Reset Eset Nod32 Admin / Settings Password

So I came across a big problem at work today. We had installed Eset Nod32 v 3.0.695 on 300 sites each using the same admin password.

The guy who sorted this all out, with all his wisdom, forgot the password!!

Anyway after 3 days straight of googling I came across a few obscure russian sites that pointed me in the correct direction along with a slightly helpful guide on Eset’s knowledge base.

The page from the Eset Knowledge Base provided me with a helpful unlock tool, but with a downside. I had to run it on the computer with the locked Eset and email the code it provides to Eset Support and wait for a reply.

Although this is great for just one or two computers with locked Eset’s, I had over 300.

Now this Russian site I found, it provided me with an unlock code generator. Used in conjunction with the official Eset Unlock tool I managed to unlock and remove the Password!

Below is the guide and a link to the files you will need.


1-      Open Eset Unlock Tool

2-      Write down code displayed.

3-      Open Unlock Code Generator

4-      Delete existing code displayed and replace with one that you got from the Eset Unlock Tool

5-      Hit .gen (generate)

6-      Copy the generated code into the Eset Unlock Tool

7-      Press Enter… Done!

  1. Good day! I could have sworn I’ve been to this site before but after browsing through some of the post I realized it’s new to me. Anyways, I’m definitely happy I found it and I’ll be bookmarking and checking back frequently!

  2. works for
    eset smart security 5 successfully successfully successfully successfully successfully successfully

  3. many many many many many maaaaaaaaaany
    thanks my lord


    any one faced it’s not working just try to restart your pC and
    try again and it will working successfully

    it about my personal experience


  4. Cannot help there unfortunately as it is a different Eset product, this tool only works with Nod32 as far as I know.

  5. We tested it with Nod32 version 4. Unfortunately we use Eset Endpoint rather than Nod32 now so are unable to test, however no harm can be done by trying!

  6. am running eset smart security 5 and its not working for me… any help please…. i cant even uninstall it… and i can remember the password i used either…

  7. Thanks. I don’t have 300, only 25 computers to unlock but it is much easier when not having to contact ESET. This tool rocks 🙂

    Malicious users will most definitely benefit more from this than anybody else, very nice of you indeed. 🙂

  9. Hello,
    At which point do you get this error message?
    What operating system are you running?
    Are you running within a domain environemnt?
    Are you able to access the local admin account, or another account with privileges to run applications?

  10. Hm, does not appear to work for me. Followed the steps exactly. Keep getting “ERROR: Permission denied”. Running version 4.0.437.0

  11. Hi, i’ve searched like 30min in net for “Unlock Code Generator” and didnt find. Please, give me link to download this program.


  12. Thanks Deset for your tip! I managed to run both tools from a memory stick. It seemed to work but ESET is still locked!? Tried with safe mood too but sadly no result.

  13. The Eset Unlock Tool should work on the PC with ESET running on it as it is an official Eset utility.
    If you have access to another PC, you can run the Unlock Code Generator on there and follow the above steps as normal, although you will obviously not be able to copy & paste the codes!

  14. Very useful tool, I would really need it. But I’m in a “Moment 22” situation here. ESET won’t allow me to download this and I cannot turn off ESET because I have forgotten my password 🙂

  15. A genuinely exciting examine, I could possibly not concur entirely, but you do make some genuinely legitimate points. 221196

  17. Easily done. I forget my password/PIN all the time and it is quite annoying especially with credit cards.

  18. That is so funny. The sad thing is that it could happen quite easily. I change my password all the time because I can never remember them.
