What language should I learn to create an authentication website?

[Atman Atos]

The website functions by a user inputting their email address and self-generated password. I am leaning towards node.js. What language will be sufficient to create such an authentication-based website? On the front-end, my skills are HTML, CSS and JavaScript. E.g a user inputs their details, i.e email: (e-mail address removed), and password: examplePassword, then they are able to access the next page if the details entered match those used to sign up. Thanks

My preference for server-side coding language and storage would be PHP and MySQL
The code and DB set up can be found in a number of places here are a couple:

and

P.S.
Don't forget to also include the register section.
