Secure your own passwords .

Hi,

Have you ever tried to find out that how secure your password is ? If no, then it's time to !

I just calculated the combinations of my gmail password, which is 921,016,874,347,885,620,264,960,000,000.

Obiously I wouldn't share my password's digits..... but believe me that even a super computer working with unimaginably high speed will atleast take 4 months to find all the combinations and it just depend on luck that anyone could get my password combination in an hour or so...(The person will seriously be very lucky !) The trick used here is just Combinatorics.

So now, take your calculators and find out how difficult your password is ....

Do not forget to comment your password's combination. I would love to see it and remember the longer the password the larger the number, so it might get difficult to learn it, but not impossible.

Thank you if you read till the end. I hope you enjoyed it. If I get alot of comments with combinations, I will soon perform an experiment with all the numbers I got. So I need alot of numbers ;)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Welp...I am scared.....My password's combinations come out to be a mere 512,267,156,706,970,828,800...

That not bad ! It's cool, because you will definitely receive a message that someone tried to access your account.

Wait a sec.....access my account???!! how could someone do that without knowing the email ID??

@Aaghaz Mahajan – Haha, I am saying that Blackhat Hackers are clever and they can get your details if they want, not a big deal. They can get your ID very easily but cracking password may trouble them.

Can you show us how can you calculate the combinations of any password, @Nikola Alfredi?

It is the total arrangements of your password's digits, that is what hackers try to crack.

Nikola Alfredi - 4 months, 2 weeks ago

My longest password was 100 digits - 100! = 9.332622e+157 different combinations:

I don't how long but BetterBuys thinks $\infty$

@Nikola Alfredi

It is amazing..... were you able to memorize it ?
