AUTH [username] password
Time complexity: O(1)
ACL categories: @fast, @connection
The AUTH command authenticates the current connection. If the
username is omitted, it implies the user
default from ACL. Dragonfly will deny any command executed by the already
connected clients, unless the connection gets authenticated via
If the password provided via AUTH matches the configured password, the server replies with the
OK status code and starts accepting commands. Otherwise, an error is returned and the clients needs to try a new password.
requirepass also changes the ACL default user
Because of the high performance nature of Dragonfly, it is possible to try a lot of passwords in parallel in very short time, so make sure to generate a strong and very long password so that this attack is infeasible.
Simple string reply or an error if the password is invalid.
