Every internet router comes with a user name and password to gain access to its configuration pages. You don't want just anyone on the network being able to edit things like firewall settings or the WiFi password. Users are normally advised to change the password for security reasons but many still don't do that or even know it's advisable to.

Forgetting your own or the default router password is very common because you don't really need to access the router settings very often. However, it is quite troublesome when you don't know the router password because there are several important settings that could literally block you and others from accessing the network or internet completely.

The most obvious advice you'd find on the Internet is to simply reset the router back to the default configuration. That is not a foolproof method because you still need to know the default password. Here are some ways to access your router if you've forgotten or don't know the password.

Find The Default Router Username And Password

Many computer users don't bother changing the router username and password so it may still be set at the manufacturer or internet provider defaults. If you're pretty sure the router password hasn't been changed, there are a couple of things you can do.

1. Find The Router Password Online

A simple solution to try is searching for your router's default password online. Using a search engine will bring up something but an easier way is checking at an online database for router passwords. Here are three websites you can check.

• PortForward.com
• PCWinTech.com A-L | M-Z
• RouterPasswords.com

At the very least, you will need to know the manufacturer of the router or the name of the ISP if the router came from your service provider. Knowing the model is also helpful but not essential.

Between them, the three sites above list literally thousands of router models and their default passwords. The chances are very good that the branded model or ISP supplied model is listed on at least one.

2. Check The Router For the Default Password

If you have easy access to the router, simply looking at the bottom or back of it might show the default user name and password to get into the router.

Many routers will either have the password printed somewhere on them or a small removable plastic card which might also contain default WiFi login details on the other side.

3. Guess The Default Password

If you're unlucky enough that your router isn't listed on the databases above or there's nothing on the router itself, here are a few usernames:passwords that are very common. You can also try combinations between any of the below.

Admin Password Hack

Mac os skin for windows. admin:admin
admin:password
admin:1234
admin:[blank]
[blank]:admin
root:root
root:password

Many Netgear routers default to admin:password|1234, several Zyxel routers use a combination of [blank]|root|admin:1234, while D-Link routers often use admin:admin|[blank]. Virtually all TP-Link routers use the same combination of admin:admin.

Try To Crack The Router Password

This method will simply try to find the router password by making multiple attempts to log in to your router with different credentials each time. This may not work if your router has built in protection against multiple failed login attempts.

4. Router Password Kracker

Router Password Kracker from Security Xploded tries to recover the forgotten router password through a dictionary attack. This means it works based on a list of words found in a dictionary file. The program itself comes with a password list (passlist.txt) which contains just over 3,000 common or router related words.

Enter the IP address of the router, common addresses are 192.168.0.1 or 192.168.1.1. A drawback of this method is you have to know or have a good idea of what the user name is. If you have no idea, common names are root, admin, user, or even a blank user name.

The chance of this working is obviously quite slim if you have changed the password to something personal. At least this method is automated and much faster compared to manually trying passwords. We found that the program didn't work with our router. It could be because our router's landing page does not ask for a password. If yours is the same, it might not work either.

Download Router Password Kracker

5. Router Password Recovery

This is basically the same tool as Router Password Kracker but instead runs from the command line and doesn't have a graphical user interface. The syntax is:

RouterPasswordRecovery.exe -i ipaddress -u username -f passlist

Like above, you need to know the username of the router or you can narrow it down to just a few possible options. If you don't supply a username it will default to using admin.

Download Router Password Recovery

Note: A dictionary based option to crack a password is only as good as the list of words you are using. In addition to the words in the passlist.txt provided by Security Xploded, you can also add your own passwords to the list if you have some ideas. Be aware that all entries in the list are case sensitive.

Decrypt a Router Configuration File

Most routers allow you to export or save the current configuration settings to a backup file (usually .conf). If you have previously done that and have the backup file to hand, the changed password should be inside but it will be encrypted. Here's a couple of tools that can try to decrypt the router password.

6. RouterPassView

RouterPassView decrypts the encrypted passwords that are saved in the configuration file from your router. It supports about 30 different brands including names like Netgear, Linksys, D-Link, TP-Link, Edimax, ZTE, and several other generic types of router. Check the RouterPassView webpage for a full list.

If RouterPassView is able to decrypt the password in the router configuration file, the process is instant. It can also decrypt wireless passwords and internet login passwords stored in the configuration file. The tool itself is most likely to work if you have one of the routers in the supported list. However, you can still try if yours isn't listed. Our router isn't listed but we still got the login password.

Download RouterPassView

7. Router Password Decryptor

This is another tool by Security Xploded but it works similarly to RouterPassView whereby it tries to decrypt stored passwords in a router configuration file. The program officially supports Cisco, Juniper, DLink, and BSNL routers but there's also a Smart mode where it will try to decrypt any router's configuration file.

Browse for the config file or drop it onto the window. Select the router brand from the drop down menu or Smart Mode if the router is not one of the four listed. Then press Start Recovery. In addition to router login passwords, the program can also decrypt WiFi passwords and internet login/PPPoE passwords. Right clicking on a password will offer to copy it to the clipboard or you can export all data to an HTML report.

Download Router Password Decryptor

If All Else Fails…

If none of the options above work, you're probably left with the last option which is to reset the router back to its default settings.

8. Resetting The Router

Resetting the router back to factory settings will revert everything back to the defaults like when you first received it. This probably won't cause users with ISP supplied routers too much trouble as important settings will be pre-configured already. You might only need to change something like the WiFi password back to the preferred option.

To reset the router, there's normally a small button that is sometimes recessed with the word reset near it at the back.

Use a pin or bent paperclip to press the button and hold it for at least 10 seconds. Most routers will turn all lights on or flash the lights before rebooting so you know the reset is working. You will, of course, need to know the default username and password for your router to gain access (see the top of the article).

The disadvantage of resetting a router back to factory defaults is if you have lots of custom configuration settings. You might need to reconfigure everything such as internet connection itself, firewall settings, port forwarding, MAC address filtering, and etc. If the option is there, back up your settings next time!

The 'RouterPassView' did it for me. Good stuff

I recommend visiting the the site of the guy who authored RouterPassView: nirsoft.net

His name is Nir Sofer and I found his site when I was running a Novell network at a bank. Most of my help calls were in regard to forgotten Windows passwords.

The network ran seamlessly, by the way. I miss Novell and I really appreciate Linux.

Anyway, although Nirsoft had nothing for me at that time (1999?), I downloaded a few of his utilities to play with. Mail password crackers among other utilities that were effective but frivilous in my opinion.

I visited his site several times over the years and it was apparent that the guy was determined and prolific. When Windows 7 came out I was absolutely stunned at over the rights we were giving up when we hit 'I Agree'. I read what I was about to agree to as the OS informed me it was installing Skype, an Update I had no interest in. I was told that I would be giving up all my rights to the images and conversations that went thru Skype. The agreement would establish MS as a discrete partner.

So I looked at the words behind a few other ‘I Agree' buttons and found that Google, Adobe and just about every bit of software I was using included a share clause.

This is where NirSoft came through. There's not much any of us can do about the eyes and ears on our work but NirSoft's numerous utilities were invaluable in pulling back the curtain to reveal the who, what and where of our current state of privacy intrusion. They do it a lot of it in real time and as an added bonus, his utilities don't add bloat or call home. They are portable and they are lean.

I don't know anything about Nir other than he seems to have put a lot of time into his work and he's very generous with his product.

Just sayin'.

Hi Raymond . Thanks for the information.
This will definitely be of use and help at times of need.

I have a ZTE F660 router that doesn not have the web configuration tool. I want to reconfigure it to connect to multiple devices in a LAN but i can't.
I have reset it to default settings but even then am not able to ssh the router from my laptop.

Any help please?

It is a very common problem we all face often. hope I will be able to reset my router password if I forget it in future. first three steps are easy compared to the fourth one. if we can solve the problem using any one of the first three steps then it will be okay.

What is Password Cracking?

Password cracking is the process of attempting to gain Unauthorized access to restricted systems using common passwords or algorithms that guess passwords. In other words, it's an art of obtaining the correct password that gives access to a system protected by an authentication method.

Password cracking employs a number of techniques to achieve its goals. The cracking process can involve either comparing stored passwords against word list or use algorithms to generate passwords that match

In this Tutorial, we will introduce you to the common password cracking techniques and the countermeasures you can implement to protect systems against such attacks.

Topics covered in this tutorial

What is password strength?

Password strength is the measure of a password's efficiency to resist password cracking attacks. The strength of a password is determined by;

• Length: the number of characters the password contains.
• Complexity: does it use a combination of letters, numbers, and symbol?
• Unpredictability: is it something that can be guessed easily by an attacker?

Let's now look at a practical example. We will use three passwords namely

1. password

2. password1

3. #password1$

For this example, we will use the password strength indicator of Cpanel when creating passwords. The images below show the password strengths of each of the above-listed passwords.

Note: the password used is password the strength is 1, and it's very weak.

Note: the password used is password1 the strength is 28, and it's still weak.

Note: The password used is #password1$ the strength is 60 and it's strong.

The higher the strength number, better the password.

Let's suppose that we have to store our above passwords using md5 encryption. We will use an online md5 hash generator to convert our passwords into md5 hashes.

We will now use http://www.md5this.com/ to crack the above hashes. The images below show the password cracking results for the above passwords.

As you can see from the above results, we managed to crack the first and second passwords that had lower strength numbers. We didn't manage to crack the third password which was longer, complex and unpredictable. It had a higher strength number.

Password cracking techniques

There are a number of techniques that can be used to crack passwords. We will describe the most commonly used ones below;

• Dictionary attack– This method involves the use of a wordlist to compare against user passwords.
• Brute force attack– This method is similar to the dictionary attack. Brute force attacks use algorithms that combine alpha-numeric characters and symbols to come up with passwords for the attack. For example, a password of the value 'password' can also be tried as p@$$word using the brute force attack.
• Rainbow table attack– This method uses pre-computed hashes. Let's assume that we have a database which stores passwords as md5 hashes. We can create another database that has md5 hashes of commonly used passwords. We can then compare the password hash we have against the stored hashes in the database. If a match is found, then we have the password.
• Guess– As the name suggests, this method involves guessing. Passwords such as qwerty, password, admin, etc. are commonly used or set as default passwords. If they have not been changed or if the user is careless when selecting passwords, then they can be easily compromised.
• Spidering– Most organizations use passwords that contain company information. This information can be found on company websites, social media such as facebook, twitter, etc. Spidering gathers information from these sources to come up with word lists. The word list is then used to perform dictionary and brute force attacks.

Spidering sample dictionary attack wordlist

Password cracking tool

These are software programs that are used to crack user passwords. We already looked at a similar tool in the above example on password strengths. The website www.md5this.com uses a rainbow table to crack passwords. We will now look at some of the commonly used tools

John the Ripper

John the Ripper uses the command prompt to crack passwords. This makes it suitable for advanced users who are comfortable working with commands. It uses to wordlist to crack passwords. The program is free, but the word list has to be bought. It has free alternative word lists that you can use. Visit the product website https://www.openwall.com/john/ for more information and how to use it.

Cain & Abel

Cain & Abel runs on windows. It is used to recover passwords for user accounts, recovery of Microsoft Access passwords; networking sniffing, etc. Unlike John the Ripper, Cain & Abel uses a graphic user interface. It is very common among newbies and script kiddies because of its simplicity of use. Visit the product website https://www.softpedia.com/get/Security/Decrypting-Decoding/Cain-and-Abel.shtml for more information and how to use it.

Ophcrack

Ophcrack is a cross-platform Windows password cracker that uses rainbow tables to crack passwords. It runs on Windows, Linux and Mac OS. It also has a module for brute force attacks among other features. Visit the product website https://ophcrack.sourceforge.io/ for more information and how to use it.

Password Cracking Counter Measures

• An organization can use the following methods to reduce the chances of the passwords been cracked
• Avoid short and easily predicable passwords
• Avoid using passwords with predictable patterns such as 11552266.
• Passwords stored in the database must always be encrypted. For md5 encryptions, its better to salt the password hashes before storing them. Salting involves adding some word to the provided password before creating the hash.
• Most registration systems have password strength indicators, organizations must adopt policies that favor high password strength numbers.

Hacking Activity: Hack Now!

In this practical scenario, we are going to crack Windows account with a simple password. Windows uses NTLM hashes to encrypt passwords. We will use the NTLM cracker tool in Cain and Abel to do that.

Cain and Abel cracker can be used to crack passwords using;

• Dictionary attack
• Brute force
• Cryptanalysis

We will use the dictionary attack in this example. You will need to download the dictionary attack wordlist here 10k-Most-Common.zip

Admin Password Vista

For this demonstration, we have created an account called Accounts with the password qwerty on Windows 7.

Password cracking steps

• Open Cain and Abel, you will get the following main screen

• Make sure the cracker tab is selected as shown above
• Click on the Add button on the toolbar.

• The following dialog window will appear

• The local user accounts will be displayed as follows. Note the results shown will be of the user accounts on your local machine.

• Right click on the account you want to crack. For this tutorial, we will use Accounts as the user account.

• The following screen will appear

• Right click on the dictionary section and select Add to list menu as shown above
• Browse to the 10k most common.txt file that you just downloaded

• Click on start button
• If the user used a simple password like qwerty, then you should be able to get the following results.

• Note: the time taken to crack the password depends on the password strength, complexity and processing power of your machine.
• If the password is not cracked using a dictionary attack, you can try brute force or cryptanalysis attacks.
