Disable registration and (optionally) invitations
By default, bitwarden_rs allows any anonymous user to register new accounts on the server without first being invited. This is necessary to create your first user on the server, but it's recommended that you disable it in the admin panel (if the admin panel is enabled) or with the environment variable to prevent attackers from creating accounts on your bitwarden_rs server.
bitwarden_rs also allows registered users to invite other new users to create accounts on the server and join their organizations. This does not pose an immediate risk (as long as you trust your users), but it can be disabled in the admin panel or with the environment variable.

Disable password hint display
bitwarden_rs displays password hints on the login page to accommodate small/local deployments that do not have SMTP configured, which could be abused by an attacker to facilitate password-guessing attacks against users on the server. This can be disabled in the admin panel by unchecking the Show password hints option or with the environment variable.

Brute-force mitigation
When two-factor-authentication is not in use, it is (in theory) possible to brute-force user passwords and thus gain access to their account. One, relatively easy, way to mitigate this, is setting up fail2ban which blocks ipadresses after too many failed login attempts. However: Care should be taken when using this behind multiple reverse-proxies (such as cloudflare). See: Fail2Ban Setup
