Neo4j Authentication & Users

Introduction

Authentication in Neo4j is crucial for securing access to your graph database. It ensures that only valid users can access or modify data, thereby safeguarding sensitive information.

Authentication Methods

Neo4j supports several authentication methods:

• Username and Password Authentication
• LDAP Integration
• Kerberos Authentication

Username and Password Authentication

The default authentication method for Neo4j is a simple username and password scheme. To create a new user and set a password, you can use the following command in the Neo4j Browser:

CREATE USER username SET PASSWORD 'securepassword'

User Management

User management involves creating, updating, and deleting users, as well as assigning roles and privileges.

Creating a User

CREATE USER newUser SET PASSWORD 'newPassword' CHANGE NOT REQUIRED

Updating a User

ALTER USER newUser SET PASSWORD 'updatedPassword'
