Do you think password managers are safe? You probably do, or at least hope they are if you are using them. Keep in mind, there is no such thing as 100% safe or 100% secure. Password managers, the companies that create, host, and deploy them, have one job and that is to keep your passwords secure. From my experience, they’ve done a pretty good job of that thus far.
Benefits of using a Password Manager
To this day I am unaware of a password manager that has been breached in such a way where all of the user data was unencrypted and exposed. In general, these companies engage in full on application security and have bank level or military grade encryption. What is so bizarre to me is last I read, less than 10% of computer users use a password manager. I think a password manager is the best use of my time and money in regards to computer security.
If a password manager was to get hacked, the path of least resistance would be targeting an individual user, compromising their device, and logging into their password manager itself.
Although researchers had shown that they might not be as safe as you think they are. Before we go further, though, just know that I’m not too worried about this.
Password Managers’ Safety
First, let’s take a look at this study. Generally, it looked at how often passwords were leaking from host computers, and then focused on if the password managers that were installed were leaving passwords on the memory of the computers.
What the study found was that all of the password managers did a good job at keeping passwords safe when it was “not running.” So, it means that a hacker wouldn’t be able to force the software into giving away a password. However, it also found that all of the password managers that were tested made an attempt to remove the password from the memory of the computer…but in a couple of cases, the passwords were still found.
Some of the software tested, left the master password and the secret key on the computer. What this means is that it could be possible now for a hacker to access information from the program. But, you have to realize that these programs are trying to remove the information…but due to situational incidents, it isn’t always possible.
Another software that was tested, caused some concerns with the researchers. Essentially, the program takes passwords when the user types them, and scrambles them, but they are decrypted when put into the computer’s memory.
Yet another password manager was examined. Here, the software removed the master password from the memory of the computer, and it was not able to be found.
Is this something to worry about? It depends. How a password manager behaves on a device and whether or not it stores entered password in memory etc. shouldn’t be that big of a deal. In reality, if the device has spyware on it, or a malware that allows for full recording of every keystroke, then that device in that user is essentially screwed.
What if the password manager gets hacked?
Since researchers had pointed out these issues, all of the programs had been updated and changed. That’s why I’m not worried. Plus, the real issue doesn’t have much to do with the password managers’ security in regards to its memory or cloud access or its application security, but with the security of the devices that they are on.
In every security awareness training I do, I expound upon the benefits of using a password manager. Inevitably, in every discussion, the question comes up “what if the password manager gets hacked?” The pure naïveté of that question comes from most computer users belief that hacking or penetrating hardware software or networks etc. is as easy as snapping one’s fingers. It is not. There are generally a number of scenarios that need to come together in order for a device to be compromised.
But there is one single solitary scenario that makes data on a device vulnerable and that is “password re-use” leading to credential stuffing. Credential stuffing is such a weird term. Anyways, OWASP defines Credential stuffing as “the automated injection of stolen username and password pairs (“credentials”) in to website login forms, in order to fraudulently gain access to user accounts. Since many users will re-use the same password and username/email, when those credentials are exposed (by a database breach or phishing attack, for example) submitting those sets of stolen credentials into dozens or hundreds of other sites can allow an attacker to compromise those accounts too.”
Check your password
When you look at the danger of using one password over and over again, you are much safer when using a password manager. Meanwhile head over to my website homepage and scroll down until you see our Password Checker and click “Check if your password has been breached”. Don’t worry about entering your password on the site. We don’t store anything and what can we possibly do with the password? It’s just a password. How can we possibly track that back to any specific account? At a minimum we would need an additional user name. If you’re so concerned, do it from a private browser and or use VPN. It just doesn’t matter. Relax. Just get a password manager.
