An attempt to hack into a system can be thrashed if the system is guarded with a strong backdoor password. But, what makes a password so strong that it can reduce the risk of online security breaches so effectively? If you’ve been wondering the same, then the guide below is your go-to list for all password related answers.
- Length is Strength
A short password that’s flat and simple is weak. The minimum number of acceptable characters are 8. However, a password that contains 12-20 characters is deemed strong. Therefore, remember to make the backdoor password of your IoT devices long.
- Uniqueness is Essential
Let’s just say, a password that’s 12 characters long but contains only letters with no other variation will actually be weaker than 8 characters long password that contains a mixture of uppercase and lowercase letters, numbers, and unique symbols. Therefore, make long passwords unique.
- Complexity Matters
A long and unique password becomes highly unpredictable when simple words are further complicated. For example, the word ‘bat’ can be modified in a number of ways like;
These are a few examples only. You can always get creative and make the passwords complex.
Now, apart from these 3 ways to create a password, there are also certain ground rules that are necessary in order to ensure that the strong password remains safe for use. The guide to this safety is listed below.
- Avoid Reusing The Passwords
Do not reuse a password, we hear that too often, but how? Since a single user has multiple IoT devices and social media accounts, how is it possible to remember so many new passwords? Well, the simple solution is using a password management app.
A password managing app is an encrypted software that can be used to virtually save all your passwords. The best thing about using such apps is that you have to remember the password of the app only. And that’s how you can avoid reusing old passwords.
- Avoid Repeating Passwords
Whilst reusing usually includes using an old password that you no longer use to safeguard a new device, repeating a password, on the other hand, is simply using one password for all/many devices and accounts. This is one risky habit. If hackers can decode a password and you are using the same for multiple devices, then all those devices will become vulnerable at once. So, use a different password for every single IoT device.
