Minimize Registration and Log in

In order to provide a unique username and password for all EO services available on the web, ESA has created the Earth Observation Users Single Sign On service, or EO-SSO. You must have an EO-SSO account to access the My EarthOnline functions in Earth Online.

If you already have an EO-SSO account (for example through the EO helpdesk or the eoPortal) you may log on to Earth Online by clicking the 'Login My Earth Online' button at the top of the page. If you are new to Earth Online or do not have an EO-SSO account, please follow the procedure outlined below:

1 – Click "Register" at the top of the page

2 – Fill out the registration form with your prospective account details

Note:The password will need to be composed of at least 8 characters and consist of upper and lower-case letters, numbers, and symbol characters, and should not resemble a word too closely.

3 – Click the "Next" button once the form is complete

Your new account will be generated, and you will shortly receive an automated email asking you to activate this account. Simply click on the link provided in the email, and your one-time registration will be complete.

Note: After you clicked 'next', your browser remains on an EO-SSO page. You must now navigate to the Earth Online home page again ( ) in order to log onto the system for the first time.
