  • M2M and connected apps

    Machine to machine connections combined with connected apps accelerate your product development in the back end and enable powerful product interactions and security.

  • Social and dev logins

    Why make users remember yet another set of credentials? Let them choose how they want sign up and sign in.

Amazing one-liners

Once you have Kinde integrated, it’s just a single line of code to add any feature. And as new features become available, you get them with a snap. That’s developer velocity.

Tiny bundle sizes

Having everything in a single integration, means you’re not shipping the same thing multiple times. This means tiny bundle sizes, smaller downloads – and way faster performance across the board.

Single SDK

Everything you need to integrate Kinde is in a single library. Unified architecture means you integrate only one time. As new features become available, they become available to you also.


Secure by default

We’ll keep you and your users safe. Kinde is built from the ground up using best in class security protocols.
