The world is online, and online is mobile. Without the right identity, security and usability both suffer. The beauty of a phone number as the primary identifier for a user is that it is both, possible to link it to a real-world identity, as well as for the owner to prove it in real-time, with a strong proof-of-possession through their SIM card and tru.ID technology. Mobile phone numbers are the most intuitive, convenient, and private identifier for our mobile-first world. It's time to bid adieu to emails.
Adoption of better security means lags due to poor usability. This is why even in 2023, emails and passwords remain the most dominant form of security. Adding SMS based 2FA does little but add unreliable security theatre. Most solutions offering better security make it harder for ALL users to access an identity — requiring one to either carry additional hardware, or treat mobile devices as proxies for identities. Fixing security starts with making it effortless for users.
SMS relies on infrastructure that was not built for speed, reliability or security; it can therefore only add porous security at best. At the other end of the spectrum are FIDO tokens, which are great, but if the identity underlying it can be accessed with mere passwords and an SMS, you're leaving the door wide open. The SIM Card's security, is tamper-proof and this check is verified against directly a user's mobile network operator. Zero false positives guaranteed.
