Cotter React Native SDK

npm version

Cotter's React Native SDK makes it quick and easy to build secure passwordless login using email or phone number in your Android app. We provide a full-suite authentication that includes SSO for email or phone number secured with the FIDO protocol.

Get started with our 📚 integration guides and example projects.

How to use the example app

The example app uses a mock backend that we create for testing. It gives API endpoints to register and login users. If you want to delete a user, go to and enter the email you want to delete from the mock backend DB.
