No, EF 6 does not ony support Code First. Code first can be a confusing name. It does not mean that you write code and then generate a db from that. You could in fact both target a new or an existing database using code first strategy. Code first simply imply not using the model designer (edmx) to create and maintain your db-context in your development project.
Some links to get you going:
EF 6 Database first (with asp.net mvc)
EF 6 Code first against new db (with asp.net mvc)
EF 6 Code first against existing db
Ps. Worth noting is that EF 7 (Core) will only support the Code First approach (but of course, as in EF 6, against a new or an existing db).

Does Database First uses .edmx files only? – Anubhav Tiwari Jul 01 '16 at 11:15

I have noticed that in Code First Approach there is no .edmx files generated ? – Anubhav Tiwari Jul 01 '16 at 11:15

Yes and Yes, But Code first could be targeted against an existing database (where I thing the naming could be a bit off as it is in fact "database first" and not code first...) But the big point with code first would be that you have Poco classes representing your db/context and with database first you generate the edmx from your database. – Indregaard Jul 02 '16 at 20:39

Yes in Code First the [POCO class](http://stackoverflow.com/questions/16075245/what-is-poco-in-entity-framework) is generated not .edmx file. – Smit Patel Jul 01 '16 at 11:19
