2FA
  • kahe sõltumatu identsustõendiga autentimine - multiautentimise lihtsaim vorm

Good to know

Usage examples
  • Mistõttu, kui on vaja saavutada keskmisest kõrgemat turvalisust, nõutakse kaht identsustõendit korraga, eelistatult eri liikidest. Kui inimeselt tahetakse saada kaht identsustõendit korraga, siis öeldakse, et tegu on kaksikautentimisega ehk kahefaktorilise autentimisega (lühendist 2FA – two factor authentication).

two-factor authentication
Usage examples
  • Two-factor authentication provides a higher level of security than authentication methods that depend on single-factor authentication (SFA), in which the user provides only one factor -- typically, a password or passcode. Two-factor authentication methods rely on a user providing a password, as well as a second factor, usually either a security token or a biometric factor, such as a fingerprint or facial scan.
  • Two-factor authentication is a form of MFA. Technically, it is in use any time two authentication factors are required to gain access to a system or service. However, using two factors from the same category doesn't constitute 2FA; for example, requiring a password and a shared secret is still considered SFA as they both belong to the same authentication factor type: knowledge.
