MySQL 8.0 has introduced an optional behavior that authorize users to change their password only if they could provide the current password.
MySQL provides password-expiration capability, which enables database administrators to require that users reset their password.
MySQL has the capability of generating random passwords for user accounts, as an alternative to requiring explicit administrator-specified literal passwords.
My DBA told me that an account I use to talk to my MySQL database instance has TWO passwords! How does that happen? Do I have to provide both passwords every time?
A Confused User Who Does Not Want to Type Two Passwords All The Time
Dear Confused User,
Dual Password Support was added in MySQL 8.0.14 and it is a very handy thing. User accounts can now have a primary password and a secondary password. Image a scenario where you are rotating passwords as directed by your company policy but it takes a while to change the credentials in all your code despite your best EMACS magic. The ability to keep the servers up and active as your do your security due diligence is very helpful.

One of Oracle's tenets is the focus on security. For this reason, when it took over the stewardship of MySQL, it started addressing the most common issues. It was not quick acting, but we have seen real progress:
- MySQL 5.7 has removed the anonymous accounts, which was the greatest threat to security. Because of those accounts, and the default privileges granted to them, users without any privileges could access the "test" database and do serious damage. Additionally, because of the way the privilege engine evaluates accounts, anonymous users could hijack legitimate users, by preventing them to work properly.
- The "root" account now comes with a password defined during …
Have you ever forgotten your WordPress administrator password and did not have access to your e-mail account or haven’t configured ...
What is the solution if I don’t want to give password in command line (i.e mysql -uroot -p ) OR don’t want to store password in files(in .my.cnf) and still can login into MySQL/MariaDB without password ? I was also bit curious to know but finally I found very easy solution called “unix_socket plugin” provided by MariaDB.
This plugin allows to use operating system user credentials while connecting to MariaDB via Unix socket. When we try to connect with OS user, it will retrieve uid of the process which has connected to the socket and allow it to connect to MariaDB with the same user.
You can simply install that plugin with command,
MariaDB [(none)]> INSTALL PLUGIN unix_socket SONAME 'auth_socket'; Query OK, 0 rows affected (0.02 sec)
After, then you need to identify the user which you want to use to login into MariaDB. Like for me,
MySQL 5.7 introduced many new facets to password security. The first thing most notice is that you are assigned a random root password at installation time. You then have to search the log file for this random password, use it to login, and then change it. For the examples on the post I am using a fresh install of 5.7.13 on Oracle Linux 7.1 and was provided with the easy to remember password of nLvQRk7wq-NY which to me looked like I forgot to hit escape when trying to get out of vim. A quick ALTER USER to change the password and you are on your way. Defaults Password Lifetime and Complexity5.7.13 now has the default password lifetime set to 0 or 'never expire'. My fresh install shows that the value of mysql.user.password_lifetime is set to NULL which …[Read more]
