I am trying to utilize Neo4J in either R or Python. I have downloaded Version 4.2.1 and I know that for the neo4r package that I need to use an older version of Neo4J like 3.5.x. I have followed someone's instructions to change the version when I add a DBMS. However, I am unable to find the password or change the password. Every time, I use "neo4j" or "password" as the password I receive errors such as "Database failed to create: Error: Could not change password" or that "Database failed to create: Error: DBMS with name "Graph DBMS c9db202c" already exists". Can you please help me?
if this is 3.5.x then either
a. username/password details are recorded on the file system at $NEO4J_HOME/data/dbms/auth file. Simply delete/rename said file and on startup it will recreate the file with a default username/password of neo4j/neo4j
b. disable authentication by editting $NEO4J_HOME/conf/neo4j.conf and set dbms.security.enabled=false and then restart Neo4j
