Master Password Master Password Master Password is an algorithm designed by Maarten Billemont for creating unique passwords in a reproducible manner. It differs from traditional password managers in that the passwords are not stored on disk or in the cloud, but are recreated every time by using information entered by the user; most importantly, their full name, a master password, and a unique name for the service the password is intended for. By not storing the passwords anywhere, this approach tries to make it harder for attackers to steal or intercept them. It also removes the need for synchronization between devices, and
Most recent common ancestor all of the modern population. Due to pedigree collapse, modern individuals may still exhibit clustering, due to vastly different contributions from each of ancestral population . Most recent common ancestor In biology and genealogy, the most recent common ancestor (MRCA, also last common ancestor (LCA), or concestor) of any set of organisms is the most recent individual from which all the organisms are directly descended. The term is also used in reference to the ancestry of groups of genes (haplotypes) rather than organisms. The MRCA of a set of individuals can sometimes be determined by referring to an established pedigree.
