I lost my password, how do i recover my back-up from my computer (itunes)s

I lost my password, how do i recover my back-up from my computer (itunes)?

If you forgot the passcode for yur encrypted backup you are out of luch. You will have to restore the iPod to factory defaults/new iPod if you want to restore from backup in the future.
Warning: If you encrypt an iPhone backup in iTunes and then forget your password, you will not be able to restore from backup and your data will be unrecoverable. If you forget the password, you can continue to back up and use the device, however you will not be able to restore the encrypted backup to any device without the password. You do not need to enter the password for your backup each time you back up or sync.
If you cannot remember the password and want to start again, you must perform a full software restore and when iTunes prompts you to select the backup from which to restore, choose set up as a new device.

Lost Firmware Password - How to reset Firmware in G4 PowerBook

Hi there,
My OS is 10.5.4 but this might be a little off-topic and if so, my sincere apologies.
Several weeks ago, somewhat stupidly, I created a firmware password for my G4 17" PowerBook using a third-party utility but have lost the paper upon which I wrote the password down. The paper is not where I thought I had put it.
Yesterday, completely forgetting that I had a firmware password in place, I had to reformat my HDD and have now discovered that I am unable to boot the PB due to the lack of the firmware password.
My questions are:
1. Does anyone know of a method to reset the firmware to its default state?
2. If not, is the firmware located on the logic board, in which case I can replace the logic board?
3. If not, is the firmware module replaceable or do I have to replace a complete motherboard.
4. Any other possible solutions to this problem?
Many thanks for your help.

Hi V.K.
Many thanks for your feedback. However, I have tried both the OS 10 install disk and the original disk that came with the PB but still get the request for the firmware password on startup. Regretfully, no luck there.
Anyone have any other ideas that might help? All suggestions will be gratefully received and tested.
Cheers
Roger

I lost my password. How can I start my computer?

I lost my password to open my session on the computer. How can I reset to reinitialize it?

This article should help. You will need to jump to the 'Resetting the original administrator account password' section if neither you or anybody else still has administrator access to the system.

Having lost my password, et al., I obtained a new one successfully, but now when I tried to make a purchase, I was asked for my Security Code. How do I obtain a new one since I have lost all my iPad documentation?

Having lost my password, et al., I obtained a new one successfully, but now when I tried to make a purchase, I was asked for my Security Code. How do I obtain a new Security Code since I have lost all my iPad documentation? Thank you, Dzurek123

That refers to the 3 digit security code on the back of your credt card, not a security code for the iPad.

How can I retrieve a lost computer name, needed to log in. I know my Apple ID and password.

Lost computer name, or ID, needed to log in to locked MacBook Pro

If you are trying to log in using a password you can't remember, try booting off the installation DVD and under Utilities you should see an option to reset password.

I have a 2012 mac book pro can I use that to connect with firewire and load osx that way? and how woudl I do that?
Thanks so much!

To what password are you referring? Do you mean your user account's admin password? Or do you mean the master password for File Vault or do you mean a Firmware Password?
For an admin password:
Forgot Your Account Password
For Snow Leopard and earlier
     Mac OS X 10.6- If you forget your administrator password
For Lion/Mountain Lion
    Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
     When the menubar appears select Terminal from the Utilities menu.
     Enter resetpassword at the prompt and press RETURN. Follow
     instructions in the dialog window that will appear.
     Or see Reset a Mac OS X 10.7 Lion Password and
     OS X Lion- Apple ID can be used to reset your user account password.
If you cannot do the above then try this:
1. Boot to Safe Mode by restarting and after the chime press and hold down the COMMAND-S keys until a black screen with white type appears.
2. At the prompt, type the following commands pressing return after each command line:
     /sbin/fsck -yf
     If you do not receive a "Filesystem OK" message then repeat this command until
     you do. If after seven tries you still do not receive a "Filesystem OK" message,
     then the system is corrupted and needs to be reinstalled.
     mount -uw /
     cd /private/var/db/netinfo
     mv local.nidb local.old
     rm ../.AppleSetupDone
     shutdown -r now
The second-to-last command above will cause OS X to think that the operating system is newly installed, and when the new owner starts up the computer it will send him/her to the startup wizard where he/she can start a new user without reinstalling.
This last method does not actually change a password. It simply removes the user accounts and lets you create an initial admin account as if the computer were new out of the box.
How to reset the OS X password without a startup CD:
Reboot into Single-user Mode. Enter the following and press RETURN after each command line
   1. Type fsck -fy
   2. Type mount -uw /
   3. Type passwd <username>
I have never tried this method myself.
