- Usage:
-
AUTH [ username ] password
- Complexity:
- O(N) where N is the number of passwords defined for the user
- Since:
- 1.0.0
The AUTH command authenticates the current connection using the Valkey ACL system.
The standard way to AUTH is the two-argument form:
AUTH <username> <password>
This authenticates the current connection with one of the users
defined in the ACL list (see ACL SETUSER and the official ACL guide for more information).
When the single argument form of the command is used, where only the password is specified, it is assumed that the implicit username is "default".
AUTH <password>
This form authenticates against the "default" user's password set with requirepass.
If the password provided via AUTH matches the password in the configuration file, 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.
Security notice
Because of the high performance nature of Valkey, 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.
A good way to generate strong passwords is via the ACL GENPASS command.
