You're staring at a sluggish browser. Maybe Netflix is lagging, or that one government website won't load the "Submit" button no matter how many times you click. You know the drill. Everyone tells you to just "clear your cache and cookies." But then a cold sweat hits. You start wondering: will clearing cache delete passwords that you haven't written down in years?
Honestly, the fear is real. Nobody wants to be locked out of their primary email or banking app because they were trying to make a website load five seconds faster.
The short answer is a hard no. Clearing your cache does not touch your saved passwords. They live in a completely different "room" of your browser's memory. However, there is a massive catch involving cookies that most people trip over.
The big confusion: Cache vs. Cookies vs. Passwords
Computers are literal. If you tell a browser to "clear everything," it will happily nukes your entire digital life. But if you're surgical about it, you’re safe.
Let's look at the cache. Think of the cache as a scrapbook. When you visit a site like Reddit, your browser saves the logo, the fonts, and some of the layout images locally on your hard drive. Next time you visit, it doesn't have to download those images again. It just grabs them from the scrapbook. It’s a speed trick. That’s all. There is zero login data in your cache.
Cookies are the troublemakers.
These are tiny text files that websites drop into your browser to remember who you are. When you check "Keep me logged in," a cookie is born. If you clear your cookies, the website forgets you were ever there. You aren't "deleted," but you are signed out. This is where people freak out. They clear their cookies, go to Facebook, see an empty login box, and panic because they forgot their password back in 2019.
Then we have the Password Manager. Whether you use Chrome’s built-in manager, iCloud Keychain, or a third-party tool like Bitwarden or 1Password, these credentials are stored in an encrypted database. This database is separate from your temporary internet files.
Why the "Clear Browsing Data" menu is a minefield
When you open settings in Chrome, Firefox, or Safari, you don't just see one button. You see a list with checkboxes.

- Browsing History: Just a list of URLs you visited.
- Cookies and other site data: This signs you out of stuff.
- Cached images and files: This is the "safe" one.
- Passwords and other sign-in data: This is the "nuclear" one.
In almost every modern browser, the "Passwords" box is unchecked by default. You actually have to go out of your way to click it. If you leave that box alone, your passwords stay exactly where they are.
Real-world scenarios: When things go sideways
I’ve seen people lose access to accounts even when they swore they didn't delete passwords. It usually happens because of session tokens.
Imagine you’re logged into a crypto exchange. You clear your cookies but keep your passwords. You go back to the site. The site asks for your password. You realize you don't actually know it—it was just "remembered" by the session. If you haven't saved that password in the browser's actual Password Manager, and you were just relying on the session cookie to keep you logged in indefinitely, you’re in trouble.
Google’s own documentation for Chrome is pretty clear on this. They state that clearing cache only removes files like images to free up space. But they warn that "some sites may seem a bit slower because the content needs to be loaded again." They don't mention passwords because, fundamentally, the cache has nothing to do with them.
Mozilla Firefox handles this similarly. Their "Clear Recent History" tool lets you pick a time range. If you select "Everything" but uncheck "Active Logins" and "Form & Search History," your saved credentials remain untouched.
The nuance of "Form Data"
There is a middle ground called Autofill.
You know when you start typing your address or your email into a box and it magically finishes it for you? That’s not a password, but it feels like one. Clearing "Form Data" or "Autofill" will wipe that memory. It’s annoying, but it’s not a lockout.
Mobile vs. Desktop: Is there a difference?
On an iPhone or Android, "clearing cache" often happens at the app level.
If you go into Android settings and "Clear Cache" for the Chrome app, your passwords (which are synced to your Google Account) are totally fine. If you hit "Clear Data" or "Storage," you're essentially resetting the app to the day you bought the phone. Even then, once you sign back into your Google account, your passwords usually sync back down from the cloud.
Apple’s iOS is even more protective. Safari’s "Clear History and Website Data" is a one-button nuke. It clears history, cookies, and cache all at once. It will sign you out of websites. But your passwords? They are tucked away in Settings > Passwords (FaceID protected), and Safari will just offer to autofill them the moment you go back to the login page.

How to stay safe while cleaning house
If your browser is acting like a brick and you absolutely need to clear the junk, follow a "safety first" protocol. It’s better to be annoyed for five minutes than locked out for five days.
1. Check your Password Manager first
Before you touch any settings, go into your browser's password list. In Chrome, it's chrome://password-manager/passwords. Make sure the account you're worried about is actually listed there. If it's not there, you’ve been relying on a cookie, and clearing it will "forget" you.
2. Use the "Surgical Strike" method
Don't clear everything from the beginning of time. Most browsers let you clear the last 24 hours or the last hour. If a site just started acting up, try clearing the most recent data first.
3. Specific site clearing
Did you know you can clear data for just one website? In Chrome, click the little padlock or "tune" icon next to the URL. Click "Cookies and site data" and then "Manage on-device site data." You can delete the junk for that specific site without signing yourself out of every other corner of the internet.
The Verdict
So, will clearing cache delete passwords? No.
You can clear your cache every single day and your saved passwords will remain safely tucked away in your browser’s encrypted vault. The only way those passwords disappear is if you manually check the box labeled "Passwords" or "Sign-in data" during the cleaning process.
The real danger isn't losing the password; it's the inconvenience of being signed out of 50 different tabs because you cleared your cookies along with the cache.
Practical Next Steps
- Audit your logins: Go to your browser settings and verify that your most important accounts (email, bank, primary social media) are actually saved in the password manager and not just kept alive by cookies.
- Enable Sync: Ensure your browser sync (Google Sync or iCloud) is turned on. This backs up your passwords to the cloud so that even if you accidentally wipe your local data, you can recover them.
- Use a Dedicated Manager: Consider moving away from browser-based password saving and using a standalone tool like Bitwarden or Dashlane. These are immune to browser "clearing" mishaps.
- Selective Cleaning: The next time you clear your browsing data, carefully read the checkboxes. Uncheck "Cookies" if you only want to fix a visual glitch on a website, and always keep "Passwords" unchecked.
