Why doesn't mysql password work in terminal?

Question

linux

Good afternoon.
Installed mysql using the following instructions.

sudo apt install mysql-server
sudo mysql_secure_installation

And set the root password.

Interestingly, in the terminal I could enter mysql without a password, but I could not enter the workbench.
To do this, set the root password.

Add password for the root to work with workbench
sudo mysql -u root
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Serii1981;';

And now with the help of this password I can connect to the workbench.
But now I can't access mysql in the terminal.

[email protected] ~/Documents/-Knowledge-base $ sudo mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

What is going on?
Help me figure it out.
Thanks in advance.
