I use Chrome on a personal PC on which I am the only user. I am logged into several websites, all of them with the "stay logged in" tickbox checked. Even so, very often when I go back to some of these websites, I find I am logged out and need to log back in every time. This happens even if the previous visit was recent; I suspect the critical action is the restarting of the browser rather than time elapsed.

Strangely, this problem happens only with certain websites (among them, booking.com, leo.org, oebb.at) but not with others (such as the StackExchange sites, or the Google sites such as Gmail/YouTube)

I used to think this is a problem with those former websites, but I realise it probably has to do with Chrome itself. What can I do to diagnose it? The only way I'd know how to do this is to disable each extension (add-on) at a time to see if any one of them is at fault, but that would take quite a while.

I am on Windows 10 and let Chrome update itself (currently at v77.0.3865.90).


It is possible that your cookies are corrupt. It are cookies where the login information is stored. If this is corrupt, it may not update properly, and thus the expiration date is set to a date in the past, which effectively means that every time you login, the cookie is expired and it requests you to login again.

To solve this problem, clear your cookies. This will log you out of every site though, but once you login again, it should stay.

  • Would this explain why this problem is so selective, with some sites never logging me out? I tried clearing all cookies a while ago but can try again... – z8080 Oct 15 at 20:55
  • Yes. If some cookies are corrupt but not all, some cookies will update correctly, while others will fail, basically. – LPChip Oct 16 at 16:16
  • Thanks! For now it seems to work but I'l report back if the fix is durable – z8080 Oct 17 at 11:35
  • It will be until the cookies go corrupt again. If this happens in a short fashion, something else is wrong. This could be an unstable browser crashing or a failing harddrive. – LPChip Oct 17 at 11:41

    The 2 sites may actually set a short lifespan for the cookie and log you out simply because the cookie expires normally. If this is the case, then it is normal behavior for that site and only the website owner can fix it. You can run CrystalDiskInfo to read the SMART info for your hardware to rule out any hardware defects. Also, you can verify the behavior by using a different browser and/or pc. If it does not happen there, it is something on your pc. If it happens there also, it is something with the website itself. – LPChip Oct 21 at 9:50
