Project-GC uses the Geocaching Live API for user authentication. With this you can use your account to login to this site.

You are actually not sending your login information to this site, when you press the Authenticate button below you are redirected to where you will be asked to authenticate this site. When you press the Allow button, you will allow Project-GC to fetch some of the information bound to your account. For example, your home coordinates. This data will be used in accordance with the API License Agreement.

You can at any time you want, revoke Project-GC its rights to fetch your data by visiting Authorizations.

The authentication used by the Geocaching Live API is based on a standard called OAuth2. This is the same technology that is used by Facebook and Twitter to allow other sites/applications to access accounts. Read more about OAuth2 here, or check out the Wikipedia page for easier reading.

By authenticating you are accepting our Terms of Service and Privacy Policy.
