WIFI PASSWORD MASTER is an app that lets you see all the information related to a WiFi network such as frequency, signal, and the mac. It also lets you generate random passwords based on different security protocols. This doesn't mean that the app lets you hack into a WiFi network or anything like that, though, of course.

Why changing the password on the router worked, or why it somehow stopped working overnight, is a puzzle to me. I did go through some firewall settings on my laptop, I was messing with Stream what you hear, but not sure how they could have effected things here?

What worked for me is disabling the 5 ghz network on my router (it has 2 antennas for 2.4ghz and 5ghz, both with the same ssid and password). After disabling it the Sonos box immediately accepted the password that it had rejected multiple times before.

The most frustrating part of the whole experience is that Sonos keeps telling you that the password you entered is wrong and doesn't offer any other option then to try again. And apparently there are quite a few things you can try to get it to work.

Having this issue with the Beam. Installed it and worked fine yesterday. I have tried troubleshooting - the Sonos has created its own network - but I get an error that says the wifi password is incorrect even though I can log into the same network with the password. Will give this a try! Thank you.

Had exactly the same issue. Repeated hard factory resets of my Sonos One (which had worked for a couple of years fault free then just dropped off the network) did not work. Went through the reset, add, password incorrect, connect to ethernet, device not found loop enough times to scream.

There is a workaround, but it does involve purchasing a $20 additional piece of hardware, a travel router. The travel router uses WISP protocol to allow you to log into the wifi provider on your computer or phone and then once authorized, the router bridges that signal to a separate wifi SSID which the camera can connect to.

In cryptanalysis and computer security, password cracking is the process of recovering passwords[1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.[2] Another type of approach is password spraying, which is often automated and occurs slowly over time in order to remain undetected, using a list of common passwords.[3]

The purpose of password cracking might be to help a user recover a forgotten password (due to the fact that installing an entirely new password would involve System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions restricted.

The time to crack a password is related to bit strength .mw-parser-output div.crossreference{padding-left:0}.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}(see Password cracking), which is a measure of the password's entropy, and the details of how the password is stored. Most methods of password cracking require the computer to produce many candidate passwords, each of which is checked. One example is brute-force cracking, in which a computer tries every possible key or password until it succeeds. With multiple processors, this time can be optimized through searching from the last possible group of symbols and the beginning at the same time, with other processors being placed to search through a designated selection of possible passwords.[4] More common methods of password cracking, such as dictionary attacks, pattern checking, word list substitution, etc. attempt to reduce the number of trials required and will usually be attempted before brute force. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover the password and reduces the likelihood that the password will be found in any cracking dictionary.[5]

The ability to crack passwords using computer programs is also a function of the number of possible passwords per second which can be checked. If a hash of the target password is available to the attacker, this number can be in the billions or trillions per second, since an offline attack is possible. If not, the rate depends on whether the authentication software limits how often a password can be tried, either by time delays, CAPTCHAs, or forced lockouts after some number of failed attempts. Another situation where quick guessing is possible is when the password is used to form a cryptographic key. In such cases, an attacker can quickly check to see if a guessed password successfully decodes encrypted data.

For some kinds of password hash, ordinary desktop computers can test over a hundred million passwords per second using password cracking tools running on a general purpose CPU and billions of passwords per second using GPU-based password cracking tools[1][6][7] (see John the Ripper benchmarks).[8] The rate of password guessing depends heavily on the cryptographic function used by the system to generate password hashes. A suitable password hashing function, such as bcrypt, is many orders of magnitude better than a naive function like simple MD5 or SHA. A user-selected eight-character password with numbers, mixed case, and symbols, with commonly selected passwords and other dictionary matches filtered out, reaches an estimated 30-bit strength, according to NIST. 230 is only one billion permutations[9] and would be cracked in seconds if the hashing function were naive. When ordinary desktop computers are combined in a cracking effort, as can be done with botnets, the capabilities of password cracking are considerably extended. In 2002, distributed.net successfully found a 64-bit RC5 key in four years, in an effort which included over 300,000 different computers at various times, and which generated an average of over 12 billion keys per second.[10]

Graphics processing units can speed up password cracking by a factor of 50 to 100 over general purpose computers for specific hashing algorithms. As an example, in 2011, available commercial products claimed the ability to test up to 2,800,000,000 NTLM passwords a second on a standard desktop computer using a high-end graphics processor.[11] Such a device can crack a 10-letter single-case password in one day. The work can be distributed over many computers for an additional speedup proportional to the number of available computers with comparable GPUs. However some algorithms run slowly, or even are specifically designed to run slowly, on GPUs. Examples are DES, Triple DES, bcrypt, scrypt, and Argon2.

The emergence over the past decade[when?] of hardware acceleration in a GPU has enabled resources to be used to increase the efficiency and speed of a brute force attack for most hashing algorithms. In 2012, Stricture Consulting Group unveiled a 25-GPU cluster that achieved a brute force attack speed of 350 billion guesses per second, allowing them to check 95 8 {\textstyle 95^{8}} password combinations in 5.5 hours. Using ocl-Hashcat Plus on a Virtual OpenCL cluster platform,[12] the Linux-based GPU cluster was used to "crack 90 percent of the 6.5 million password hashes belonging to users of LinkedIn".[13]

For some specific hashing algorithms, CPUs and GPUs are not a good match. Purpose-made hardware is required to run at high speeds. Custom hardware can be made using FPGA or ASIC technology. Development for both technologies is complex and (very) expensive. In general, FPGAs are favorable in small quantities, ASICs are favorable in (very) large quantities, more energy efficient, and faster. In 1998, the Electronic Frontier Foundation (EFF) built a dedicated password cracker using ASICs. Their machine, Deep Crack, broke a DES 56-bit key in 56 hours, testing over 90 billion keys per second.[14] In 2017, leaked documents showed that ASICs were used for a military project that had a potential to code-break many parts of the Internet communications with weaker encryption.[15] Designing and building ASIC-based password crackers is assumed[by whom?] to be out of reach for non-governments.[citation needed] Since 2019, John the Ripper supports password cracking for a limited number of hashing algorithms using FPGAs.[16] Commercial companies are now using FPGA-based setups for password cracking.[17]

Similarly, the more stringent the requirements for password strength, e.g. "have a mix of uppercase and lowercase letters and digits" or "change it monthly", the greater the degree to which users will subvert the system.[18]

In "The Memorability and Security of Passwords",[19] Jeff Yan et al. examine the effect of advice given to users about a good choice of password. They found that passwords based on thinking of a phrase and taking the first letter of each word are just as memorable as naively selected passwords, and just as hard to crack as randomly generated passwords. Combining two unrelated words is another good method. Having a personally designed "algorithm" for generating obscure passwords is another good method.

Research detailed in an April 2015 paper by several professors at Carnegie Mellon University shows that people's choices of password structure often follow several known patterns. For example, when password requirements require a long minimum length such as 16 characters, people tend to repeat characters or even entire words within their passwords.[20] As a result, passwords may be much more easily cracked than their mathematical probabilities would otherwise indicate. Passwords containing one digit, for example, disproportionately include it at the end of the password.[20] 17dc91bb1f
