Reset Passwords

mailcow Admin Account

Reset mailcow admin to admin:moohoo. Older mailcow: dockerized installations may find mailcow-reset-admin.sh in their mailcow root directory (mailcow_path).

cd mailcow_path
./helper-scripts/mailcow-reset-admin.sh

Reset MySQL Passwords

Stop the stack by running docker-compose stop.

When the containers came to a stop, run this command:

docker-compose run --rm --entrypoint '/bin/sh -c "gosu mysql mysqld --skip-grant-tables & sleep 10 && mysql -hlocalhost -uroot && exit 0"' mysql-mailcow

1. Find database name

# source mailcow.conf
# docker-compose exec mysql-mailcow mysql -u${DBUSER} -p${DBPASS} ${DBNAME}
MariaDB [(none)]> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mailcow_database   | <=====
| mysql              |
| performance_schema |
+--------------------+
4 rows in set (0.00 sec)

2. Reset one or more users

Both "password" and "authentication_string" exist. Currently "password" is used, but better set both.

MariaDB [(none)]> SELECT user FROM mysql.user;
+--------------+
| user         |
+--------------+
| mailcow_user | <=====
| root         |
+--------------+
2 rows in set (0.00 sec)

MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> UPDATE mysql.user SET authentication_string = PASSWORD('gotr00t'), password = PASSWORD('gotr00t') WHERE User = 'root';
MariaDB [(none)]> UPDATE mysql.user SET authentication_string = PASSWORD('mookuh'), password = PASSWORD('mookuh') WHERE User = 'mailcow' AND Host = '%';
MariaDB [(none)]> FLUSH PRIVILEGES;

Remove Two-Factor Authentication

This works similar to resetting a MySQL password, now we do it from the host without connecting to the MySQL CLI:

source mailcow.conf
docker-compose exec mysql-mailcow mysql -u${DBUSER} -p${DBPASS} ${DBNAME} -e "DELETE FROM tfa WHERE username='YOUR_USERNAME';"
