Password Vault
To create and manage roles in databases, you must have a user who can log in to the relevant databases. You can define this user information here and edit your roles.

Set as default
If you want to use your users in databases and perform operations (for example, creating a new role), this option will connect with the currently active user. If none of your users have this option enabled, the connection will attempt to connect to the database with your first defined user.
Public user
If this option is selected when defining a new user, users can use this user to connect to the database when creating projects. This option is available only to admin users.
