Upgrading chirpstack changes admin password

When i upgrade to latest version by changing docker-compose.yml from:
chirpstack-network-server:
image: chirpstack/chirpstack-network-server:3
chirpstack-application-server:
image: chirpstack/chirpstack-application-server:3
chirpstack-gateway-bridge:
image: chirpstack/chirpstack-gateway-bridge:3
to:
chirpstack-network-server:
image: chirpstack/chirpstack-network-server:3.12.3
chirpstack-application-server:
image: chirpstack/chirpstack-application-server:3.14.0
chirpstack-gateway-bridge:
image: chirpstack/chirpstack-gateway-bridge:3.10.0
I cannot login using my old admin-password.
I did “docker-compose down” and “docker-compose up -d”
How can i restore the old password ? Or create a new account ?

best regards, Magnus Persson
