How to Create a Strong Password and Keep Your Accounts Safe

Why length beats complexity, how password managers work and why two-factor authentication matters.

Weak or reused passwords are the most common reason accounts get taken over. The good news is that a solid password routine is easy to set up.

Length beats complexity

How long a password takes to guess depends mostly on its length. Each extra character multiplies the number of combinations an attacker must try. Aim for at least 12–16 characters. A short password that looks complicated, like “Aa1!”, is far easier to crack than a long random one.

Why random?

People choose predictable passwords: birth years, pet names, a word followed by “123”. Attackers try those patterns first. A randomly generated password does not follow any pattern. Our generator uses your browser’s secure random number source and never sends the password anywhere.

A different password for every site

When one site leaks its database, attackers try your password elsewhere. Use a unique password per account. Since you cannot memorise them all, use a password manager and remember just one strong master password.

Turn on two-factor authentication

Even if a password is stolen, a second step such as an app code or security key protects the account. Enable it for email, banking and social media. SMS codes are better than nothing, but app-based codes are safer.

What to avoid

  • Personal details such as names, birthdays or phone numbers
  • Keyboard patterns (qwerty, 12345678)
  • Reusing a password with tiny variations
  • Storing passwords in a notes file or chat app
