TWO-FACTOR (TWO-STEP) AUTHENTICATION

wo-factor (or two-step) authentication appeared in 1984. Verification of the user's identity using this technology is performed on the basis of two types of identification data. This can be information known to the user (password, PIN code), a device available to the user ( smart card, token , one-time password generator) or biometric parameters of the user , which are his physical features (fingerprint, vein pattern on the palm, retina).

The use of two-factor authentication virtual phone number service allows for the effective resolution of problems arising in the case of password access and, as a result, ensures automatic implementation of access regulations to the company's information resources.

Two-factor authentication significantly increases the level of system security due to the fact that adding an additional authentication level makes it more difficult for an intruder to attempt to gain unauthorized access to data (UAD). Therefore, this technology is widely used in modern companies.




To organize two levels of authentication, various combinations of authentication factors (data) are used. One of the most common methods of two-factor authentication is authentication by card . In this case, at the first level, a key carrier (smart card or token) is used to verify the user's identity, and at the second level, a PIN code or biometric parameters of the owner of this key carrier. It is difficult for an intruder to steal both authentication factors at the same time, so with this approach, the likelihood of unauthorized access to data is significantly reduced.
