How to use plugins in admin?

Question

MySQL

I need to enter the database without a password, since version 4.6.3 adminer has disabled the ability to enter databases without a password (there is no password set on the database itself)

https://www.adminer.org/en/password/

There are two options, use the plugin
login-password-less

or
login-ip

But I don't understand how to install the plugin

Answer 1

Yes, I'd like to know too.
