I’m in the process of moving Magento store into WooCommerce.
The problem is that Magento and WordPress has different password autentificacion algorithm.
The way magento store the password: md5($salt.$password).':'.$salt;
The way WordPress store the password: md5($password)
Is there way to export existing Magento customers into worpdress and keep their passwords ?
Since that is a one way encryption that would not be possible. Your best bet would be to modify the WordPress store to use the same encryption used by Magento.
This might be a very old post, but have found the following solution:
https://wordpress.org/plugins/magento-user-compatibility/
Its a plugin that, upon login, tests the entered password against the Magento hash, if that is successful, it re-hashes the password WordPress style and saves that to the database and proceeds with login.
