The process ID is not static because this can't be used to identity, therefore, it includes excellent service providers like HTTP since it is allocated dynamically only to process whenever a process is initiated.
Sometimes its instance connectors are managed on numerous TSAPs. This can be implemented unless the process ID is being used as each procedure could have an identity.
If the password is longer, it requires more incorrect attempts to find it, so the system could identify a potential hacker attempt. Smaller but more complex passwords could be identified by mistype or forgotten passwords.
