Clearing Cookies Signs You Out of Nearly Everything

One site is misbehaving, somebody told you to clear your cookies, and you are about to press a button that affects every site you have ever visited.

There is a narrower version of that button, sitting in the same settings page, and it fixes the one site without costing you the other four hundred.

I checked how many browsers are installed on this machine first, because that number changes the answer more than anything else on this page.

What the big button actually does

Microsoft says it in one short sentence, and it is worth reading before you click.

⚡ Microsoft spells out the cost on its Edge cookies page. After deleting, "All your cookies and other site data will now be deleted for the time range you selected. This signs you out of most sites."

⭐ Every site. Every account. Every shopping basket. That is not a side effect, it is what cookies are for.

⚠️ Microsoft states what they hold: "Cookies are small pieces of data stored on your device by websites you visit."

⚡ And what they are for, in the same sentence: "remembering login credentials, site preferences, and tracking user behavior".

⛔ So the big button costs you the first two to get rid of the third. That trade is rarely the one you wanted.

The narrow button nobody uses

Same page in settings, and it is the one that fixes a single broken site.

⭐ Microsoft's own instruction for one site: "Select the down arrow to the right of the site whose cookies you want to delete and select Delete."

⚡ That clears exactly one site's data and leaves every other login where it is.

⚠️ Search the list by name. Every browser lets you filter it, and the site you want is usually listed under its plain domain.

⛔ This is the first thing to try, not the last. A site that will not log you in, or shows you as logged out on every page, is almost always its own cookies rather than yours in general.

The number that changes everything

Measured here, and most people have not counted.

⭐ There are four browsers installed on this machine, and each one keeps a completely separate cookie store.

⚡ Clearing cookies in one does nothing to the other three. They do not share anything.

⚠️ So if you cleared cookies and the problem persisted, check which browser you actually opened. People clear in Chrome and then test in Edge without noticing.

⛔ A work profile inside the same browser is separate again. Signing in with a second account creates a second store.

Cookies, cache and history are three different things

They sit next to each other on the same screen, and clearing the wrong one wastes your afternoon.

⚡ Cookies are how a site remembers you. Deleting them signs you out.

⭐ Cache is a copy of the files a site sent, kept so the page loads faster. Deleting it costs you nothing but a slower first load.

⚠️ History is only your own list of what you visited. Deleting it changes nothing about how any site behaves.

⛔ If a page looks broken or out of date, clear the cache and not the cookies. The caches on a Windows PC are a separate subject again.

When clearing cookies is the right answer

Four symptoms, and they are quite specific.

⭐ A site that logs you out on every page you click. Its cookie is corrupt or blocked, and clearing that one site fixes it.

⚡ A login loop that returns you to the sign-in screen forever. Same shape, same fix.

⚠️ A cookie banner that reappears on every visit. The banner cannot store your answer, usually because something is blocking it.

⛔ Or a checkout that empties itself. The basket lives in a cookie, and if it will not stick the cookie is not being kept.

⚠️ Clearing them is also a step after clicking something you should not have. What else to do, in the order that matters.

When it is not the answer at all

Three things people clear cookies for and should not.

⛔ A slow browser. Cookies are tiny. They are not what is slowing anything down.

⚠️ Privacy from your provider or your employer. Deleting cookies removes what sites store on your machine and nothing else.

⭐ Or a site that is down. If it is broken for everybody, your browser has nothing to do with it. Working out which of those you have takes two minutes.

The setting worth knowing about

Because it exists, and because it catches people out.

⚡ Microsoft describes an option that clears cookies every time you close the browser, and says of it: "every time you close your Edge browser all cookies and other site data are deleted. This signs you out of most sites."

⭐ Some people turn that on and forget. Then they wonder why they type their password into everything every morning.

⚠️ If you are being signed out daily and nothing else explains it, look for that toggle. It is on the same settings page as the delete button.

⛔ Turn it on deliberately or not at all. It is a real privacy setting and a real daily cost, and both halves are yours to choose.

Status: put together from Microsoft's cookie page on 28 August 2026, with the installed browsers counted here. ⛔ No browsing data, cookie, site name or history was read or published.

Does clearing cookies delete my passwords?

Not your saved passwords, but it does sign you out of nearly every site. Microsoft says plainly that deleting cookies signs you out of most sites. If your browser or password manager has your passwords saved, you can sign back in. If it does not, you will be typing them.

How do I clear cookies for just one site?

Every major browser lets you. Microsoft's own instruction for Edge is to find the site in the cookies list, select the down arrow to its right, and select Delete. That fixes one misbehaving site and leaves every other login intact, and it should be the first thing you try.

Should I clear cookies or cache?

Cache, in almost every case. A page that looks broken, stale or half-loaded is a cache problem, and clearing it costs you nothing. Cookies are what keeps you signed in, so clear those only when a specific site refuses to remember you.

Why did clearing cookies not fix anything?

Often because you cleared them in a different browser from the one with the problem. Each browser keeps its own separate store, and there are four installed on the machine used for this page. A second signed-in profile inside the same browser is separate again.

The Short Version

• Microsoft says plainly that deleting cookies signs you out of most sites.
• Clear one site's cookies first. The option is in the same settings page.
• Every browser keeps its own store. There are four on this machine.
• A second profile in the same browser is a separate store again.
• Cookies keep you signed in. Cache makes pages load faster. They differ.
• A broken or stale looking page is a cache job, not a cookie job.
• Cookies do not slow your browser down and do not hide you from anybody.
• If you are signed out every morning, look for the clear-on-close setting.

Where to Next

If a site keeps asking for a code and your phone will not fill it in, that is a different stored-data problem. Verification codes stop autofilling for specific reasons.

Find the one site that is misbehaving and clear only its cookies. That option exists in every browser and it costs you nothing else.

Check which browser you are actually testing in before you decide the clearing did not work. Four separate stores is four separate answers.

If the page looks stale rather than signed out, clear the cache instead and leave your logins alone.

And before you clear anything at all, make sure you can get back into the sites that matter. A password manager turns this from a bad afternoon into a minute.

If you have ever been signed out of everything and lost something you could not get back into, tell me which site in the comments. That list would be worth having before anybody presses the big button.
