Password strength is specified by the amount of information entropy, which is measured in shannon (Sh) and is a concept from information theory. It can be regarded as the minimum number of bits necessary to hold the information in a password of a given type.
HMAC-based one-time password ( HOTP) is a one-time password (OTP) algorithm based on HMAC. It is a cornerstone of the Initiative for Open Authentication (OATH). HOTP was published as an informational IETF RFC 4226 in December 2005, documenting the algorithm along with a Java implementation. Since then, the algorithm has been adopted by many ...
When fact and opinion-based questions are compared, the fact-based questions are more likely to be correctly remembered than opinion-based questions, but still far more likely than traditional passwords. Cognitive questions, with a group averaged as a whole, show relatively high guessability, much higher than traditional passwords but when ...
Password cracking. In cryptanalysis and computer security, password cracking is the process of recovering passwords [1] from data that has been stored in or transmitted by a computer system in scrambled form. A common approach ( brute-force attack) is to repeatedly try guesses for the password and to check them against an available ...
The Java Cryptography Extension ( JCE) is an officially released Standard Extension to the Java Platform and part of Java Cryptography Architecture (JCA). JCE provides a framework and implementation for encryption, key generation and key agreement, and Message Authentication Code (MAC) algorithms. JCE supplements the Java platform, which ...
Multi-factor authentication ( MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism. MFA protects personal data —which ...
Cognitive passwords use question and answer cue/response pairs to verify identity. "The password is dead" "The password is dead" is a recurring idea in computer security. The reasons given often include reference to the usability as well as security problems of passwords. It often accompanies arguments that the replacement of passwords by a ...
A strong password and password security are just one part of securing your account. Users with advanced permissions, and indeed all users, should be taking steps above and beyond these requirements to ensure the security of their accounts. Two-factor authentication is now available to all administrators, template editors and edit filter ...
