You can get the password information from the MySQL's database and edit it in case you need it. Let's do that!
- Access the instance and run the following command. It'll ask you for the MySQL's root's password but it's the same one than the one we configured when launching the instance.
mysql -u root -p -e "select id,email,password from bitnami_joomla.jos_users"
This command will return the email of the different users, their ids and the password (a md5 hash). In case you want to change the password of one of those users:
- Get the id of the user
- Get the md5 hash of the string you want to use
- Access the instance and run this command
mysql -u root -p -e "update bitnami_joomla.jos_users set password='MD5_HASH' where id='ID_OF_USER'"
You will be able to access Joomla using that password.
