I want to Import a modified Magento 1.9 Export of the Customers. But my first little test showed, that the password Hashes seem not to work is the new Magento, the User import worked but the password is said to be wrong when try to login.
Cant I migrate this password hashes?
As you might know, Magento 2 uses a different encryption model from Magento 1. It uses a new technique of hashing passwords sha256(), while Magento 1 uses md5() which produces hash values of length n=128.
However, it should be noted that Magento 2 still supports both old md5() and sha256(). That means you can have both password_hash in your Magento 2.
You can manually upgrade your password_hash using md5() to sha256() after migration by running the command: php -f bin/magento customer:hash:upgrade.
Another method that you could consider is using an automated migration tool, which can transfer your customer passwords and other data quickly and accurately.
Let me know if you need further assistance. Hope it helps!
