mySQL Security (Avoid mySQL login)

[redhat81]

I have the user mysql running the mysql process (I launch the server by using mysqld_safe --user=mysql &) but I went through conventional steps to create the account (useradd mysql). Is there anyway for anyone to hack into the account since it has no password? If I assign it a password, will it screwup permissions? Is there any way to limit outside access?
