A Magento module to implement a Magento Master Password to allow you to login to any valid customer account with one master password. Created from the code in my Magento Master Password 5 Minute Fix blog.
Tested with Magento eCommerce Community Edition only v1.3 -> 1.9.x
Uses an MD5 hash of the password, master password is never stored in plain text.
modman clone https://github.com/gaiterjones/magento-masterpassword.git
Copy the files to your magento installation folder. Refresh your cache and log out and back into admin. Goto System – Configuration and select My Extensions – Master Password to access the configuration.
Enter your master password in the Create Master Password MD5 hash text box to generate an MD5 hash of the password. Copy the MD5 hash to the Master Password MD5 text box and save the config. Note the plain text password is not saved.
Test by logging into any valid customer account with the master password.
