Over 19 billion passwords were leaked in the security crisis. Here you will find whether you are vulnerable

Last year alone, over 19 billion passwords among the experts were leaked as “crisis” as “cyber security”.

But there are ways to protect yourself.

A new study by Cybernews Between April 2024 and 2025, more than 200 data injuries were examined and found that 94 percent of the 19.030,305,929 newly exposed passwords were reused or duplicated – in some cases complete by different users.

“We are faced with a widespread epidemic of reuse of weak password” Cybernews. “Only 6 percent of the passwords are clear, so other users for dictionary attacks are very susceptible. For most, the security on the thread of the two-factor authentication-what is activated at all.”

Experts demanded an acceleration of stricter security methods to emphasize that cybercriminals only need a free -reading password in order to then access e -mail addresses and other personal data.

The leaks examined by researchers were “loaded with information with which accounts steal or affected people with identity theft attacks,” said the study.

The study showed that millions still prefer basic passwords that can easily remember – and easily advise for hackers. “Password” is used by 56 million people and 53 million use “admin”.

The researchers also found that “1234” makes up almost 4 percent of all passwords, which is easy for hackers.

The names of the people were the second most popular choice for a password.

“Many users choose a name as part of their password. We have linked the data record with the 100 most popular names of 2025 and found that they have a full 8 percent chance that they will be taken as part of a password,” said Macijauskaite.

Others opted for positive words such as “love”, which were used in 87 million passwords analyzed and “sun” in 34 million. Swear words are also common in the passwords, as research corresponds.

“Passwords created from profane or insulting words seem to be rare, but they are actually very common in practice,” said Macijauskaite. “Passwords that contain obscenities often come from attempts to personalize or memority. However, such terms are widespread among attackers Wordlists and are a significant risk of accounting security.”

Use password managers to create and save clear passwords for different accounts.

Never use passwords again.

Make sure that your password is at least 12 characters and contains large and small letters, numbers and at least one special symbol.

Activate the multi-factor authentication if possible, which reduces the risk, even if passwords are leaked or hacked.

Check the access controls regularly and carry out regular security audits. Monitor and react to login information.
