus for Kerio Connect require license keys for full functionality. License keys and authentication data for these products are delivered to the email address used at the time of purchase (contact email).

The license key contains the following information: product name, owner, number of licenses, and expiration date. This information is displayed in the tab, which is also used to add the license file to the system. In order to upload a license key, please follow the steps below:

License keys (Business Edition users):

  1. Open ESET Smart Security or ESET NOD32 Antivirus. How do I open my ESET product?
  2. Press the F5 key on your keyboard to open the Advanced setup window.
  3. From the Advanced Setup tree on the left, click Miscellaneous Licenses.
  4. Click Add, double-click the appropriate .lic file, and click OK.
