Experts have warned about the threat to personal data with duplicate passwords.

The use of outdated and repetitive passwords can pose a serious threat to users' personal data. This was reported to Izvestia on March 20 by specialists from the Roskachestvo Center for Digital Expertise.

Modern approaches to cybersecurity have changed: if a user uses a complex and unique password, as well as two-factor authentication, it is not necessary to change it too often. On average, the current password usage period is 6-8 months, however, if all security rules are followed, it can be extended.

According to experts, the main risk is not related to the age of the password, but to its reuse on different services. In the event of a data leak on one of the platforms, attackers gain access to several accounts at once. After that, social engineering methods are often used when scammers try to get additional confirmation codes.

Experts also stressed the importance of using two-factor authentication, which includes not only SMS codes, but also authenticator applications, push notifications, and biometrics. At the same time, services where such protection is not available are the most vulnerable.

"I do not advise you to believe websites that offer to check the password for leaks. There is a risk that hackers themselves collect user data. If you want to check, do it through browsers, they do not compare passwords themselves, but encrypted casts, and this is secure. The main rule of digital hygiene today is not the frequent change of passwords, but their uniqueness. One strong password that you don't use anywhere else will last for years. And 100 passwords written on a sticker glued to a monitor won't last a day," said Sergey Kuzmenko, head of the Roskachestvo Digital Expertise Center.

Roskachestvo recalled that a strong and unique password can protect accounts for years, while even a large number of passwords will not ensure security if they are reused or stored in an unsafe way.

In October last year, Boris Lopatin, MegaFon's senior expert on fraud investigation, gave advice on data protection in case of phone loss. According to him, the first step is to check the connection. If you cannot reach your number, and your loved ones say that "the subscriber is unavailable," you must immediately suspend room service. To do this, you can use your personal account on the operator's website or call the call center.
