The 20 Most Common Passwords: Mistakes You Should Avoid

Every year, studies are published on the most used passwords in the world, and the results are alarming: millions of people continue to use passwords that an attacker could guess in less than a second. If any of your passwords appear on this list, you are exposed to serious risk. Let's see what they are, why they are so dangerous and how to fix it immediately.

The 20 most used (and most vulnerable) passwords

Based on the most recent data breaches analyzed by cybersecurity companies such as NordPass and SplashData, this is the updated list of the most common passwords. If you recognize one as yours, change it right now using our strong password generator.

The patterns used by attackers

Cybercriminals do not test passwords at random. They use sophisticated algorithms that know the most common human patterns:

• Keyboard sequences: qwerty, asdfgh, zxcvbn and their variants with numbers.
• Number sequences: 123456, 111111, 000000 and similar.
• Common words + numbers: password1, admin123, love2026.
• Proper nouns: Names of pets, couples, children or football teams, easily searchable on social networks.
• Predictable substitutions: p@ssw0rd, l3tm31n, @dmin. Attackers know all of these variants and test them automatically.
• Important dates: Birthdays, anniversaries, graduation years. If you post your birthday on Facebook, this information is public.

How to know if your password has been leaked

Services like HaveIBeenPwned maintain databases of billions of leaked credentials. You can enter your email to find out if any of your accounts have been compromised in a known breach. If you appear in one, immediately change the password of that service and any other where you use the same password.

Many modern password managers include this verification built in, automatically alerting you when they detect that one of your passwords has appeared in a public leak. To learn more about how to protect yourself, read our digital security in 2026.

The solution: generate random passwords

The best password is one that you can't remember because it is completely random. A sequence like "k7$Qm!x9Lp@2wR&z" does not follow any predictable human pattern and would take billions of years to decipher by brute force. The key is to use a password manager that remembers it for you.
