One tap. Your SIM card generates a cryptographic proof that no phisher can steal. Try it — no login, no app install, works right here.

Under the hood
What just happened
01
Device signals detected
VerifyOS reads carrier metadata from the active SIM — ICCID prefix, MCC/MNC codes, and network type. No phone number is required.
02
Silent carrier API call
A request is sent to your carrier's authentication endpoint over the mobile data channel — never over Wi-Fi, ensuring the SIM is physically present.
03
Cryptographic proof issued
The carrier signs a timestamped token with the SIM's private key. The resulting proof is scoped to this session and expires in 60 minutes.
04
Shareable & verifiable
The proof URL can be forwarded to your security team. Anyone with the link can verify the cryptographic signature without re-authenticating.
