Strong passwords are the best way to keep your information safe online. But what exactly does it mean to have a “strong password”? A strong password is one that is not easily guessed or hacked, which takes more work than you might think. Here are some best practices for keeping your passwords strong.
Longer passwords are stronger. Some security professionals recommend using 16 characters if possible, but that can get hard to remember. Generally, using 8-12 characters that contain a mix of capital letters, lowercase letters, numbers, and special characters is pretty strong. Remember that each character you add to your password makes it a full order of magnitude harder to crack – that’s a great reason to add one more number or letter!
Don’t use dictionary words. Many password-cracking tools are set up to run through lists of common words, so using a random password generator is better. And remember that “password” doesn’t mean you have to use a single word! A good way to get length and complexity in your passwords is by using a three or four-word phrase. You can add numbers and special characters into that and have a password that’s easily remembered but near impossible to guess.
Although it might seem a good idea, don’t base your passwords on names of family members or birthdates. These are fairly innocuous bits of information that anyone might pick up, and that would give them a way into your accounts.
Lastly, avoid clusters of numbers or special characters. A grouping of four numbers suggests a year; six numbers together imply a birthday. Anywhere numbers or symbols are grouped together makes it easier for your password to be hacked.
