To protect yourself from identity theft
With teleworking, multi-factor authentication has become a real necessity, whether remote connections go through terminal-server (TS), virtual private network (VPN) or even through an application hosted in the cloud.
Outsmart the clever foxes who would be tempted to pretend to be an employee: multi-factor authentication is the solution against identity theft by usernames and passwords.
What is Multi-Factor Authentication (MFA) and Two-Factor Authentication?
Multifactor authentication: A process for verifying identity that uses at least two different authentication factors.
Two-factor authentication: A method of verifying identity that uses precisely two different authentication factors.
The different authentication factors
In order to secure any connection or transaction of a user, the system will attempt to confirm their identity using various authentication factors.
The password is information that the user must know .
The token (or identification token - security token)
The token can either be a real token that the user must have when logging in or his smartphone.
