On a fresh install of neo4j-community-2.2.4 I get the message \"Invalid username or password.\" when submitting the login form at localhost:7474/browser with the default usernam
Since you get an authentication error on your browser request which uses the default credentials neo4j:neo4j your database has already a different password configured. To reset it to default, stop neo4j, delete data/dbms/auth and start it again. Now you can use the default pw.
