PPemail strongly recommends clients use the highest level of security for all PPemail passcodes (a more descript term than ‘password’). Strong passcodes are now basic for all online activity and essential for privacy.
Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks. In its usual form, it estimates how many trials an attacker who does not have direct access to the password would need, on average, to guess it correctly. The strength of a password is a function of length, complexity, and unpredictability.
The suggestions for passcodes continue to evolve. Earlier rules included such recommendations as:
But requiring such features actually decreases security because any constraint increases predictability. Security experts, therefore, no longer support requiring specific passcode features.
Strong passcodes are measured using a version of “information entropy,” a concept that in passcode parlance means uncertain, random, and unpredictable (select the image for details). A contemporary heuristic for passcodes is: use random sequences in long strings. The challenge, of course, is that random sequences not only prevent nefarious access, they also limit legitimate access because random sequences challenge human recall. Such human limits belie another rule, “Never write down your password, anywhere.”
Your professional passcodes should be strong. PPemail suggests your passcodes
In sum, the strongest passcodes need not be overly complicated but should include at least a ten-character string of letters, numbers, and/or symbols. The more uncertain the characters the better.
We created PPemail for professionals who need portable yet secure email, file storage, and internet services. Because clients pay for our services, by contract, we do not and will not commodify their activity. (MORE)
