 - Per-user authentication methods.
 - [Two-factor authentication](./docs/howto/two-factor-authentication.md) based on time-based one time passwords (RFC 6238) which works with Authy, Google Authenticator, Microsoft Authenticator and other compatible apps.

 - Simplified user administrations using [groups](./docs/groups.md).
 - [Roles](./docs/roles.md) allow to create limited administrators who can only create and manage users with their role.
 - Custom authentication via [external programs/HTTP API](./docs/external-auth.md).

@@ -138,9 +138,9 @@ The configuration file contains the following sections:
   - `banner`, string. Identification string used by the server. Leave empty to use the default banner. Default `SFTPGo_<version>`, for example `SSH-2.0-SFTPGo_0.9.5`
   - `host_keys`, list of strings. It contains the daemon's private host keys. Each host key can be defined as a path relative to the configuration directory or an absolute one. If empty, the daemon will search or try to generate `id_rsa`, `id_ecdsa` and `id_ed25519` keys inside the configuration directory. If you configure absolute paths to files named `id_rsa`, `id_ecdsa` and/or `id_ed25519` then SFTPGo will try to generate these keys using the default settings.
   - `host_certificates`, list of strings. Public host certificates. Each certificate can be defined as a path relative to the configuration directory or an absolute one. Certificate's public key must match a private host key otherwise it will be silently ignored. Default: empty.
-  - `host_key_algorithms`, list of strings. Public key algorithms that the server will accept for host key authentication. The supported values are: `[email protected]`, `[email protected]`, `[email protected]`, `[email protected]`, `[email protected]`, `[email protected]`, `[email protected]`, `[email protected]`, `ecdsa-sha2-nistp256`, `ecdsa-sha2-nistp384`, `ecdsa-sha2-nistp521`, `rsa-sha2-512`, `rsa-sha2-256`, `ssh-rsa`, `ssh-dss`, `ssh-ed25519`.

If set and valid, `diffie-hellman-group-exchange-sha256` and `diffie-hellman-group-exchange-sha1` KEX algorithms will be available, `diffie-hellman-group-exchange-sha256` will be enabled by default if you don't explicitly set KEXs.
