Did you log out of any other device that you might have possibly logged in? That's the only case where you get logged out, unless you're hacked. Change your email and password if you haven't. And also, remove the secret question if you have kept it, its a big vulnerability.
No, I only use this PC for my BitcoinTalk account. I already changed everything (password for my email, bitcoinTalk, my hosting password, activated 2FA etc, every possible stuffs).
Thing is I changed them after I received the
email here. Then I was doing other stuffs, actually replying
marlboroza (composing the message). When I compose I basically do preview every now and then, that time when I click preview then it was asking me to login again. It stopped my heartbeat for few seconds. Immediately, I tried to login and it was a success.
That bought me this thinking that if theymos is actually working on the server? My credentials were secured earlier than this happened.
I removed my secret question long ago when I learnt that recovering an account using security question eventually locks an account.

There are no such way for my browser. My PC is fairly (actually very) secure. I am also a very advance user in terms of computer and technology.
