/var/lib/docker/volumes/portainer_data/_data/ This path is needed when using the reset command.

3. Reset Password#

docker run --rm -v /var/lib/docker/volumes/portainer_data/_data:/data portainer/helper-reset-password # Replace source address

docker run --rm -v /var/lib/docker/volumes/0e304ccd0c1c26495c60e458a02997f0568719b6df8388ae82418915d11cad9e/_data:/data portainer/helper-reset-password # Local address

Portainer login address http://IP:9000, username admin, password is the long string of characters after the reset.
