I think it's important to get the terminology and function of the
various programs correct so that there's no confusion.

Seahorse is the Gnome frontend for managing passwords, encryption keys
and so on.  It does not store any information itself, it's just a
frontend.

gnome-keyring is the backend daemon that stores passwords and keys (and
other things).  Various applications use gnome-keyring to securely
store information - evolution is one of those. (Well, technically,
evolution uses libsecret that in turn uses the DBus Secret Service API
that allows any backend store, but gnome-keyring is currently the only
one that provides it.)

Running seahorse will start gnome-keyring if it isn't already present.
It is the presence of gnome-keyring that is important, not the presence
of seahorse.

Gnome login will automatically start gnome-keyring and unlock the
default/login keyring. You can do the same thing for other desktop
environments by setting up PAM correctly. Note this only works if the
login password is same as the default keyring password.  If the
passwords are different or the login password is not available (i.e. if
you start it outside the login process) then you will be prompted for
the password.
