Today, given that so much of our personal and professional workflows involve an account-based SaaS application, password managers have emerged as a productivity staple. Storing passwords in your browsers, built-in storage, and autofill engine is often the most common practice, but it is fraught with security risks.
Instead, password managers offer a purpose-built solution to the security challenges arising from SaaS app sprawl, too many accounts, and multiple privileged users inside a business network. StudiesOpens a new window reveal that 85% of people know that reusing the same password can be risky, but nearly 1 in 4 do it anyway. Indeed, it can be a hassle to generate a strong password for every account you create and keep track of, particularly when passwords have to be reset at regular intervals.
Password managers come in all shapes and sizes. There are open-source applications like KeePass, personal solutions that double up for business use, and enterprise-only providers like Secret Server. You could choose targeted tools from a company like Specops or go for an all-in-one security solution such as LastPass for Business. Before we consider these top password management solutions, here are some of the must-have features to look for, no matter which one you choose:
USP: A major USP of Zoho Vault is its reporting module. Its real-time audits keep an eye on ongoing user activity, including timestamps and IP addresses of IT admins themselves. You configure email notifications to admins and users in case of security events, and password sharing data is captured.
Password managers allow the storage and retrieval of sensitive information froman encrypted database. Users rely on them to provide better security guaranteesagainst trivial exfiltration than alternative ways of storing passwords, such asan unsecured flat text file. In this paper we propose security guaranteespassword managers should offer and examine the underlying workings of fivepopular password managers targeting the Windows 10 platform: 1Password 7 [1],1Password 4 [1], Dashlane [2], KeePass [3], and LastPass [4]. We anticipatedthat password managers would employ basic security best practices, such asscrubbing secrets from memory when they are not in use and sanitization ofmemory once a password manager was logged out and placed into a locked state.However, we found that in all password managers we examined, trivial secretsextraction was possible from a locked password manager, including the masterpassword in some cases, exposing up to 60 million users that use the passwordmanagers in this study to secrets retrieval from an assumed secure lockedstate.
An example in which a password manager appears to have been specifically targeted isan attack that led to the loss of 2578 units of Ethereum (ETH), a cryptocurrencyvalued at the time of 1.5 million USD. The attack was carried out against acryptocurrency trading assistant platform, Taylor [12]. Taylor issued a statementthat indicated a device which was using 1Password for secrets management wascompromised [13]. It remains unclear, whether the attacker found a security issue in1Password itself or simply discovered the master password in some other way, orwhether the compromise had nothing to do with password managers.
Given the combination of an increasing number of credentials held in passwordmanagers, the value of those secrets and the emerging threats specifically targetingpassword managers it is important for us to examine the increased risk a user ororganization faces in terms of secrets exposure when using a password manager. Ourapproach for this was to survey popular password managers to determine commondefenses they employ against secrets exfiltration. We incorporate the best securityfeatures of each into a hypothetical, best possible password manager, that providesa minimum set of guarantees outlined in the next section. Then we compare thepassword managers studied against those security guarantees.
All password managers studied work in the same basic way. Users enter or generatepasswords in the software and add any pertinent metadata (e.g., answers to securityquestions, and the site the password goes to). This information is encrypted andthen decrypted only when it is needed for display, for passing to a browser add-onthat fills the password into a website, or for copying to the clipboard foruse.
In addition to these explicit security guarantees, we expect password managers toincorporate additional hardening measures where possible, and to have thesehardening measures enabled by default. For example, password managers should attemptto block software keystroke loggers from accessing the master password as it istyped, attempt to limit the exposure of unencrypted passwords left on the clipboard,and take reasonable steps to detect and block modification or patching of thepassword manager and its supporting libraries that might expose passwords.
We expected and found that all password managers reviewed sufficiently protect themaster password and individual passwords while they are notrunning. Theremaining bulk of our assessment of password managers in the running state wasfocused on the effectiveness of the locked state and whether the unlocked state leftthe minimum possible amount of sensitive information in memory. The followingsections outline violations of our proposed security guarantees of password managersin a running locked and unlocked state.
We assessed the security of 1Password4 while running and found reasonable protectionsagainst exposure of individual passwords in the unlocked state; unfortunately, thiswas overshadowed by its handling of the master password and several brokenimplementation details when transitioning from the unlocked to the locked state. Onthe positive side, we found that as a user accesses different entries in 1Password4,the software is careful to clear the previous unencrypted password from memorybefore loading another. This means that only one unencrypted password can be inmemory at once. On the negative side, the master password remains in memory whenunlocked (albeit in obfuscated form) and the software fails to scrub the obfuscatedpassword memory region sufficiently when transitioning from the unlocked to thelocked state. We also found a bug where, under certain user actions, the masterpassword can be left in memory in cleartext even while locked.
Studies have shown that the majority of people use very weak passwords and reuse them on different websites. In fact, nearly 35% are using the same password for most of their online logins. The best password managers are the ones which are easy to use and let you manage all your online passwords in a protected and easier way.
Bitwarden is one of the best free password managers. It's available across iOS and Android. It also has native desktop applications on Windows, macOS, and Linux. It also integrates with every major browser including Chrome, Safari, Firefox, and Edge.
Because your passwords are securely stored, password managers make it easier to maintain secure, unique passwords. For instance, instead of using a simple, easy-to-remember password for all your accounts, you can use your password manager to store complex passwords (like Gn$3kj$g34s) that are unique to your every account. Not only will those passwords be much harder to guess, their uniqueness is an additional security measure. When you reuse passwords, every account that uses the same password becomes vulnerable if one account is compromised.
Some password managers are free, but more feature-rich services tend to charge a monthly subscription fee.What Are the Pros and Cons of a Password Manager?A password manager can help you achieve online security, but they do come with some drawbacks. Here are some of the pros and cons of using a password manager.ProsPasswords are remembered for you. A password-protected vault of passwords simplifies access to websites that require logins. Memorizing one master password is easier than memorizing a few passwords or, worse yet, dozens of passwords. According to the Google survey, 36% of people surveyed said they keep track of their passwords by writing them on a piece of paper.Passwords can be unique and complex. If your password manager automatically generates a hard-to-guess password for each site you visit, it can prevent you from repeatedly using simple-to-guess passwords. The most commonly used passwords are easy to figure out: 123456, Password and abc123. A secure password, however, will feature at least 12 random characters, including numbers, uppercase letters, lowercase letters and symbols.Passwords are encrypted. Password managers protect the data they store through what's known as encryption. This process scrambles data so that it's tougher for hackers, cybercrooks and others to access your personal information, such as Social Security numbers and credit card numbers. Compared with storing your passwords on a piece of paper in your desk or in a digital file stored on your laptop, encryption with a password manager is akin to locking passwords up in a bank vault.ConsThere's still some vulnerability to consider. If a hacker or someone else somehow learns the master password for your password manager, the master password and all of the other passwords stored there could be stolen.You might forget your master password. Many of us forget passwords from time to time. But what happens if you forget the all-important master password? Typically, you'll be locked out of the password manager's database. There are ways to get back in, but the worst-case scenario is that you'll then be forced to reset the password for every account included in your "vault." To avoid this nightmare, make sure you commit your password to memory. You could even write down your password and keep it in a real-world safety deposit box.Setup and use could be difficult. Setting up a password manager can be tedious. You may be able to import passwords stored in your browser or elsewhere to populate the database, but you might have to do much of it manually by entering the username and password for every account you want in the password manager. Using a password manager can also be hit and miss, as autofill features might not work well with every website and you may have to type in complex passwords manually, which isn't fun.Are Password Managers Really Safe?Online security experts generally recommend a password manager as the best method for keeping all of your passwords safe. While password managers defend against unwelcome visitors by encrypting data, they may themselves be vulnerable to cyberintruders. When you use a password manager, you'll need to have some faith that the company behind the technology isn't cutting any corners with the security of your data. Even with these risks in mind, password managers are still a smart alternative to juggling dozens of passwords in your head or writing them on sticky notes.What Are the Top Password Managers?If you're committed to using a password manager, how do you decide which one to pick? Here are five highly rated options that might be right for you. Most of the services below come with basic free versions and subscription versions that have more features, but the free versions are good enough for most users. 2b1af7f3a8
