A Future That Preserves Privacy and Ensures eSafety

xString Tech Empowers End Users and Enables Confidential Client Systems

Offers an end-user application that allows users to take control of their own (email-less, biometric-less, name-less, DoB-less, address-less) digital credentials that can be used with a single strike for both sign-up and sign-in, while providing strong multi-factor authentication that confidential client systems can leverage — a secure and advanced Impersonation-Resistant Credential (iRC) authentication system powered by xString Tech.

Strengthens user privacy and data protection through data minimisation, allowing users to sign up or sign in without needing to provide personal phone numbers, email addresses, biometric data, personal device information, other personally identifiable information, or usage pattern data — a privacy-conscious and advanced authentication platform backed by xString Tech.

Provides a seamless proof-of-age verification solution using near zero-knowledge with Proof of Age Digital Certificates (PoADC), without compromising user privacy through legacy approaches such as biometric data analysis, non-consensual data collection by platforms to estimate user age, or uploading government-issued identity documents onto commercial digital platforms — instead, offering a minimum-age-assured, standards-compliant, and privacy-preserving advanced authentication solution driven by xString Tech.

Our goal is to empower end users and enable new and existing IT platforms, confidential client systems, and governments to better serve their citizens, communities, and system users in realistic and responsible ways.

xString Tech Addresses Significant Challenges in User Authentication

xString Tech has developed a leading technology solution based on deep insights into the common challenges faced by end users, service providers, platform providers, trusted credential providers, and professional accreditation bodies.

Issue Topic: Privacy and Consent

Problem Definition 1: Collecting Identity Attributes for Sign-up and Login

The traditional process requiring users to provide identity attributes such as email addresses, phone numbers, and biometrics during sign-up and login presents significant challenges for both users and service providers. For minors and people with disabilities, the need for guardian consent complicates the process and may exclude those unable to meet the requirements. For privacy-conscious adults, the lack of alternative login methods or non-invasive data collection options can lead to reluctance or refusal to engage with the platform. Service providers face the challenge of maintaining legal compliance, ensuring security, and building trust with users while balancing privacy concerns. To accommodate diverse users, more flexible, inclusive, and privacy-respecting authentication solutions are necessary.

Issue Topic: Privacy Intrusion and Security

Problem Definition 2: Username, Password and Biometric Authentication

The traditional username and password model creates friction for both users and service providers. For users, it creates burdens around memorisation, security risks, and usability challenges. For service providers, it presents technical, security, and legal challenges. As cyber threats grow in complexity, reliance on this model is becoming increasingly insufficient, leading many to explore alternatives such as intrusive biometric solutions, including invasive data collection involving physical location, phone ID, device ID, and OS type, in the name of enhancing security.

Issue Topic: Privacy Concerns and Interconnectivity

Problem Definition 3: Proof of Age and Credential Verification

The traditional process of proving a user’s age and verifying credentials presents numerous challenges for both users and service providers, further exacerbated by the lack of interconnectivity between service providers and accredited identity or credentialing bodies. From the user’s perspective, this leads to privacy concerns, trust issues, and a fragmented verification experience. Service providers, on the other hand, must navigate complex regulatory environments and manage operational inefficiencies, while maintaining trust and security. To address these issues, there is a critical need for more integrated, secure, and user-friendly solutions that streamline the verification process, reduce friction, and support minimum age assurance compliance without compromising user trust or data privacy.

Issue Topic: Complexity and Friction

Problem Definition 4: Sign-up and Sign-in with Multiple Steps and Devices

Traditional sign-up and sign-in processes involving multiple steps and MFA create friction for both users and service providers. From the user’s perspective, the complexity of managing multiple steps, devices, and passwords leads to frustration, barriers to access, and a less convenient experience. From the service provider’s perspective, the challenge lies in balancing security with user experience, managing higher operational costs, and reducing user abandonment caused by complicated authentication flows. To improve both security and usability, there is a growing need for innovative, frictionless authentication solutions that streamline sign-ups and sign-ins without compromising security.

In practice, these providers usually manage digital credentials, sessions and claims for authentication, rather than establishing real-world identity, legal personhood, or government-backed proof. xString Tech solutions are grounded in system access credentials rather than proofing a person’s real-world identity. In this context, “OpenID Provider (OP)” refers to authentication and access management, not verification of a person's real-world identity. However, a relying party may leverage successful authentication to initiate its internal Know Your Customer (KYC) process or Know Your Client (KYC) journey.

Hands-on Evaluation

Privacy-Preserving Age Assurance

Proof of Age Digital Certificate (PoADC), powered by xString Tech, transforms how age assurance is delivered online. Instead of platforms estimating a user’s age through intrusive data collection, PoADC provides highly accurate, cryptographically verified proof of age — without revealing personal identity information.

Key Benefits

• Age is assured with high accuracy — not guessed.

• No personal details are embedded within the PoADC.

• Verification occurs independently and cryptographically, without platforms needing to “call home”.

• Eliminates unnecessary collection of sensitive personal data for age estimation.

• No requirement to upload government-issued identity documents to commercial platforms or websites.

• No need for facial image capture or facial scanning simply to prove age.

• Helps reduce exposure to data leaks, identity theft, and unnecessary data retention.

A Privacy-First Approach

PoADC enables platforms to achieve age assurance objectives while helping protect user privacy, security, and digital trust.

Proof of age — not proof of identity.



You will need to download xString Tech myAge app from the Apple App Store or Google Play Store.

Note: This evaluation requires the myAge authenticator app to interact securely with the MAAS application server. The iOS version is currently available on the Apple App Store, and the Android version is being prepared for release on the Google Play Store. Please check back soon for updates.



Minimum Age Assurance System (MAAS)

1. Dedicated MAAS functions and features are available to government agencies, government departments, and social media platforms worldwide for hands-on evaluation and testing. Access requires a specific access key. If you do not yet have an access key, please request one by emailing: accesskey@xstring.tech

2. User-focused functions and interactive self-guided demonstration features are fully developed and operational. Public demonstration access will be progressively expanded based on demonstrated community interest and adoption levels, including growing download activity of the myAge app.

At present, iOS users can already use the myAge authenticator app to sign up and sign in to the xString Tech Member Access Portal without requiring an email address, phone number, or other personal information.
