When you first create a Neo4j AuraDB database through the Aura console, the system will generate a random password (Generated password). It is imperative that you copy and preserve this password in a safe location as it will not be displayed again.
Neo4j Aura Support are unable to recover or reset a database password for you. It should be noted that Neo4j personnel will never request your password for any reason.
Should you lose your initial password that was provided when your Neo4j Aura database was created, you should download the latest database dump (Export) and load it database to another AuraDB instance to be able to use it.
Alternatively if you had created other than the default neo4j user accounts at database level (not the Aura console) you could reset the password following the methods described here.
