When it comes to authentication methods, there are quite a few different options worth checking out. Most people are well aware of some basic methods like passwords and two-factor authentication. However, there are alternative approaches well worth considering for those who desire additional security. All of the methods listed below are strong authentication methods, which also means they may be less convenient than some people would like.
4. Out-of-Band Phone Verification
While relying on any form of two-factor authentication is always a bit of a risk, out-of-band phone verification seems to check a lot of the right boxes. This method relies on calling a registered phone number for authentication purposes. Certain banks around the world implemented this method some time ago. The bank calls a registered number and asks users to enter their password over the phone. This method works well, assuming no one changes his or her registered phone number.
3. Peripheral Device Authentication
One of the newer types of authentication that is worth considering is called peripheral device recognition. The concept is self-explanatory, as peripheral devices are used as a second authentication factor. In most cases, this requires users to place a cryptographic marker on their existing devices, which could be virtually anything. For instance, one could utilize a USB drive or an external Blu-ray player. The only requirement is that it must be connected to one’s computer and recognized as a connected device.
Once the device is connected to the computer, the user can then log onto the platform supporting peripheral device recognition as an authentication method. This is a more than viable alternative to traditional two-factor authentication used by many platforms today. It is not the most convenient solution, although most people have at least one device on them at all times to use in this way.
2. Three-factor Authentication
