+# Setting Up Authentication
+
+Dozzle supports a very simple authentication out of the box with just username and password. You should deploy using SSL to keep the credentials safe. See configuration to use `--username` and `--password`. You can also use docker secrets `--usernamefile` and `--passwordfile`.
