Hidden Danger Behind Save Browser Password

– Saving the password in the browser does feel very practical. You don’t have to bother remembering or retyping your password every time you want to login to your favorite site. Just save once, the browser will automatically fill in the login field for you. Not surprisingly, many people are used to relying on this feature to facilitate their daily digital activities.
However, behind that practicality, there is a risk that is often overlooked. The habit of storing passwords in the browser can actually become a security hole that is used by irresponsible parties. Important data such as social media accounts, e-mails, to banking services can be vulnerable to being hacked if your device falls into the wrong hands or is infiltrated by malware. Before you continue to rely on this feature, it is worth understanding the hidden dangers behind it.
browser security vulnerability
Browser is a very complex software and is constantly connected to the internet at all times. Because of its nature, the browser is often the target of cybercriminal attacks who are looking for security vulnerabilities (vulnerability). If this gap is found, criminals can steal all the login data you store in your browser without you knowing it. Although regular updates usually fix this problem, there is always the risk of new gaps that have not been closed. Thus, storing a password in the browser means that you are also risking data security at the browser security level itself.
synchronization between devices
Many browsers now have an inter-device sync feature that allows passwords to be automatically saved on all the devices you use. This feature is indeed practical because you only need to login once to be able to access accounts on cellphones, laptops, and tablets. However, this is also a weak point if one of your devices is hacked or lost. Cyber criminals can take advantage of synced devices to steal all your accounts at once. So, synchronization can be a double-edged sword for security.
physical access
One of the most obvious risks is if someone directly holds or borrows your laptop or cell phone. Many people forget that the browser does not always ask for additional verification when opening a list of saved passwords. This means that anyone who has physical access to your device can easily view and record all usernames and passwords. Even in some cases, it only takes a few clicks to export the entire password list. This is why it is very dangerous to store passwords on devices that are often used together.
Limited security features
The browser default password manager usually does not have a security feature as complex as a special application. For example, a two-factor (2FA) authentication feature or high-level encryption is usually not available in the browser. Though, these features are important to ensure passwords are protected even if someone successfully logs into your account or device. In addition, the browser generally does not give you the option to audit the strength of the password or warn if the password is already leaked. This makes the security of your password much weaker than using a professional password manager.
Third party service risk
Some browsers use third-party servers to store and sync your data. If the server is hacked or data leakage, your entire account list and password can be exposed. Cases of data leakage like this have occurred several times in major services, which causes big losses for users.
Phishing
The autofill browser feature often helps you log in faster without having to type anything. Unfortunately, this feature can backfire when you accidentally open a fake site that imitates the appearance of the original site. The browser will automatically fill in your username and password on the page, making it easier for thieves to record your login data. This is a modern phishing technique that is increasingly being used to trap careless users. Therefore, relying too much on autofill actually increases the risk of data theft.
Those are some of the hidden dangers behind the habit of storing passwords in the browser. Hopefully useful.
