The Jacobs School of Engineering's primary G Suite domain is eng.ucsd.edu. All user accounts in this domain are of the form email@example.com. We also manage a secondary domain for general campus use by customers outside of Engineering. That domain is cloud.ucsd.edu and user accounts are of the form firstname.lastname@example.org. Accounts in these domains are completely independent of other UC San Diego accounts, meaning that your password in G Suite is not connected to your password elsewhere (Active Directory, TritonLink, business systems, network/Kerberos, etc.). Information on other types of UC San Diego accounts, including how to change the associated passwords, may be found here. Changing your password on these accounts will not change your G Suite password, and vice versa.
Typically, new users in the Jacobs School of Engineering G Suite domain will receive an email message containing username and temporary password information, and instructions on how to connect to G Suite initially. In general to login, open a browser and navigate to any Google site (e.g., mail.google.com) and click on the button or link to sign in. For the username, you should use your full account name (i.e., email@example.com or firstname.lastname@example.org) and the provided password. On your first login, you will need to accept the EULA and input a CAPTCHA code. You will also be prompted to change your password to a new one of your own choosing. If you have problems accessing your account, submit a support request to email@example.com.

An excellent starting place to find documentation, tutorials, best practices, etc. about G Suite is the G Suite Learning Center. Other, service-specific documentation includes:
