Still, some users may wish to log in as MariaDB root without using sudo.

PWSAFE OPENS SLOWLY PASSWORD

And if you want to script some tedious database work, there is no need to store the root password in plain text for the script to use (no need for debian-sys-maint user). But not asking for a password means, there is no root password to forget (no need for the numerous tutorials on “how to reset MariaDB root password”).

It is based on a simple fact that asking the system root for a password adds no extra security - root has full access to all the data files and all process memory anyway. This technique was pioneered by Otto Kekäläinen in Debian MariaDB packages and has been successfully used in Debian since as early as MariaDB 10.0. Using unix_socket means that if you are the system root user, you can login as without a password. They are created as: CREATE USER root localhost IDENTIFIED VIA unix_socket OR mysql_native_password USING 'invalid' CREATE USER mysql localhost IDENTIFIED VIA unix_socket OR mysql_native_password USING 'invalid' Two all-powerful accounts are created by default - root and the OS user that owns the data directory, typically mysql. And installation scripts will no longer demand that you “PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER !”, because the root account is securely created automatically.

MariaDB 10.4 adds supports for User Password Expiry, which is not active by default.Īs a result of the above changes, the open-for-everyone all-powerful root account is finally gone.

Previously root was the definer, which resulted in privilege problems when this username was changed. From MariaDB 10.4.13, the dedicated mariadb.sys user is created as the definer of this view. Tools that analyze the er table should continue to work as before. The er table still exists and has exactly the same set of columns as before, but it’s now a view that references the mysql.global_priv table.

All user accounts, passwords, and global privileges are now stored in the mysql.global_priv table.

Remember, the best way to keep your password safe is not to have one! You may want to try going without password authentication to see how well it works for you.

However, just using the unix_socket authentication plugin may be fine for many users, and it is very secure.

However, an invalid password is initially set, so in order to authenticate this way, a password must be set with SET PASSWORD.

Second, if authentication fails with the unix_socket authentication plugin, then it is configured to try to use the mysql_native_password authentication plugin.

This allows the user to login without a password via the local Unix socket file defined by the socket system variable, as long as the login is attempted from a process owned by the operating system root user account.

First, it is configured to try to use the unix_socket authentication plugin.

The user account created by mysql_install_db is created with the ability to use two authentication plugins.

For example, this can be useful to slowly migrate users to the more secure ed25519 authentication plugin over time, while allowing the old mysql_native_password authentication plugin as an alternative for the transitional period.

It is possible to use more than one authentication plugin for each user account.

There are four new main features in 10.4 relating to authentication:

Altering the User Account to Revert to the Previous Authentication Method.

Reverting to the Previous Authentication Method for Configuring mysql_install_db to Revert to the Previous Authentication Method.
