It must contain at least eight (8) characters {The current FBI standard is now at least ten (10) characters} , including at least one upper case letter, at least one lower case letter, at least one symbol, and at least one number. It may not contain words in the dictionary or proper names.
It should not be found in a dictionary. It should contain special characters and numbers. It should contain a mix of upper and lower case letters. There should be at least 8 characters. It should not be able to be guessed based on user information. It should not be shared with anyone. It should not be written down anywhere. Same password or similar passwords should not be used in other applications.

To find the total number of seven-digit numbers that contain the number seven at least once, we can use the principle of complementary counting. There are a total of 9,999,999 seven-digit numbers in total. To find the number of seven-digit numbers that do not contain the number seven, we can count the number of choices for each digit (excluding seven), which is 9 choices for each digit. Therefore, there are 9^7 seven-digit numbers that do not contain the number seven. Subtracting this from the total number of seven-digit numbers gives us the number of seven-digit numbers that contain the number seven at least once.
