Can Google Employees See My Saved Google Chrome Passwords?

         

Storing your passwords on your internet browser looks as if a good time saver, however are the passwords stable and inaccessible to others (even staff of the browser firm) when squirreled away?

Nowadays’s Query & Resolution session involves us courtesy of SuperUser—a subdivision of Stack Alternate, a group-pushed grouping of Q&A web pages.

The Query

SuperUser reader MMA is curious if Google staff have (or may have) get admission to to the passwords he shops in Google Chrome:

I take into account that we’re actually tempted to avoid wasting our passwords in Google Chrome. The probably merit is 2 fold,

  • You don’t want to (memorize and) enter these lengthy and cryptic passwords.
  • These are on hand at any place you might be whenever you log in to your Google account.

The final level sparked my doubt. For the reason that password is on hand any place, the storage should in some principal region, and this will have to be at Google.

Now, my easy query is, can a Google worker see my passwords?

Looking over the Web printed a couple of articles/messages.

There are many more (including this one at this site), mostly along the same line, points, counter-points, huge debates. I refrain from mentioning them here, simply carry a search if you want to find them.

Coming back to my original query, can a Google employee see my password? Since I can view the password using a simple button, definitely they can be unhashed (decrypted) even if encrypted. This is very different from the passwords saved in Unix-like OS’s where the saved password can never be seen in plain text.

They use a one-way encryption algorithm to encrypt your passwords. This encrypted password is then stored in the passwd or shadow file. When you attempt to login, the password you type in is encrypted again and compared with the entry in the file that stores your passwords. If they match, it must be the same password, and you are allowed access. Thus, a superuser can change my password, can block my account, but he can never see my password.

So are his concerns well founded or will a little insight dispel his worry?

The Answer

SuperUser contributor Zeel helps put his mind at ease:

Short answer: No*

Passwords stored on your local machine can be decrypted by Chrome, as long as your OS user account is logged in. And then you can view those in plain text. At first this seems horrible, but how did you think auto-fill worked? When that password field gets filled in, Chrome must insert the real password into the HTML form element – or else the page wouldn’t work right, and you could not submit the form. And if the connection to the website is not over HTTPS, the plain text is then sent over the internet. In other words, if chrome can’t get the plain text passwords, then they are totally useless. A one way hash is no good, because we need to use them.

Now the passwords are in fact encrypted, the only way to get them back to plain text is to have the decryption key. That key is your Google password, or a secondary key you can set up. When you sign into Chrome and sync the Google servers will transmit the encrypted passwords, settings, bookmarks, auto-fill, etc, to your local machine. Here Chrome will decrypt the information and be able to use it.

On Google’s end all that info is stored in its encrpyted state, and they do not have the key to decrypt it. Your account password is checked against a hash to log in to Google, and even if you let chrome remember it, that encrypted version is hidden in the same bundle as the other passwords, impossible to access. So an employee could probably grab a dump of the encrypted data, but it wouldn’t do them any good, since they would have no way to use it.*

So no, Google employees can not** access your passwords, since they are encrypted on their servers.

* However, do not forget that any system that can be accessed by an authorized user can be accessed by an unauthorized user. Some systems are easier to break than other, but none are fail-proof. . . That being said, I think I will trust Google and the millions they spend on security systems, over any other password storage solution. And heck, I’m a wimpy nerd, it would be easier to beat the passwords out of me than break Google’s encryption.

** I am also assuming that there isn’t a person who just happens to work for Google gaining access to your local machine. In that case you are screwed, but employment at Google isn’t actually a factor any more. Moral: Hit Win + L before leaving machine.

While we agree with zeel that it’s a pretty safe bet (as long as your computer is not compromised) that your passwords are in fact safe while stored in Chrome, we prefer to encrypt all our logins and passwords in a LastPass vault.
