What is a strong 4 digit password?
Every four-digit combination that starts with 19 ranks above the 80th percentile in popularity. Month/day combinations—those in which the first two digits are between 01 and 12 and the last two are between 01 and 31—are also popular.
The greatest four-digit number, using only one digit is 9,999 (9,999 is the greatest four-digit number too). The greatest four-digit number, using two different digits is 9,998. The greatest four-digit number, using all different digits is 9,876.
The safest 4-digit PIN is '8068' — or at least it was, until researchers at Data Genetics told everyone this week. The researchers there went through a set of 3.4 million four-digit personal identification numbers and found "8068" came up only 25 times.
So 9 * 10**6, or 9000000. If it can start with zero but no numbers can repeat than each digit has one less options than the one before it because one number has been used. so 10 * 9 * 8 * 7 * 6 * 5 * 4, or 604800.

There are 10,000 possible combinations that the digits 0-9 can be arranged into to form a four-digit code.
An 8- or 12-digit PIN is more secure than a traditional 4-digit number, but it's also harder to remember, unless it is already in your memory.

PIN is backed by hardware
Windows doesn't link local passwords to TPM, therefore PINs are considered more secure than local passwords.
So, smallest four digit number is 1000. Q. What is the ratio of the smallest two digit number to the smallest four digit number? Q.
If a password is only four or five characters (whether they are just numbers or a combination of numbers, letters and symbols), there's a very high chance that it will be hacked instantly. However, if a password is only numbers and up to 18 characters, it could take a hacker up to nine months to crack the code.
So, the greatest 4 digit number will be 9,999. Q.
Look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number.
countable noun. A password is a secret word or phrase that you must know in order to be allowed to enter a place such as a military base, or to be allowed to use a computer system.
Make sure you use at least three of the following; an upper case letter, a lower case letter, a number, and a special character. The combination of various character types make a password harder to crack. Password cracking tools work on common combinations of characters using a password cracking dictionary.
Perhaps part of the answer lies in a seminal paper published in 1956 by the psychologist George A Miller called “The Magical Number Seven, Plus or Minus Two”. Miller claims that it is more than just coincidence that the number 7 seems to be all around us.
11: Lucky 12
Just as 13 is considered one of the unluckiest of all numbers, 12 is considered the rare lucky number that happens to also be even. The origins of this superstition are sketchy, but some sources suggest that 12 gained its lucky rep simply because it's so nicely divisible.
What is the luckiest number in America?
Luckiest Numbers
In the US, as well as in many Western cultures, the numbers 3, 7 and 12 are considered lucky.
A 4-digit number is in the thousands. For example, 7839, 2039, 5748 and 4780 are all 4-digit numbers, because they're written with four digits or numerals. Each of these numerals has a different place value. From left to right they are: thousands, hundreds, tens and ones.
We see that our formula gives that there are 5,040 possible 4-digit lock combinations.
A number N is said to be a mystery number if the number can be expressed by the sum of two numbers. Note that these two numbers must be reverse of each other. It lies between 22 to 198, i.e. 22<=N<=198.

It's very simple. In 4 decimal digits there are 10,000 (0000 to 9999) possible values. The odds of any one of them coming up randomly is one in 10,000. Save this answer.
According to the study, these are the most frequently used PINs: Four-digit PINs of the following kinds: 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212.
A strong 6-Digit PIN should not be predictable and cannot be easily guessed. We highly recommend that users choose a 6-Digit PIN that avoids these common pitfalls, as outlined below: No DOB (forward or backward) e.g. DDMMYY, YYMMDD, MMDDYY.
A personal identification number (PIN), or sometimes redundantly a PIN number or PIN code, is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system.
A prudently chosen four-digit PIN is secure enough, mainly because manufacturers limit the number of attempts to enter a PIN.
Can a bank tell you your PIN?
If you've forgotten your debit card PIN, some banks may offer a way to retrieve it through their website or app. You can also call a customer care representative, or find a local branch for help. You'll probably still need to verify your account ownership and may be directed to reset the PIN for security reasons.
Thus, smallest 4 digit number is 1000.
the greatest four-digit number is 9999.
We know that 4- digit number is said to be an odd number, if unit place digit is an odd number (i.e. 1 or 5 ) Given digits are 1,2,4 and 5. Total such odd numbers are 4125 ,4215 ,1245 ,1425, 2145, 4251, 4521, 5241, 5421, 2451 and 2541.
Research suggests thieves can guess one in five PINs by trying just three combinations. How easy would it be for a thief to guess your four-digit PIN?
A 4 digit PIN number is selected. What is the probability that there are no repeated digits? There are 10 possible values for each digit of the PIN (namely: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9), so there are 10 · 10 · 10 · 10 = 104 = 10000 total possible PIN numbers.
A "googol" is the number 1 followed by 100 zeroes. The biggest number with a name is a "googolplex," which is the number 1 followed by a googol zeroes.
The greatest 4-digit number is 9999. 9999 = 3 × 3 × 11 × 101 [Prime factors are the factors of the given number which are prime.] Thus, the prime factors of the greatest 4-digit number 9999 are 3, 3, 11, 101.
Password: m#P52s@ap$V
This is a great example of a strong password. It's strong, long, and difficult for someone else to guess. It uses more than 10 characters with letters (both uppercase and lowercase), numbers, and symbols, and includes no obvious personal information or common words.

How do you make a good 4 digit PIN?
Use a meaningful address
Your best bet: use the four-digit street address of a childhood friend, a former workplace or another significant place. Numbers with personal significance are easy to remember and hard to guess. Note: Avoid using your own address since thieves could access this information.
- At least 12 characters long (the longer, the better).
- Has a combination of upper and lowercase letters, numbers, punctuation, and special symbols.
- Random and unique.

Your security PIN is similar to the PIN on your ATM/debit card. Anyone who knows your PIN has access to your account. For that reason, you should protect your PIN and avoid disclosing it to anyone you do not wish to provide access to your account.
If a password is only four or five characters (whether they are just numbers or a combination of numbers, letters and symbols), there's a very high chance that it will be hacked instantly. However, if a password is only numbers and up to 18 characters, it could take a hacker up to nine months to crack the code.
Shockingly, it appears that one in every 10 people uses the same pin – 1234. Theoretically, there are 10,000 possible four-digit combinations the numbers 0 to 9 can be arranged into, and if everyone selected a number entirely at random that would offer a reasonable level of protection.
So, smallest four digit number is 1000. Q. What is the ratio of the smallest two digit number to the smallest four digit number?
