I blame the North Koreans.

Caps lock?

Turn on SteamGuard

I've ran into a few instances where I'm sure I typed in my password correctly and it took 3 or so tries before it let me through. Unsure why that is, possibly an issue with the login server?

Good, good, all is going according to plan. Now... I wait...

cooincidences... they're the reason that superstitions exist

Over reacting.

Happened some times. It's like failing to plug your pendrive on your PC, then you flip it and fail again.
I don't know what sorcery is this.

Happened once. Steam crashed, couldnt log back in for a while...thought my account was stolen, but later it worked again

well a good welcome back to you too... I really doubt anyone would jack your account after GIVING you a gift, ive had my password bug sometimes too it happens, only when i login on the website though.

Happened to me a few times. You type in your password and it's not recognized. End up trying it over and over and after 5-6 times if finally logs in. I blame Steam community being down so often when it happens.

Jesus, it happened again, this time I tried through mobile and it didn't worked neither, so I just reserved my password twice, can someone please explain me this?

Now I'm scared, why is my steam browser site now asking me for my humanity every time I login now?

I need an answer now I'm too worried for this.

Just quit.

You should try changing your e-mail and your password again. If it keeps happening, try to make some scans on the pc.

I do not know the answer to your problems but I have a few questions. Do you run a spy sweep routinely or have any cleaning software of the sort for cookies, etc. It could be that maybe some malicious cookies or software could have infected your pc and thus maybe something is intervening. There are some good addons for Firefox that protect from such cookies getting onto your computer and tracking you or possibly storing your info. I use Cookie Monster and NoScript to prevent any such intrusions and I still get infected from time to time. Good luck! If all else fails just contact steam support and provide them with info of your bank account, etc. and they will retrieve the account for you. I've had a couple of scares while going between my sons account and mine and forgetting e-mails and passwords so I came close to locking myself out of one of the accounts. It happens to the best of us but good luck hope your able to get your Steamin' back on!
