Now app developers can authenticate users via SIM cards using a new API for SIM-based verification. It has always been challenging for app developers when it comes to creating online accounts, as making the process too easy would invite trouble, and making it complex will turn genuine users away.
Traditionally we have been using usernames, emails, and passwords, now we are also using Multifactor or Two-factor authentication to overcome vulnerabilities by sending SMS code to authenticate the person possessing the mobile phone number.
The two-factor process is simple and widely used by many app developers across the world. Though hackers have now come up with exploits that enable them to crack this verification method. SIM swap frauds are turning out to be an easy option for them which reflects in the rapidly rising number of such incidents.
Other measures such as biometrics are secure though not every user has a smartphone that can scan a fingerprint or faceID. The other option is Authenticator apps, they are complex to use for normal users. Likewise, hardware tokens are secure too but suitable for tech-savvy users and not for an average joe.
SMS verification is not foolproof but when mobile numbers are bound with a SIM card it makes it difficult to tamper or copy as they are uniquely paired.
The SIM-based Authentication method prevents fraud and fake accounts as it uses the most cryptographically secure identifier in the form of the SIM card embedded in their mobile devices.
How SIM-based Authentication prevents SIM Swap Frauds and Account Takeover?
The growing number of SIM swap cases in recent times have led to FinTechs and cryptocurrency wallets being targeted. Though everyone using SMS verification is at risk leading to huge losses and a dent in the brand’s image.
Since the SIM-based authentication provides a simple fix, with an immediate and actionable response. With SubscriberCheck by tru.ID can keep fraudsters at bay as they tend to try and access the victim’s accounts usually within 24 hours.
If they attempt to change the SIM card a flag is raised and steps to tighten the security can be taken or completely block access to that number.
How the SIM-Authentication API Works?
Since the SIM card is already authenticated with the Mobile Network Operator (MNO), mobile users are able to make and receive phone calls and connect to the Internet.
SubscriberCheck from tru.ID uses authentication similar to the MNOs authentication mechanism. Resulting in the tru.ID API to first verify if the mobile number is active and paired with the SIM card on the mobile phone. The API also retrieves information if the SIM card is associated with the phone number is recently changed. These checks can be integrated easily with APIs and SDKs.
