# Authentication

The Ebury authentication scheme is based on OpenID Connect 1.0, which **[builds on OAuth 2.0](https://openid.net/specs/openid-connect-core-1_0.html)** to make it easier to verify the identity of end users.

Make sure you have received the Welcome email from Ebury with user credentials before you can go through the Authentication process.

Also, the FAQ section on Authentication can give you a few pointers on how to choose which type of user and hence authentication will work for your use use. We have two types of authentication workflows.
