I installed Magento locally using the Bitnami Magento stack and during the installation I setup user/pass, only once which is good to login into the admin area. I tried to used in phpMyAdmin but it won't work.
Any workaround on this? Thanks.
Please you take a look to the Bitnami Magento Installer documentation:
https://docs.bitnami.com/installer/apps/magento/#how-to-access-phpmyadmin
You should be able to access phpMyAdmin directly, by browsing to http://127.0.0.1/phpmyadmin.
The username is root
for phpMyAdmin, and the password is the one specified by you during the installation process.
I hope this information is useful for you.
