Password Authentication Protocol (PAP)
This is the process of authenticating your account with a virtual network or website using a password for proving you are who you say you are.
Your user name and password are case sensitive. What this means is that only you will be able to have that user name and that password in that combination. This ensures that you are the correct person and that you do in fact have the authority to access the account that you were trying to log into.
In some cases the password must be stronger than others. For example if you are the administrator to a website it is typically required that your password be the highest strength possible in order to ensure the security of the website and the personal information of the members of the website.
There are typically 4 to 5 levels of security authentications. They are typically poor, fair, good, medium, and high. Most websites won’t let you complete your registration with less than a good rated password. The reason for this is because there are ways that someone can use password solving software to hack your account and access your personal information.
Most websites strive to bring their users the best possible security. I typically use a high security password for all of my membership or log in details. A strong password would consist of at least 8 characters with two capital letters two lowercase letters, two numbers and two different special characters such as *&.
