Unraid Docker-Changing MYSQL Database Password

I installed and setup Nextcloud docker on my Unraid NAS and used the MariaDB docker for the database. All was peachy. Today I had an issue requiring me to reinstall both dockers but I likely did not use the same password on the MariaDB docker during setup (I forgot the password so I guessed which one I used). How can I change the password on Nextcloud so it has access to the database?

If I need to clarify any information or I did not add needed information I apologize and will correct it ASAP.

Many thanks from a new community member.
