Implement in minutes

The OnlyAuth Platform works via an embeddable widget. Simply grab your API credentials, use the provided code to generate a JWT token, and then pass that JWT  to the OnlyAuth Widget and from there OnlyAuth will take care of the entire Two-Factor process for your users.

Responsive widget whether it's a web app or a native mobile app

Simply pick which channels you want to support via a simple config change - takes just seconds

Don't rely on just a single channel

Despite the popular use of OTP (One Time Passwords) via SMS, it can be insecure, and attacks are growing at an alarming rate. TOTP (the QR Codes you need to scan), while offering much more security, can be quite cumbersome for non-technical users to use. OnlyAuth is the only option that supports it all, while giving your users more secure options, and less overhead for you to operate.

Support for many available channels -- allowing your customers to pick what is better for them
