Globus provides logins for NeSI users via Google and GlobusID.
If you will generally access Globus through Google, the recommended route to setting up your Globus account is:
1) Sign-Up using Google - this then becomes your primary identity in Globus
Log in to https://globus.org using your google identity:
2) Link other Globus identities to your primary identity
From the Globus docs:
Login to a Globus account, via its primary identity or one of its linked identities, implies login to the account’s primary identity and all identities linked to that account’s primary identity. In other words, login to a Globus account potentially grants access to all resources accessible via all identities linked to that Globus account’s primary identity.
If you have other identities in Globus (for example, a globusID), link them to your Google ID account following the instructions at https://docs.globus.org/how-to/link-to-existing/:
Note:
If you had a Globus account before February 2016, that account ID is now your "GlobusID".
Your groups and data-shares are associated with your login so you should ensure that your primary identity is the login you will generally use.
