GNOME Online Accounts provides interfaces so that applications and libraries in GNOME can access the user's online accounts. It has providers for Google, Nextcloud, Flickr, Foursquare, Microsoft Account, Microsoft Exchange, Fedora, IMAP/SMTP and Kerberos.
GDM, the GNOME Display Manager, handles authentication-related backend functionality for logging in a user and unlocking the user's session after it's been locked. GDM also provides functionality for initiating user-switching, so more than one user can be logged in at the same time. It handles graphical session registration with the system for both local and remote sessions (in the latter case, via the XDMCP protocol). In cases where the session doesn't provide it's own display server, GDM can start the display server on behalf of the session.
GNOME Initial Setup is an alternative to firstboot, providing a good setup experience to welcome you to your system, and walks you through configuring it. It is integrated with gdm.
