One endpoint to implement
Your application receives the standard OAuth response and verifies the sign-in. A custom call also returns the user's name, user secret, and client user secret when your application needs them.
Implement one endpoint. Let us handle the rest of sign-in.
Software KC OAuth is a hosted OAuth provider for developers. Your application implements a single endpoint that confirms a user has signed in. Registration, passwords, two-step verification, and login providers are handled for you.
What's included
Authentication without building authentication.
Login methods per application
Choose what each application allows: Google, Microsoft, built-in user name and password, or any other OAuth provider, such as Apple or Meta, configured as a custom provider.
Your configuration, your keys
You supply your own API keys and settings for each login provider, so the connection to Google, Microsoft, or anyone else is under your accounts.
Passwords and two-step verification
For user name and password sign-in, passwords are always stored hashed, and users can turn on two-step verification with an authenticator app (TOTP).
Several accounts at once
Users can stay signed in to more than one account at the same time and switch between them, the way Google and Microsoft products work.
Your users stay yours
User accounts belong to your subscription, separate from every other subscriber's. User information is encrypted at the user level, so our staff can't read it.
Built by Software KC
The same sign-in we use for our own products.
Software KC OAuth is part of the platform our own products run on, alongside organization management and subscription management. One account signs people in to all of our products, and it's the same foundation we build on for our clients.
