The most common password mistakes are reusing the same password across multiple sites, using weak, easily guessable passwords (like "123456", "password", or personal info), making them too short (under 12-16 chars), and not using multi-factor authentication (MFA), which makes accounts highly vulnerable to breaches, especially credential stuffing attacks.
5 common mistakes in password security
A Password is a word, phrase, or string of characters intended to differentiate an authorized user or process, for the purpose of permitting access (such as via logging in) from an unauthorized user. Defined another way, a password is used to prove one's identity, or authorize access to a resource.
8675309 is a famously common 7-digit password due to the popular 1980s song "867-5309/Jenny" by Tommy Tutone, making it highly guessable and a security risk. It's often ranking among the most used 7-digit passwords alongside sequences like 1234567.
Many of the stolen passwords were embarrassingly simple. Variations of “password123,” “123456,” and “linkedin” (creative, right?) were found everywhere. This breach wasn't just an inconvenience—it was a gateway for hackers to access other accounts, since many users reused the same password across multiple platforms.
The Least Common PINs
According to the same data, the least commonly used 4-digit PIN is 8068, with just 25 occurrences out of the 3.4 million passwords examined — a minuscule 0.000744% frequency . The 10 least popular 4-digit PINs found in the study's dataset, starting with the least common, are: 8068. 8093.
Simple passwords, such as 12345, or common identifying information, like birthdays and pet names, are not safe for protecting important accounts holding personal information. Using an easy-to-guess password is like locking the door but leaving the key in the lock.
Because our normal number base is 10, so that is all we need. These symbols, known as “Arabic numerals” were adopted from India and the Middle East to replace the Roman numeral system, IVXLCDM, which was non-positional, lacked zero, and had only 7 numeral symbols borrowed from the alphabet.
Cisco password type 0 is basically clear text password. There is no encryption nor obfuscation. It is the oldest and the most insecure method of storing passwords in Cisco devices. It should never be used.
Make your master password long and complex—don't use “qwerty”. Password managers with browser extensions can help deter phishing. Your password manager will object to entering a password into the wrong website, no matter how convincing it looks.
In 1961, MIT computer science professor Fernando Corbato created the first digital password as a project problem-solver. When he built a giant time-sharing computer, several users needed their own private access to the terminals.
If you see yours here, it's time for an immediate change!
Human brains were responsible for choosing passwords like "123456", "password," and "qwerty." But there is no way that 91,103 people independently chose to secure their accounts with "18atcskd2w." Instead, what I believe happened is that these accounts were created by bots, perhaps with the intention of posting spam ...
The most common malicious code examples out there include computer viruses, Trojan horses, worms, bots, spyware, ransomware, and logic bombs.
Stay away from simple, easily guessable PINs like "1234," "0000," "1111," "123456," or "9876." Don't use personal information such as birthdates, anniversaries, phone numbers, or other details that someone could easily guess.
1Password is SOC 2 type 2 certified and complies with the most stringent industry standards for data confidentiality, integrity, and availability.
They also prefer numbers that are easy to type, like the figure “2580” which goes straight down the numberpad. Other predictable numbers stem from the fact that we use birthdays and birth-years so we can easily remember the PIN code.
Make sure you use at least 12 characters. Use a combo of uppercase letters, lowercase letters, numbers, and even some special characters (!, @, $, %, ^, &, *, +, #) in ALL passwords.
After analyzing the dataset, he reported his findings: The 'Best' (least commonly used) PIN: "In my dataset the answer is 8068 with just 25 occurrences in 3.4 million (this equates to 0.000744%, far, far fewer than random distribution would predict, and five orders of magnitude behind the most popular choice)."
A strong password is:
During one study she conducted, Cranor actually asked participants who chose the primate to explain why they picked it. "Basically people said they like monkeys, monkeys are cute," says Cranor. "Some people said they had a pet named monkey, they had a friend whose nickname was monkey, it was all very positive."
