Game, which is played in advance

Saving passwords in the browser’s memory, you should consider:any

In order not to be unfounded, let’s give the floor to the expert. On the topic of storing details in the browser, spoke out perfectlyJustin Shuch

In one of the discussions on the Internet resourceHacker News

'Imagine, that an attacker has gained access to your computer account. It can copy all saved sessions and the entire log of your browser, install any plugins and extensions to intercept all your Internet traffic and even stuff your operating system with Trojans and hidden monitoring programs.I think, that the game is already lost at that moment, when an attacker gained access to your computer under your account. Further resistance is just pointless, he's got all the trump cards.'

Therefore, Google Chrome uses only the means of the operating system to protect confidential data - that is,, means of protectingthe entire user account

Because any person, who gained access to the computer (that is, to your ‘account’ in the operating system), will be able to do absolutely everything, what you can do, including logging in on your behalf to different sites. Moreover, it can be not only an abstract hacker from the Internet, but also, eg, your close friend or colleague.

Save passwords - don’t let anyone near them!

When attempting a malware injection attack via the browser, he will be met by your antivirus and Windows Defender, an antivirus application for Android or a closed iOS ecosystem.

A much greater danger is provided by the simplest scenario - the people next to you. Should you take a short break from the computer at work, leaving it on, and a malicious colleague can arrange a corporate email newsletter from your PC or copy some data, representing a trade secret.

It’s the same with the household: no one will prevent your brother from copying all your passwords from the browser, as soon as you step away from the laptop, to make fun of you later. Or your wife - go to your favorite social network and make a scandal, after seeing your correspondence with your ex. Or a child can get into an online bank and transfer money from your card to an electronic wallet, to pay for a purchase in an online game.

Therefore, there can be only one conclusion here: if you want to store confidential information in the browser, keep it, but don’t let anyone near her! A few tips, how to do this, we’ll give it now.

Expert comment

Denis legezo, Kaspersky Lab antivirus expert.
‘Save email passwords, It is not safe to use social networks or online banking in browsers. Yes, in modern browsers, you can set a master password to encrypt saved data, but directories, in which browsers store such information, in any case, they are known. How are the pests also known, which such files are taken away. In combination with the threat from keyloggers, storing passwords in the browser becomes even more dangerous.
Ideally, it is better to enter your username and password every time, when you log in to your billing accounts, social media pages or email. The safest option for storing passwords is still in the head. The disadvantage of this approach is that, that passwords must be unique for different services, and it’s not easy to remember a large number of complex passwords.
Convenient and more secure, than saving in browsers, It is an option to store passwords in a specially designed local password manager program. In this case, the user shares the active in the network, and therefore a browser at risk, and your encrypted password database.’
