Passwords:TheFirst,Oldest,andRiskiestLineofDefense

Theconceptofpasswordsdatestoancienttimeswhentheywereusedasverbalcodestoguardsecretsor

Initially,passwordsweresimple,oftencomprisedof

commonwordsorshortnumericcombinations.However,ascomputingpowerincreased,thevulnerabilityofsimplepasswordsbecameapparent,leadingtothedevelopmentofmoresophisticatedpasswordpoliciesthatrequiredamixofcharacters,numbers,andsymbols.

PINs:SimplifyingSecure

wereusedprimarilyinbankingandpersonaldevices.

Theconceptwaspopularizedwiththeintroductionoftheautomatedtellermachine(ATM)inthe1960s,providingasecureandconvenientwayforuserstoaccesstheirbankaccountsusingacardandnumericcodeorPIN.PINs

offeredabalancebetweensecurityandsimplicity,making

themsuitableforeverydaytransactions.However,the

relianceonatypicallyfour-digitcodealsoraisedsecurityconcerns,leadingtotheadoptionofadditionalmeasures,suchaslockoutsaftermultipleincorrectattempts.

Incontrast,physicaltokensarepossession-based

EvolutionandChallenges

Whilepasswords,PINs,andphysicaltokenslaidthe
