To facilitate client to client communications, they should add a who-does-it-serve (short WHO DIS) system to get contact information of already reserved names.
What certainly comes to mind is the recent leak of the Github SSH Host key where such a mishap opens the possibility of MITM attacks if no appropriate actions are taken.
Practical examples of common sense could be pipelines in gitlab where a ssh connection is started. In such situations, the easiest solution is to just ignore the fingerprint but of course if the gitlab server network environment is compromised, a MITM attack is very possible.
Upon launch, I was of course disappointed with the state of the server and the online only nature of it. But the larger problem for why this game was a failure was the simple problem of way to little space to build a city. The whole concept of a few 1km x 1km city patches in a shared world to build in was flawed from the start. I want to build gigantic cities with elaborate public infrastructure and rivers full of sewage. Cities: Skylines simply was a much better fit for what makes the city building genre appealing.
I find it a bit shortsighted to center the blame for a boring game on its launch date debacle. Many other games with similar problems at launch became hits.
Seems like OP just performed a stress test on his website as he is the "Webmaster of https://hvac-learning.com an HVAC elearning website"[1]. Hopefully you can figure out something! Thank you for educating about such technology!
Don't Android phones have a similar feature with a linked Google Account? I once needed to contact the old Owner of an Samsung phone because of such an account lock.
You would, in theory, just need to remember your one strong password, like with a password manager (except 2fa and such). The benefit is that you don't need to store anything, just remember your master password and the "salts" are obvious to you, but an attacker with the clear text password would not be able to differentiate a random password to a pashword result. From the generation time and cpu usage on pashword I'd also guess bruteforce is very hard even if you would know it's generated.
