Cannot get phpmyadmin to work

hİ, update came. try this https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-phpmyadmin-on-ubuntu-18-04

i am also facing this issue.

I have install phpmyadmin by this tutorial - https://www.digitalocean.com/community/tutorials/how-to-install-and-secure-phpmyadmin-on-ubuntu-18-04

But now when i login in to example.com/phpmyadmin with username as root and password found in (cat .digitalocean_password) it give me error mysqli_real_connect(): (HY000/1045): Access denied for user ‘phpmyadmin’@‘localhost’ (using password: YES) and never let me login.

On other hand when i try login with username “wordpress” and password provided in (cat .digitalocean_password) , i am succesfully logged in.

1. I dont know why it create two username and password (1 is root, 2 is wordpress)
2. when i open wp.config file, there username is wordpress.
3. Now i am thinking that username root does not exist but (cat .digitalocean_password) file show password for root.

What password are you using at the login prompt of phpmyadmin? It needs to be MySQL’s root password. Which if it’s the default one, it’s blank. Make sure you change it to a strong password.
