Singapore's mobile operators M1, Singtel and StarHub have agreed to adopt the GSMA's Mobile Connect authentication standard for universal secure mobile-based authentication.
The three operators are building a unified platform to enable integration with online service providers using a common API.
Once implemented, the functionality will allow Singapore consumers to create a universal trusted digital identity for access to compatible telecoms, banking, e-commerce, entertainment and travel services.
For online transactions that require greater levels of security, consumers will also be provided with a unique personal code.
GSMA research indicates that 87% of consumers leave a website when asked to register, and many face difficulties remembering a growing list of usernames and passwords, with 40% using a forgot password feature monthly.
Implementing the single sign-on functionality therefore also benefits online service providers, which the research suggests stand to improve page views by 67% and likelihood to purchase by 48%.
The first online services that support the operators' new authentication function are expected to launch in the second half of next year.
The GSMA's Mobile Connect is currently available in 22 countries, including China, Indonesia, Malaysia, Bangladesh and Sri Lanka.
