How to Generate Strong Passwords - Security Guide

What Makes a Password Strong?

A strong password is one that is difficult for both humans and computers to guess. The strength of a password depends on its length, complexity, and unpredictability. A 12-character random password with mixed case, numbers, and symbols would take billions of years to crack with current computing power.

Password Strength Factors

• Length — The most important factor. Each additional character exponentially increases the number of possible combinations. Aim for at least 14 characters.
• Character variety — Use uppercase letters, lowercase letters, numbers, and special symbols to maximize the keyspace.
• Randomness — Avoid dictionary words, names, dates, and keyboard patterns like qwerty or 123456.
• Uniqueness — Never reuse passwords across accounts. A breach on one site should not compromise all your accounts.

Common Password Mistakes

Using personal information such as birthdays, pet names, or phone numbers makes passwords easy to guess via social engineering. Simple substitutions like p@ssw0rd are also well-known to attackers and offer little real protection.

Password Management Tips

• Use a password manager to store and auto-fill unique passwords for every site.
• Enable two-factor authentication (2FA) wherever available for an extra layer of security.
• Change passwords immediately if a service you use reports a data breach.
• Consider using passphrases — random word combinations like "correct horse battery staple" are both strong and memorable.
