Do Surfaces Restrict You From Using a Previous Password Again When You Change Password
Advertisers have found a new way to rail you. According to Liberty to Tinker, a few ad networks are now abusing tracking scripts to capture the e-mail addresses that your password manager auto-fills on websites.
Simply it gets worse: they could use that tech to capture your passwords too, if they wanted. This affects anybody using a password manager, whether it's a built-in password manager like the 1 in Chrome, Firefox, or Edge, or a browser extension similar LastPass. As a upshot, you should probably disable the autofill feature to prevent this from happening.
How Autofill Is Leaking Your Information
When y'all relieve your username and countersign on a website, your countersign manager remembers them. From that point forward, information technology will attempt to automatically fill them into username and password boxes information technology sees on that website. This makes signing in faster, every bit you just have to click "Login".
But some tertiary-party advertising scripts—the ones that nigh every website out in that location uses—are starting to use these to runway you. They run in the background, create fake login and countersign boxes you can't even see, and captures the credentials your password manager fills into them.
You can see this problem for yourself by visiting this demonstration page. Fill in a false email address and countersign, and you'll exist prompted to salvage it in your browser's password manager. Continue, and information technology will exist autofilled in the background, with the script capturing the email address and countersign.
This demonstration site doesn't currently bear witness any problem if y'all utilize LastPass, only anything that automatically fills usernames and passwords with no user intervention—LastPass included—is theoretically vulnerable.
Y'all Need Unique Passwords Everywhere, So Password Managers Are Still Essential

This problem demonstrates the importance of using unique passwords on every website. It's not merely a theoretical attack—it's actually existence used by advertisers on 1110 of the acme 1 million websites today, according to Freedom to Tinker. Advertisers are currently just using this technique to capture usernames and email addresses, but there's nothing stopping them from capturing passwords as well, if one was in a especially nefarious mood someday.
If an advertiser did capture your countersign on a website, the worst someone with that data could practice is sign into that website. That'due south not ideal, but it's non the worst thing that could happen. if you use the same countersign for that website every bit y'all exercise for your email account, that person could and then admission your email account and use it to gain access to your other accounts. That's the worst that could happen.
This is why we still recommend using a password manager, no matter what. With all the different accounts the average person has online, and the frequency of attacks confronting these websites, it's imperative that you utilise a unique password for every site yous visit. The best way to do that is with a password manager—don't throw the baby out with the bathwater.
Protect Yourself By Disabling Autofill
However, you tin can even so mitigate some of your take a chance from these scripts past disabling autofill in your password managing director. For example, if you apply LastPass (which is not currently affected past these scripts, merely theoretically could exist), the autofill feature fills login fields with your credentials so you tin can just click "Login". If you disable the autofill characteristic, you'll accept to click the LastPass icon in a password field and click your username to fill your saved information. You'll only do this when trying to sign in, and then this should protect your credentials from being scooped up. Y'all're no longer spraying them all over every page.
Y'all could also just copy-and-paste usernames and passwords from your password director of choice, and that would make yous even safer—but significantly less convenient. We think choosing to manually initiate autofill only on login pages should be a good middle ground between security and convenience. If those login pages were compromised with such a script, nothing could help you, anyway—the script could read your login details fifty-fifty if yous copy-and-pasted or manually typed them in.
Unfortunately, near browser password managers don't allow you to disable autofill. There'south no way to disable the autofill feature if yous're using the integrated password manager in Google Chrome or Microsoft Edge, for example. Chrome does have an option to disable autofill, just it just disables autofill of data similar addresses and phone numbers, not passwords. There is an option to disable autofill of passwords in Mozilla Firefox's password managing director, but it's subconscious in about:config.
If you're using the born password manager in Chrome or Edge, we encourage you to switch to a tertiary-party password manager that offers more control, similar LastPass or 1Password. 1Password isn't afflicted by this problem considering information technology doesn't include an automated autofill feature.
In LastPass, you can disable autofill by clicking the LastPass extension button on your browser toolbar and clicking "Preferences". Uncheck the "Automatically Fill Login Information" option under General and and so click "Save" to relieve your changes.
If you want to go along using Firefox's password manager, you should blazon "well-nigh:config" into Firefox's address bar and press Enter. You'll come across a warning screen informing you that changing various settings here could cause problems. Don't worry—if you only change the single setting nosotros signal out, you'll be fine. Click "I accept the risk!" to continue.
Blazon "autofillForms" into the search box and double-click the "signon.autofillForms" preference to set it to "false". Firefox will no longer autofill usernames and passwords without your permission.
If you're using another password manager, you should open its preferences and disable the "autofill" or "automatically fill" selection to ensure your password manager won't leak your personal information.
Browser and password manager developers demand to rethink password managers to make them more secure. They shouldn't try to automatically fill your login data on every single spider web page you visit on a particular website. That's just request for problem. But, for now, you tin can disable autofill to brand yourself more secure.
