How secure your password is depends on three simple factors. The most important factor is the length of your password. The second most important factor to make sure your password is strong is that the password must not consist of patterns. Patterns that someone could figure out based on things they may already know about you or that they can discover about you. In order to make your password secure you need to make passwords that contain as many characters as allowed by the web site or app for which you are creating the password. The third most important factor in securing your password is how often you reuse your password. Once is more than enough.
Ideally a password should only be used once. The more often you reuse a password, the more likely that password will become exposed in a data breach. Once that password has been exposed, the hackers can try that same password on other common websites. If you have used it more than once there is a good chance that one site being hacked could cause all of your social media accounts, or banking logins to be compromised.
Follow these rules and best practices for better memorable passwords
Have long, strong passwords. Use a mixture of numbers, letters, and special characters
Do not reuse passwords across multiple sites
Store passwords securely – use a password manager. It will do the hard work for you
Use two-factor authentication - something you have. The second factor prevents password guessing
If a site you use falls to a data breach, change your password immediately. Make sure you are not re-using that password and email combination on other sites
The strength of the password of a given length is strongly defined by the variety of characters and symbols in the word. Using a random password generator can help with unique passwords. Protect every account you create by generating complex, randomized passwords. Do not reuse it for more than one log in or account. Ever.
