OnlyAuth
The 2FA API/Platform for Developers & Enterprises to quickly add and scale Two Factor Authentication
We believe in a future where users can decide how much security they want to add to their accounts (hello back accounts - let me authenticate with my password, and then a touch of my Yubikey). There are better channels than just SMS and Authenticator apps as well - be it biometrics, FIDO security keys, push notifications, Passkeys and more.
OnlyAuth is an API that is built for developers to quickly add these 2FA channels, and allow their users to authenticate 2FA (or even MFA) in channels that work best for them. Meanwhile it's easy for developers to add, maintain, and scale two-factor authentication in their apps.
