Why Need to Change Password Frequently
In an era of high crime rate, people are used to password protect their important and private information such as an important word file, their personal computer, credit card, email, mobile phone etc. But just password protecting it is enough? How often should you change your password?
Frequent changing your password is a good practice to ensure your security. Password and any other authentication credential have an expiration data to limit the amount of time a lost, stolen, or forged credential can be used by someone else. Simple passwords used for long periods of time put Davenport University at risk. There are a large number of ways that a password can be compromised: someone watching as a password is entered (a.k.a. “shoulder surfing”), listening to network traffic as a password as transmitted (a.k.a. “sniffing”), or attacking the password directly by attempting to guess it (a.k.a. “brute-force cracking”). By requiring that password be changed periodically, it limits Davenport’s risk from compromised credentials.
Then the question is how long should we change our password? It is highly recommended to change password every few month. A hacker need to spend time to guarantee success the attackers attempt to try every possible combination of letters, numbers, and symbols. Even with fast modern computers this still takes a significant amount of time to compute all the different possibilities and test them. The process can take weeks, months, or years, depending on several factors that we will cover later. Periodically change your password make it more difficult for attackers to compromise.

Most people only use lower case letters when create a password, but an eight character password consisting of only lower-case letters has approximately 209 billion (26^8 or 209E+9) possible password combinations. If you use upper and lower case letters plus numbers, there are 218 trillion (62^8 or 218E+12) possible passwords. Include symbols in that and the list of possible passwords increases to 6 quadrillion (94^8 or 6E+15). So using numbers or special characters in a password is highly recommended.
