Ladies and gentlemen, I have news: No documentation will tell you that "THERE IS NO WAY TO RESET IT".
You can stop reading, suck it up and start over from scratch or read my dilemma! 😄
If you forget your admin password, you will be locked out without access to your appliance. There is no procedure or app that will help you to gain access to it again. The only way is by doing a factory reset and to start typing all over again. That means the configuration you had, should be created again. You will have to make again: All the VLANs, VPNs, users, open ports, closed ports, blocked websites, unblocked websites, objects, etc.
Unless you are smarter than me and have documented all your changes and configurations, which I did not, then it will be easier to get back into your feet.
What happened to me is that I received an RMA appliance, created a default account, and "activated it, but it did not download the licenses (red flag), so anyways, I restored my configuration everything was perfect. I was able to log in with my admin. All my users and devices were happy. Then I created a ticket to ask for support to activate the license. I was recommended to do it using the webui "home/license/Activate" or to do it "manually" with the license received from tech support.
While waiting for advice, "because the user center was down," I needed to wait for hours because that could have been the cause. I decided to change my admin id and password for security reasons. I never thought that I could need to factory reset the device again. So after updating, I made notes with the "new" username and password and deleted my old admin/pass (mistake#1). Usually, I save a copy of it for crazy reasons, BUT IN THIS PARTICULAR case, I did not.
Guess what? The recommendation was to factory reset the device and activate the license with a new xml file. I happily did it, created a basic default configuration, and took notes of temporary id n pasw. Followed the tech support recommendations, the appliance was finally licensed and I was at peace and hopeful. Now it was time to restore my configuration. Oh Boy!, I forgot that after restoring my old setup, it will populate the old user admin and pass, and the temporary one will be lost.
I spoke to the tech support guys, and they explained to me that it's a security feature, etc., but I need more than that because, in the end, all the hours invested in my configuration and specific business needs are gone. Now, I have to start over from scratch, day 0.
So if you are in a similar situation, do not look more!
The solution, Do the following:
Get coffee, and order a medium size pizza because it is going to be a long night. Call home and tell them you are not going tonight, and start typing and setting up your configuration. Hopefully, you have documented everything, which I still need to do.
Good luck!
