Two-step authentication involving mobile phones and smartphones provides an alternative to dedicated physical devices.

Variations include both longer ones formed from multiple words a passphrase and the shorter, purely numeric, personal identification number PIN commonly used for ATM access.
Traditionally, passwords are expected to be memorized. Many secret questions such as "Where were you born? Possession factors "something only the user has" have been used for authentication for centuries, in the form of a key to a lock.
The basic principle is that the key embodies a secret which is shared between the lock and the key, and the same principle underlies possession factor authentication in computer systems.
A security token is an example of a possession factor. Disconnected tokens have no connections to the client computer.
They typically use a built-in screen to display the generated authentication data, which is manually typed in by the user.
This type of token mostly use a "one-time password" that can only be used for that specific session. Connected tokens are devices that are physically connected to the computer to be used.
Those devices transmit data automatically. A software token a. Software tokens are stored on a general-purpose electronic device such as a desktop computer , laptop , PDA , or mobile phone and can be duplicated.
Contrast hardware tokens , where the credentials are stored on a dedicated hardware device and therefore cannot be duplicated, absent physical invasion of the device.
A soft token may not be a device the user interacts with. Typically an X. These are factors associated with the user, and are usually biometric methods, including fingerprint , face , voice , or iris recognition.
Behavioral biometrics such as keystroke dynamics can also be used. Increasingly, a fourth factor is coming into play involving the physical location of the user.
While hard wired to the corporate network, a user could be allowed to login using only a pin code while off the network entering a code from a soft token as well could be required.
This could be seen as an acceptable standard where access into the office is controlled. Systems for network admission control work in similar ways where your level of network access can be contingent on the specific network your device is connected to, such as wifi vs wired connectivity.
This also allows a user to move between offices and dynamically receive the same level of network access in each. Many multi-factor authentication vendors offer mobile phone-based authentication.
Some methods include push-based authentication, QR code based authentication, one-time password authentication event-based and time-based , and SMS-based verification.
SMS-based verification suffers from some security concerns. Phones can be cloned, apps can run on several phones and cell-phone maintenance personnel can read SMS texts.
Not least, cell phones can be compromised in general, meaning the phone is no longer something only the user has. The major drawback of authentication including something the user possesses is that the user must carry around the physical token the USB stick, the bank card, the key or similar , practically at all times.
Loss and theft are risks. Many organizations forbid carrying USB and electronic devices in or out of premises owing to malware and data theft-risks, and most important machines do not have USB ports for the same reason.
Physical tokens usually do not scale, typically requiring a new token for each new account and system. Procuring and subsequently replacing tokens of this kind involves costs.
In addition, there are inherent conflicts and unavoidable trade-offs between usability and security.
Two-step authentication involving mobile phones and smartphones provides an alternative to dedicated physical devices.
To authenticate, people can use their personal access codes to the device i. The passcode can be sent to their mobile device  by SMS or can be generated by a one-time passcode-generator app.
In both cases, the advantage of using a mobile phone is that there is no need for an additional dedicated token, as users tend to carry their mobile devices around at all times.
As of [update] , SMS is the most broadly-adopted multi-factor authentication method for consumer-facing accounts. In and respectively, both Google and Apple started offering user two-step authentication with push notification [ clarification needed ] as an alternative method.
Security of mobile-delivered security tokens fully depends on the mobile operator's operational security and can be easily breached by wiretapping or SIM cloning by national security agencies.
Advances in research of two-factor authentication for mobile devices consider different methods in which a second factor can be implemented while not posing a hindrance to the user.
For example, by recording the ambient noise of the user's location from a mobile device and comparing it with the recording of the ambient noise from the computer in the same room in which the user is trying to authenticate, one is able to have an effective second factor of authentication.
The second Payment Services Directive requires " strong customer authentication " on most electronic payments in the European Economic Area since September 14, In India, the Reserve Bank of India mandated two-factor authentication for all online transactions made using a debit or credit card using either a password or a one-time password sent over SMS.
Vendors such as Uber have been pulled up by the central bank for allowing transactions to take place without two-factor authentication.
Existing authentication methodologies involve the explained three types of basic "factors". Authentication methods that depend on more than one factor are more difficult to compromise than single-factor methods.
IT regulatory standards for access to Federal Government systems require the use of multi-factor authentication to access sensitive IT resources, for example when logging on to network devices to perform administrative tasks  and when accessing any computer using a privileged login.
NIST Special Publication discusses various forms of two-factor authentication and provides guidance on using them in business processes requiring different levels of assurance.
In , the United States ' Federal Financial Institutions Examination Council issued guidance for financial institutions recommending financial institutions conduct risk-based assessments, evaluate customer awareness programs, and develop security measures to reliably authenticate customers remotely accessing online financial services , officially recommending the use of authentication methods that depend on more than one factor specifically, what a user knows, has, and is to determine the user's identity.
Due to the resulting confusion and widespread adoption of such methods, on August 15, , the FFIEC published supplemental guidelines—which states that by definition, a "true" multi-factor authentication system must use distinct instances of the three factors of authentication it had defined, and not just use multiple instances of a single factor.
According to proponents, multi-factor authentication could drastically reduce the incidence of online identity theft and other online fraud , because the victim's password would no longer be enough to give a thief permanent access to their information.
However, many multi-factor authentication approaches remain vulnerable to phishing ,  man-in-the-browser , and man-in-the-middle attacks.
Multi-factor authentication may be ineffective  against modern threats, like ATM skimming, phishing, and malware.
