Steam logs me out

Tried clearing cache and cookies?

I don't have this issue and I also don't use mobile authenticator. Perhaps Linerax's suggestion of clearing cache and cookies would fix the problem, definitely give that a try.

if community is down, then you wont appear as logged in on the store

i always use the browser rather than the client, never had anything unusual

if you are fiddling with https manually or with https-everywhere addon, you may run into issues

if you don't check remember me checkbox, you will need to re-login when session ends

I had to log in again the other day when the store was down for a bit one morning but that's the only time in recent memory

I have same issues droped from browser and Idle Master sometimes.

happens to me after incorrectly shutting down my PC =d

Haven't noticed it in the browser yet, but Idlemaster makes me re-log a couple times a day.

Happens all the time if you buy gifts/do trades/or use/login on sites with valve's account system or most commonly if
you use more then one device to access your account (= 2 computers/2browsers) ... might have increased since SGMA.

Good to hear that at least some of you have the same problem. Thank you for your replies :)

this happens to me on chrome when buying stuff from the store or sending gifts, but firefox remains logged in forever (it's been months so far).

It has been really bad today. I got logged out at least 20 times. Does anyone else see this happening more frequently?

Also, have a Fre‎e Game Bump™

• If you to‎ok the key, please (1) activate it on your ac‎count, and (2) reply to let me know so that I can remove the link (otherwise your email ad‎dres‎s will remain visible).
• Please don't take the key if you already own the game or are not interested in it.

I've recently been getting constantly logged out at least twice a day even though I always leave it open in the background. It happens for no reason.

I've had this problem since I installed Enhanced Steam. The solution was, deactivate SteamGifts Steam Ratings.
So far, in a few hours since deactivated it, haven't logged out yet.
