Online privacy and security is the biggest threat to sustainable digital growth. Today, authenticating a user is a very tricky process given the risks posed by many authentication mechanisms to the service provider as well as to the user. Service providers with large user stores tend to move their security aspects into identity providers (IDPs) leaving the safety and convenience of the user stores and the authentication process in the hands of the IDP. WSO2 Identity Server is one of the leading identity providers available in the market that supports a massive number of protocols and authentication mechanisms proven to be useful and convenient. Apart from the traditional username and password authentication approach, multi-factor authentications with higher security features are also available in the WSO2 Identity Server.

What is Mobile Connect?

Mobile connect is a mobile operator facilitated authentication solution that provides simple, secure, and convenient access to online services. It’s the convenient alternative to passwords that protect customer privacy. This concept, introduced by the GSMA Association, provides a global and secure authentication platform by combining the user's unique mobile number and PIN to verify and authenticate the user, anywhere anytime. It allows swift logins without the need to type usernames or passwords.

Why Mobile Connect?

In a world driven by technology, the mobile device has connected with the most number of users around the globe, connecting people from rural areas to the greater metropolis of the world. Consumers around the world are increasingly using mobile devices to access a wide range of online services while banks, government organizations, hospitals and merchants are adopting a “Mobile First” approach to the design and delivery of services. Over time, consumers around the world expect the mobile device to play a vital role in their lives with many of their daily activities being performed by the mobile device itself.

The 21st century is a digital era with cyber attacks becoming extremely common and rampant; many organizations are still concerned on how secure their systems and products are. The levels of security needed for data and information provided today have made access to these resources unavailable without proper registration with the resource provider. Therefore, it becomes mandatory for users to ‘sign up’ with the system, which means users have to remember numerous usernames and passwords. What if we had a simple and secure mechanism to carry out the authentication process without much hassle, in just seconds? Why can't we take advantage of having a mobile device as a sensible and secure way of authentication?

Since many people are becoming more reliant on digital services, consumers are vary of maintaining multiple usernames and passwords and also the use of a variety of security tokens. The mechanism of access and concerns about privacy implications of sharing personal data online to mostly unknown parties is yet another frustration. Today, both consumers and service providers look for a better authentication and identification solution, and mobile connect can be described as a universal authentication solution.

For service providers

Service providers seek more convenient and faster solutions for authentication and identification as it plays a vital role in securing a strong customer base within the system. Failing to adhere to these usability aspects will prompt users to drop and seek alternatives that are more user friendly. Due to this competitive industry and technology driven world, the service providers seek the following three main aspects for their systems, which are also provided by GSMA Mobile Connect without any hassle. Service providers are interested in Mobile Connect’s Potential to

  • Accelerate and ease verification and authentication to make it easier to interact with consumers.
  • Reduce friction (e.g. dropped logins, abandoned shopping carts) to increase registration and engagement.
  • Enable access to operator’s subscriber attributes (regardless of their operator) to provide better and more secure services.

For consumers

Research shows that most consumers would likely adopt Mobile Connect as their primary mode of log-in for most online services, applications, and websites. According to research done by GSMA, almost 90% of 1,000 smartphone users around the world were attracted to Mobile Connect’s three main functionalities.

  • Universal log-in for multiple websites
  • Strong security
  • Control over personal data

Studies show that online services, websites, banks, and government agencies are eyeing widespread deployment of Mobile Connect to check attributes that can be indicators of fraud, such as individuals’ locations, while at the same time increasing end-user experience.

Consumer research statistics

By reducing the need for remembering the number of usernames and passwords, Mobile Connect eliminates the frustration of the end user, which drives more repeat businesses and ensures less abandoned transactions

Figure 1

The following statistics (as depicted in Figure 1) were obtained by "GSMA’s 2015 Consumer Research" which is related to use perspective on Cyber Security. From the overall number of users

  • 87% would prefer just one strong password to remember
  • 86% have left websites when asked to register or sign-up
  • 86% are concerned about security when online
  • 88% want reduced risk of identity theft and credit card fraud
  • 81% don't feel that they are getting much value from their personal data as third-parties do
  • 68% are more likely to return to a site that remembers them without a username or a password

This gives a much stronger argument as to why Mobile Connect will dominate the digital authentication industry in the near future.

How Mobile Connect works

Figure 2

The given sequence in Figure 2 depicts the mobile connect flow, from signup/login to the complete authentication in just 4 steps. The authentication process is carried out through your mobile device rather than your personal information.

  • Step 1: Click on the "Sign up" or "Log in" button
  • Step 2: Enter your mobile number (optional)
  • Step 3: Confirm your authentication via the mobile device (USSD, SMS, etc.)
  • Step 4: Login process is complete

Step 1

This is where the user will be selecting an authentication mechanism that will best suit the user’s authentication needs. Without loss of generality, assume that the user picks Mobile Connect to proceed with the authentication to the service. This will let the service provider know that the Mobile Connect authentication process has been initiated and the service provider will trigger the necessary APIs to carry out the required processes.

Step 2:

If the user is using a network connection that’s not based on a mobile network operator, such as GPRS, 3G or 4G, the user will be prompted to enter the mobile number in order to connect the authentication process with the user’s mobile device. If the user is using a mobile device with a network connection provided by a mobile network operator, Mobile Connect will automatically identify the user’s mobile number and will proceed with the authentication process.

Step 3:

The only mode of user interaction in the authentication process is where the user will have to accept the login request sent to the mobile device by Mobile Connect servers. If the user is using the mobile device for this purpose, the authentication will happen seamlessly without the user’s interaction, which makes the proc

ess much more convenient and user friendly.

Step 4:

Following completion of the above steps, the user will be successfully logged into the online service, where the user’s privacy and convenience is fully assured.

Concepts of Mobile Connect

Mobile Connect assures three main concepts to the users that are briefly explained below:


    Trusted operators will expose their APIs, supporting OpenID connect with the Mobile Connect Profile specified by the GSMA.


    This is a consistent log in experience to all providers across any device. It could be a mobile device, laptop, tab6let or even a TV.


    The GSMA has all license needs to comply with the privacy policies of each trusted operator. No personal data will be share

Social media vs. Mobile Connect authentication

After crunching all the numbers and information, you must be wondering, how is this different from social media federated authenticators. In most web services and service providers, "Log in with Social Media" plays a major role.

The collaboration and sharing made possible by Web 2.0 also come with a specific set of risks in terms of privacy. Social networking sites are user hubs, where it’s meant for collecting a set of users to one place. And this is like the jackpot for attackers where they can use the information to earn a lot of return on investment if they are going after the social media users.

Many social media users do not think of this concept where their privacy is being dragged to a money-making business by many applications and service providers. The reason for social media being a free service to users and the ability for other applications to connect to social media networks via user permission is to gain insights and knowledge of a user’s day to day activities to cater to different needs of the user. Scientists and philosophers still argue on this fact where even though it is a privacy implication for the user, the modern world is driven by the data and patterns of user activity throughout the world.

Mobile Connect is a powerful tool that can be used to move us all away from using social media as an easier way to log in, where social media authentication is tagged along with a lot of unnecessary risks. Even though social networks can eliminate the need for passwords, there is no assurance that this information is secure. But with Mobile Connect and its privacy policies, empowered by GSMA, no information is available to service providers without the user's consent, making logging in and signing up much safer and private.

How safe is Mobile Connect?

With the typical username and password schemes, or social media authentication schemes, there is a high risk and danger of losing your privacy if an attacker can discover or guess the password of the user. There are many ways that the attackers might use to gain access to accounts. Brute force attacks, SQL injection, session hijacking, browser cookies, are some examples among others. In the case of social media, access to one social media account may expose all other accounts via social media login.

However, with Mobile Connect, users use their unique mobile number (MSISDN) and mobile device to prove their identity. Since a mobile device is considered to be a single-user device, the user who’s in possession of the device is the only person who can log in to the service through Mobile Connect.

What happens if the mobile device is stolen?

In this scenario, the user always has the option of calling the respective mobile network operator and reporting that the mobile device is lost or stolen. To avoid unnecessary parties from accessing your private accounts via the stolen device, we can either cancel the sim card or the mobile connect facility of the mobile number.

Can the security level be increased in Mobile Connect?

The levels of security in each application is different from its environment and the purpose of use. For example, a bank or an e-payment site would need a higher level of security than an ordinary information system. Considering these possibilities, Mobile Connect provides the developer with options of selecting a level of Security, which is also known as the Level of Assurance (LoA).

LoA describes the degree of confidence in various security processes including authentication (according to the ISO/IEC 29115 Standard). It provides assurance that the entity claiming a particular identity is the entity to which that identity was assigned.

During the Mobile Connect Authorization process, the application declares the degree of confidence required in the returned identity (for more read Mobile Connect for Developers). The greater the risk associated with an erroneous authentication, the higher the LoA recommended.

There are four LoAs

  1. Level of Assurance 1 (not supported by Mobile Connect)
  2. Level of Assurance 2 (Requires a simple key press)
  3. Level of Assurance 3 (Requires a simple key press + pin)
  4. Level of Assurance 4 (not supported by Mobile Connect)

For more details view Level of Assurance (LoA)
