Most security breaches happen because of poor passwords and "Donald," the U.S. President's first name, makes a weak choice.

Trump's first name is apparently one of the most commonly used but worst passwords of 2018. It occupies the 23rd spot in the latest list of the Top 100 worst passwords revealed by SplashData.

"Sorry, Mr. President, but this is not fake news-using your name or any common name as a password is a dangerous decision," said Morgan Slain, the security software company's CEO, in a statement.

Why People Mostly Used Weak Passwords

Slain explained that people prefer to use passwords that are easy to remember. These include the names of celebrities, terminologies used in pop culture and sports, or simple keyboard patterns.

Because of these poor choices of passwords, hackers get a higher possibility of breaking into online accounts, allowing them to steal user information.

'123456' At The No. 1 Spot In 5 Years

On top of this year's most terrible passwords are "123456789", "password," and "123456." This year marks the 5th consecutive year that these have topped the list of the worst passwords people used to lock their accounts.

SplashData gathered the list from over 5 million leaked passwords to determine which of these are most commonly used by people. It estimates that 10 percent of the online users have used at least one of the top 25 worst passwords in this year's list. About 3 percent of them were using "123456" as their password.

Slain said they hope that by releasing the top 100 worst passwords every year, people will be persuaded enough to take steps to protect themselves online.

"It's a real head-scratcher that with all the risks known, and with so many highly publicized hacks such as Marriott and the National Republican Congressional Committee, that people continue putting themselves at such risk year-after-year," he said.
