The safest authentication method is authentication using a smart card.
Smart Card Authentication uses a physical card along with a smart card reader and software on the workstation to validate users into enterprise resources like workstations and applications. Although smart card authentication offers a terrible user experience and is expensive to deploy and maintain, it is very secure.
Because smart card authentication requires a physical credential, a hardware card reader, and software, it is expensive and difficult to administer. Smart cards are only used in the most secure workplaces, such as three-letter agencies of the federal government or privileged access at a financial institution, as these environments frequently forbid employees from carrying smartphones to and from work.
