From two-factor authentication to multi-factor authentication

Modern authentication methods for more security

What is multi-factor authentication and why
is cidaas the ideal solution?

Multi-factor authentication (MFA), also known as two-factor authentication (2FA), has become one of the most important tools for protecting data. Last but not least, media attention has ensured that multi-factor authentication has almost become the standard for companies. Multi-factor authentication uses at least two different factors from the categories knowledge, possession and inherence to provide strong authentication. Decisive for successful multi-factor authentication are the authentication methods offered and when it makes sense to use event-based multi-factor authentication. Otherwise, it can quickly be perceived as annoying and uncomfortable.

What is the difference between multi-factor authentication and two-factor authentication? 

Two-factor authentication consists of two different factors. A factor is a component of authentication in each case. It can be classified into one of the following categories Knowledge, Possession, and Inherence (Biometrics). Two-factor authentication is a special case of multi-factor authentication (MFA). MFA requires at least two factors to verify identification.

What are the advantages of multi-factor authentication over two-factor authentication? 

In many cases, multi-factor authentication and two-factor authentication are used interchangeably. Nevertheless, there are some use cases in which multi-factor authentication is used and also makes sense. If you consider a website login with username and password, as well as an additional code via e-mail as OTP, this is a classic two-factor authentication. However, if you use a different method instead of an e-mail OTP, e.g., a push OTP in an app on the smartphone, and additionally protect this app with device biometrics, for example, you create a higher level of security; firstly, username and password (knowledge), then the push OTP to the smartphone (ownership) and further the device biometrics (inherence). In this case, 3 factors are combined. 

Such a concatenation of different authentication methods into a multi-factor authentication is often seen in banking apps. However, due to increasing digitization, all sensitive data, e.g., health data, require a very high level of protection. The concatenation described above impressively shows that not only does security increase, but in particular that the customer experience does not suffer. The device biometrics, e.g., FaceID on the iPhone, are simple, fast, and established.

Protection against identity theft

Identity theft is a continuous danger for users. Criminals manipulate users brazenly to access and abuse their data. Every company is thus a direct target of cybercrime. Hacked accounts cause financial damage and, above all, damage to the company’s reputation. With multi-factor authentication and fraud and botnet detection integrated in cidaas, you can protect your customers and offer an additional option for verifying user identity. With multi-factor authentication and many other features such as API-Security and fraud detection you can increase security.


Security and flexibility

A second factor ensures more security. Now it generally entails additional work, because in case of any doubt a new authentication must be carried out or a separate device must be available. With cidaas, you have the choice of how the authentication should look like – individually, according to your needs.

Strong authentication is not necessary for every access. Instead, you first specify which authentication methods you want to authorize on each application. In this way, you have already achieved the first level of security. If additional authentication is required for certain activities, set up an event-related multi-factor authentication. In addition, cidaas recognize suspicious behaviour, so that only in suspicious cases does the user have to verify his identity via an additional factor.

Every industry has capital in the form of knowledge, buildings and employee, partner or customer data. With cidaas you can quickly and easily introduce strong security mechanisms such as multi-factor authentication.

Multi-factor authentication in various business sectors

multi-factor authentication


Employees often have access to internal, confidential and security-sensitive data and applications. An essential protection is that applications are protected by secure authentication. A “strong” password is no longer enough. The enticement is too great to reuse one or change the old one only slightly. Passwords can also be passed on. Provide modern authentication methods with cidaas, detect suspicious behaviour and demand a second factor if necessary.

Business to Consumer/ Customer

Customers, their data and their trust are essential for the success of a company. This demands protection of this data and yet comfort must not be put on the back burner. The customer is the focus of attention. Give them the opportunity to choose their own authentication methods. Realize a smart 2FA that only requests further authentication when it is needed. Thereby you achieve security and comfort at the same time.

Business to Employee

Digital collaboration with partners and customers and the use of shared applications is now standard practice in every company. With cidaas you provide modern authentication methods. You recognize suspicious behavior and request a second factor if necessary. Determine individually which accesses require a second authentication. With cidaas’ MFA and other functionalities, such as group management, collaboration is successful.

Frequently Asked Questions

What is multi-factor authentication?

Multi-factor authentication (MFA) means a user identifies himself or herself through another factor. This enables him/her to verify his/her identity. A factor can come from one of three categories: knowledge, possession or biometrics. An example for the factor knowledge is the password. By itself it is only one factor and not enough for a multi-factor authentication. An example of an implicit multi-factor authentication is the TouchID. With TouchID, a device with a fingerprint scanner is required (possession) and a fingerprint (biometrics) to confirm the identity. With the right login procedures, e.g. passwordless, an MFA can be both convenient and secure.

What is smart multi-factor authentication?

Smart multi-factor authentication means that only one additional factor is required if it is necessary due to the situation or context. By means of intelligent fraud detection, for example, a second factor can be requested in case of suspicion.

What does strong customer authentication mean?

The term strong customer authentication is primarily a regulatory requirement and was coined by BaFin. It refers to an authentication process that consists of at least two elements from two different categories. The categories are knowledge, possession and biometrics. The EBA (European Banking Authority) has compiled a list of procedures that are classified as SCA (Strong Customer Authentication). It explicitly states, among other things, that the classification as an SCA depends on the implemented approach of the authentication procedure.

What is the difference between multi-factor authentication and two-factor authentication?

A two-factor authentication consists of two different factors. One factor is a component of the authentication. It can be classified into one of the following categories: knowledge, possession and biometrics. Two-factor authentication is a special case of multi-factor authentication (MFA). The MFA requires at least two factors to verify identification.
