How can I change InfluxDB admin password in meta.db?

Hello,

I installed InfluxDB using Docker, passed env vars for admin user and password. However, I would like changing the (InfluxDB) password. After some Googling I found out this info is held within the meta.db. What I didn’t found is how can I change my password (in this meta.db)?

Thanks.
Guy
