How to disable "Disk Password" on boot?

Hello everyone!

I am kind of new to the whole Mac computer world so I'm a little lost. I recently (last night) did a fresh install of Mountain Lion on my MBP. Before I did that, I had a login password and another password that was setup for FileVault (I think). During the procedure I formatted my HD journaled and encrypted, and also I was asked for a password. I thought that was going to be the login password but now I realized it was not. Now I everytime I boot/restart my machine I get asked for a "Disk Password" and then I get asked for a "Login Password". I have both passwords since I was the one who set them up (they are the same), but I would like to disable the "Disk Password" since it is a little annoying.

Thank you!

MacBook Pro, OS X Mountain Lion (10.8.3), Early 2011

That first password is because you encrypted the drive. The only way to not have that is to not encrypt the drive and not to use filevault.

Redo your setup and this time don't use the encrypted option and then don't enable filevault. You will then only have one password for your username login.

It's not really clear what you did. Normally with FileVault 2 you only have to enter one password to log in. Does the Security & Privacy preference pane show that FileVault is active?

I performed the same procedure as rehpiaS; Installed Mountain Lion, encrypted disk with FileVault; ended up restoring from TimeMachine and now I have an extra icon at boot screen called "Disk Password". I am researching how to remove this extra icon as I am fairly new to Mac OS/FreeBSD as well but learning all the platform specific UNIX commands as fast as I can 🙂

I realise I reply to a 2 year old post, but just for documentation purposes:

When you install OSX, you normally do not encrypt the drive first. You format it normally and install OSX.

Then when you boot into OSX, you can turn on FileVault. This will then encrypt the entire disk - also the unused space.

If you format your disk encrypted before installing OSX, the format does NOT encrypt your entire drive. But the downside of that method is:

- There might be information on your disk already from the days you were using it unencrypted. This is the reason why turning on FileVault encrypts the entire drive - also the unused space.

- You have a disk password to unlock the drive

When you boot into OSX, you can go to the FileVault settings in the preferences and add the users that are able to logon. That way you can specify 1 password for the user to unlock the boot drive AND login.

But you will have that initial disk password as well.

To fix that, open Terminal and do:

sudo fdesetup list -extended

This will show you the passwords that can unlock the drive.

MAKE SURE THE DISK PASSWORD IS NOT THE ONLY PASSWORD LISTED.

Copy the UUID for the Disk Password and enter:

sudo fdesetup remove -uuid 12345678-1234-1234-1234-123456789012

Replace 12345678-1234-1234-1234-123456789012 with the UUID of your disk password.

Now only the users will be able to unlock the drive.

To verify do another:

sudo fdesetup list -extended
