I have seen some search terms on this site lately involving the same query as described in the title of the article: the EUC Unified Access Gateway (UAG) default password. I would like to answer those queries in this post. And to be short, direct and for some blunt, there isn’t any default. You will have to set the password of root and the password of admin in the deployment of the UAG appliance, or is changed via VAMI or the Admin console. I have done this myself a couple of times, with all sorts of VMware appliances, but the main thing for UAG, AP and IDM is that redeployment is much easier than trying to fix issues (and is stable, saves hassle and breaking heads). But what you would like if something goes amiss with deployment or changing, probably regarding some required special characters of admin, is to use some of the options to regain access to the system and try to find out what went wrong (we want to know the why don’t we?!?). If you have worked out the why with the option of regaining access, it is still advisable to redeploy with that knowledge. The procedure of resetting the passwords of root and admin are described in the rest of the article. You might just need the admin procedure if your root password is known and working.
