Co je dvoufaktorov\u00e1 autentizace?<\/strong><\/h2>\n\n\n\n

2-Factor Authentication, tak\u00e9 zn\u00e1m\u00fd jako 2FA, je metoda zabezpe\u010den\u00ed, kter\u00e1 pro p\u0159\u00edstup k online \u00fa\u010dtu vy\u017eaduje dv\u011b r\u016fzn\u00e9 formy dokladu toto\u017enosti. Obvykle se tyto faktory d\u011bl\u00ed do t\u0159\u00ed kategori\u00ed: n\u011bco, co zn\u00e1te (heslo), n\u011bco, co m\u00e1te (telefon, fyzick\u00fd token) a n\u011bco, \u010d\u00edm jste (biometrie).

1. Vy\u0161\u0161\u00ed bezpe\u010dnost a ochrana<\/h3>\n\n\n\n

2Factor Authentication poskytuje v\u00fdznamn\u00e9 dodate\u010dn\u00e9 zabezpe\u010den\u00ed pro va\u0161e online \u00fa\u010dty.

5. Rostouc\u00ed p\u0159ijet\u00ed v pr\u016fmyslu<\/h3>\n\n\n\n

2Factor Authentication se st\u00e1v\u00e1 b\u011b\u017enou prax\u00ed v mnoha online slu\u017eb\u00e1ch.
