Thanks OTP.
We’ll take
it from here
Hackable, fakeable, spoofable, swapable:
it’s time to move on from OTP.
BigHen’s authentication solutions extends the broad reach of OTP with a never-hacked physical layer of security. We make mobile authentication safe again.
Favored by financial services, software vendors, MNOs…and hackers
Everyone loves OTP. It’s easy. It has 100% reach. It’s also massively vulnerable to SIM swapping, phishing and interception. It’s time to stop leaving customer identity exposed. It’s time to move on from OTP.

A Strong Layer of Physical Security
Everyone’s got them. Every mobile device (legacy devices, too).
Tablets, PCs, IoT devices…even cars and appliances. The SIM (eSIMs, too) packs a powerful security punch. Now, BigHen turns SIMs into a seamless, yet ironclad, authentication solution, too.
No More
SIM Swap
BigHen is like SIM super glue. We bind unique device and SIM identifiers. And any change in the SIM or device – like SIM swap or phone replacement – is detected, enabling web services to prevent malicious log-ins.
Nothing
To Hack
There’s not much to hack on BigHen's SIM applets. Not much code. No personal data. That’s why even if the SIM-based BigHen applet was compromised, there’s just nothing to steal. Kind of like breaking into a safe…and finding it empty.
Never
Been Hacked
It's true. The SIM has never been hacked. That makes using it (eSIMs, too) for authentication much safer than complex, code-heavy solutions.
100%
Reach
Smartphone, legacy devices, wearables, IoT… BigHen works with any device and any OS.
0%
Friction
No account creation. No app installs. BigHen makes authentication seamless, silent and super easy for end-users.
Simple
Integration
SaaS-based API implementation means you can get up and running on BigHen F-A-S-T, without impacting your existing authentication solutions.
