Reliable
A user definitely receives 2FA code—Nobody can control or restrict their account. The blockchain verifies OTP delivery.
Secure
Send 2FA codes with blockchain transactions, encrypted with Diffie-Hellman Curve25519, Salsa20, Poly1305 algorithms and signed by SHA-256 Ed25519 EdDSA. Exclude MITM attacks, and guarantee authenticity.
Accessible everywhere
Receive a code on any device—in a browser, or use iOS, Android, Windows, Linux, macOS app. And you can create your own.
Anonymous
Your users remain privacy. No emails and phone numbers. IPs are hidden. The Tor app.
Open-source
Feel free to deploy packages and revise the software code—including Blockchain node, communication protocol and client apps.
Cheap or even free
You pay 0.001 ADM~0.00001 USD for OTP delivery. If you’ll deploy own blockchain based on ADAMANT—then free.
