  1. I hope You don’t keep users passwords in plain text, cause i just got my password back in ‘New Registration’ email message

  2. Hi Panpremier,
    Thanks for your comment. The passwords are sent in plain text for the first time for your records. SG database stores them encrypted with java security MD for password encryption and decryption. So nobody except you would know the password. I hope that helps 🙂
