That's how long it takes a hacker to crack your password

How secure is my email password? How quickly can my app account be cracked? And how long does it take a hacker to crack my iCloud password? Some tools on the internet aim to provide answers to these questions. However, one can wonder how useful it is to enter one's own (actually secret) passwords in a web tool. Therefore, in addition to the links to a few of the password checkers, this guide also gives you one or two tips on how to use them. So your passwords stay secret, and you still know how safe they are;)

How long does it take a hacker to crack my password? How quickly can the password be cracked by a brute force attack? Here you can find out.

How secure is my password?

How secure the password is for the email account, for an app or for the iCloud, you can theoretically determine with an infographic. There are, among other things at Hive Systems or in the following as a picture. From this you can see that the most secure passwords are long, contain upper and lower case letters, have numbers and also have special characters (&,%, $, #, + or the like). A password is really safe if it has a green background in the infographic, i.e. only 13 characters or more. Purple and red highlighted cells in the table mean that the password can be cracked very quickly.



How fast can a hacker crack my password?

In addition to the overview, which tells you how many letters, numbers and special characters you should use, there are also web tools with text fields in which you can enter your passwords. They are then checked in real time, so that you can see directly how quickly a hacker can crack the password - not just by trying it out, but with a brute force attack (see below). A tip: if the original password STEVE & apple941 type something like HELGA§846micro instead. So you use the same length and number of uppercase letters, lowercase letters, special characters and numbers, but you change the order and the characters themselves.

What is a brute force attack?

"Brute Force" means something like "Brute Force". The hacking method so named is based on trying as many password options as possible in as little time as possible. First of all, of course, individual letters, letter-number combinations and frequently used words are used. A long password that only consists of a word and a series of numbers (for example "Password12345") is not as secure as a string of the same length that is more complex and randomized (for example "1PW2 # + 34apfel").

    Thanks, very insightful article! I came across this because my sister was spreading panic that someone might want to hack into our wireless repeater (from Fritzbox). She assigned a very simple password so that our mother wouldn't have trouble dialing in: five lower-case letters in a row, followed by 3 digits. Now it's true that this password could be hacked in 1 minute. But: Wouldn't the box fail anyway in the event of such an attack? Besides, is there any use at all for an attacker to dial into a home wireless repeater? I would be very grateful for an answer, as this topic has caused a huge row with us - although I already asked myself why she gives out such a cheap password at all if she thinks that it is so dangerous. Best regards, Claus

      Hello Claus! So in advance: I'm not a security researcher and I only have a mediocre idea. But I'll still try to answer your questions: If you want to crack the WLAN password, you can - as far as I know - work with the FritzBox using BruteForce. So simply put on a program that constantly tries new attempts with new combinations. But the answer that shows whether the password was right or wrong always takes a second. So you would have to bring a bit of time with you if you wanted to try it on the off chance.
      While you're making your attempts, you won't notice any difference on the FritzBox. It would simply continue to function... so the box does not fail. What would the attacker get out of it? Well, he could keep trying to get onto the connected computers. But that's more complex than cracking the WiFi password. Otherwise, he could simply use your IP address to send spam mail, distribute malware or send phishing mails. But I think there are so many open WLANs without a password that only someone who is specifically interested in your data will want to hack into your network. Ah, I forgot one more thing! With a tool like Wireshark you can also record the WLAN data traffic if you are in a foreign WLAN. You might be able to find out passwords and logins to other services via this. But honestly: You can do that with any other WLAN. I hope I was able to help you! LG, Jens

    Hi Jens,
    Many thanks for your detailed and quick answer! Helped a lot to calm everyone down. Best regards Claus

      It's a good thing they don't know WHO answered, otherwise they wouldn't be so reassured. 😊 I actually have no clue about the matter. 😂
