1. Configure allowed authentication methods. By default, Zulip allows logging in via email/password as well as various social authentication providers like Google, GitHub, GitLab, and Apple. Users can log in with any allowed authentication method, regardless of how they signed up.

2. Invite users by sending out an email or sharing a reusable invite link. Note that on most Zulip servers (including Zulip Cloud), email invitations and reusable invitation links expire 10 days after they are sent.

{tab|allow-anyone-to-join}

1. Allow anyone to join without an invitation.
