Clearing cache will not delete your saved passwords
Your cache is a storage folder for temporary files — images, scripts, and page layouts that websites read to your device so they load faster next time. Your passwords are stored separately, in a different location, managed by your browser's password manager. Clearing the cache touches one; it does not touch the other.
The confusion happens because clearing cache and clearing passwords are both options in the same browser menu, and they sound related. They are not. Think of it like emptying your kitchen trash (cache) versus throwing out your address book (passwords). One does not affect the other.
Key Takeaways
- Cache stores temporary website files to speed up loading; passwords are stored in a separate password manager database that clearing cache does not reach.
- Clearing cache is safe to do regularly and will not log you out of accounts unless you also clear cookies, which is a separate checkbox.
- If you want to delete a saved password, you must go to your password manager settings, not the cache-clearing menu.
- Clearing cookies (a different thing from cache) will log you out of websites, but clearing cache alone will not.
Where your passwords actually live
When you save a password in Chrome, Firefox, Safari, or Edge, the browser stores it in an encrypted database managed by that browser's password manager. On Windows, Chrome passwords live in a folder only Chrome can read. On Mac, Safari passwords go into the Keychain, which is Apple's system-wide password vault. Firefox stores passwords in its own encrypted file.
Cache files live in a completely different folder — usually called "Cache" or "Temporary Internet Files" — and they contain only images, stylesheets, and JavaScript code. A website cannot store your password in the cache; the cache is not designed for sensitive data. Your browser's password manager is.
What actually happens when you clear cache
When you go to Settings or Preferences in your browser and choose "Clear browsing data" or "Clear cache," you are deleting temporary files that make websites load faster. The next time you visit a website, your browser downloads those files again. This is why some people notice websites load slightly slower after clearing cache — the browser has to re-read images and code it had stored locally.
You will still be logged into your accounts because login sessions are stored in cookies, not cache. Cookies are small text files that remember that you logged in; they are separate from cache and separate from passwords. If you want to stay logged in after clearing data, you must uncheck the "Cookies" box and check only "Cache" or "Cached images and files."
The difference between cache, cookies, and passwords
| What it stores | What it does | Clearing it affects |
|---|---|---|
| Cache | Images, scripts, stylesheets downloaded from websites | Page load speed (slightly slower until files are re-downloaded) |
| Cookies | Login sessions, site preferences, tracking data | Whether you stay logged in; whether sites remember your choices |
| Passwords | Encrypted login credentials stored by your password manager | Nothing — passwords are not affected by clearing cache or cookies |
Many people clear cache and cookies together because both are temporary and both can improve privacy. But they do different jobs. Cache is about speed; cookies are about remembering you; passwords are about security. You can clear one, two, or all three depending on what you want to accomplish.
When you actually need to delete a saved password
If you want to remove a password your browser has saved — because you changed it, or you no longer use that account, or you do not want the browser to remember it — you go to your password manager, not the cache menu. In Chrome, this is Settings > Passwords. In Firefox, it is Preferences > Privacy & Security > Passwords. In Safari, it is Preferences > Passwords. In Edge, it is Settings > Passwords.
From there, you can search for the site, see the saved password, and delete it. This is the only way to remove a saved password. Clearing cache will not do it.
Why people think clearing cache deletes passwords
The confusion comes from the browser menu itself. When you open "Clear browsing data" or "Clear cache," you see checkboxes for cache, cookies, passwords, browsing history, and sometimes autofill data. Because they are all in one menu, it feels like they are all the same type of data. They are not. The browser groups them together for convenience, but they are stored separately and managed separately.
If you check the "Passwords" box in that menu, then yes, your saved passwords will be deleted. But the default is usually unchecked. Most people clear only cache and cookies, which is why they do not lose their passwords. If you have cleared passwords by accident, you will need to re-enter them or reset them on the websites themselves.
What you should actually clear and how often
Clearing cache once a month is reasonable if you want faster browsing and a bit more privacy. Clearing cookies is more aggressive — it logs you out of everything and removes tracking data, which some people prefer. Clearing passwords should be intentional and rare, only when you have a specific reason to remove a saved credential.
If you are concerned about privacy on a shared computer, clearing cache and cookies regularly makes sense. If you are the only user of your device, clearing cache is optional — it does not hurt anything, but it is not necessary for security. Your passwords are safe either way because they are encrypted and stored separately from the temporary files you are clearing.
Frequently Asked Questions
Will I be logged out of my accounts if I clear cache?
No, not unless you also clear cookies. Cache and cookies are separate. If you uncheck the cookies box and clear only cache, you will stay logged in. If you check both boxes, you will be logged out of everything because cookies store your login sessions.
If I clear cache, do I have to re-enter my passwords?
No. Your passwords are stored in your password manager, which is not affected by clearing cache. Your browser will still remember your passwords and can fill them in automatically the next time you log in.
Can clearing cache slow down my computer?
No. Clearing cache frees up storage space. You might notice websites load slightly slower the first time you visit them after clearing cache because your browser has to re-read images and code, but your computer itself will not be slower.
What if I accidentally cleared my passwords?
You will need to reset them on each website. Go to the login page, click "Forgot password," and follow the recovery steps. Once you reset a password, your browser can save it again if you choose to let it.
Is it safe to clear cache on a public computer?
Yes. Clearing cache removes temporary files and is a good privacy practice on a shared device. If you also clear cookies, you will remove login sessions. Do not check the passwords box unless you want to delete saved credentials, which you should do on public computers.
