Password..

Welcome to Eorzea!

In regards to your first issue, that's just an IP address block, it's usually caused by your computer's/PS3's IP address changing each time you connect to the internet. Unfortunately the only way to avoid this is to purchase a security token with your account, as otherwise your account will be constantly locking each time your IP address changes.

As for your second issue, to change your password, you need to access the Square Enix Account Management System, not the Mogstation, which can be found here: https://secure.square-enix.com/accou...n?cont=account - after logging in, your password can be changed under 'Update Account Information' on the menu on the side, and click 'Update Password' on the next page.

Hopefully this has helped!
