Forgot my login password for macbook air

totally forgot my password to login to my macbook air
Anyone have help?

Now, the fun part if neither of those is the case.
You can also restart the system holding down the Command and R keys, and then from the utilities that open choose Terminal.
In the Terminal window type exactly:
resetpassword
and press return.
In the Reset Password window, choose the user for which you wan to change the password.
Type the new password twice, then do not set a hint, and click Save.
Accept the next dialog that opens, and at the bottom of the Reset Password window Apply.
Then click the apple at the left side of the menu bar and Restart.

Retrieving/resetting my account password for MacBook Air OS X 10.9.4 when FileVault is NOT switched on?

Hey all,
I've encountered a major problem since purchasing my MacBook Air OS X Mavericks 10.9.4. As I was previously using a Pro with an account password that used to work just fine, I decided to simply set the Air with the same credentials. However, the password I have no recollection of changing is not accepted by my Air. Without it I cannot install any new software and I need several programs urgently. Trouble is, my FileVault is not switched on nor can it be switched on. I cannot reset the password either, as doing so requires me to type in my current one.
What do I do?
Kind regards,
Elena

If you're not using FileVault 2, then FileVault 2 is not involved. Either use your Apple ID to reset your password, or Method 1 here should get your password reset to one you know.

How to reset the admin password for Mac OSX 10.5.8

I have a 2008 Macbook Leopard version of the Mac OSX 10.5.8. My DVD optical drive does not open, and I need to reset the admin password because we have forgotten what it is. Wondering if it is possible doing it at home some step by step process I am fine with deleting all the contents saved on the macbook as well.

Not without the optical drive. You would need to insert the install disc to reset the admin password.

How to reset user and password on MacBook Pro without CD

I recently bought a MacBook Pro, 15" with Lion on Ebay.
There are times when I am asked for a password. I have asked the person who I bpught it from, but he does not remember.
I do not have the original disk, so I need a method to reset the user and password.
Thanks

Thank you for your input.
I received an e-mail from a computer tech that thought the following would work; please let me know what you think:
ResetLion password with Single User mode
Anyone running Mac OS X Lion cantake advantage of this method:
Shut down your Mac and turn it back on while holding     down the Command and S keys at the same time until your see     a black screen with white text. This is known as Single User mode.
You can skip this step, but it’s recommended that you     don’t because it will check the consistency of your hard drive. At the     prompt, type fsck -fy and press Enter.
Once the disk check is complete and the prompt returns,     type mount -uw / and press Enter.
Type launchctl load     /System/Library/LaunchDaemons/com.apple.opendirectoryd.plist and press     Enter.
Type ls /Users and press Enter. All of the     usernames on the computer will be listed, which is helpful if you don’t     know or remember what these are.
Type dscl . passwd /Users/username password     while replacing username with one of the users displayed in     the previous step and replacing password with the new password     of your choice. Press Enter. You will likely get an error message about a     file or directory not being found – it’s safe to ignore this.
Type reboot and press Enter.

Reset SAP GUI passwords for number of users one time

Dear,
i need your help in how to Reset SAP GUI passwords for number of users one time, as we have non-SAP users, only ESS users that they are currently using Portal ESS, but we need to reset thier GUI passwords so that they will not be accessing the GUI.
we need to do it one shot, one time for more than 600 users.
is there any way?
thank you

You can also create an ABAP program which can be used to do a mass user password change.
Here are the functions that will do what you need
SUSR_GENERATE_PASSWORD - Generates a Password. Use this function only if you want to do random passwords. Otherwise you can upload your own password.
BAPI_USER_CHANGE - You can use this BAPI to change just the password of a user
Here is an example of some abap code. There may be some syntax errors and possible other issues. I just typed this out and didnt check it. You upload a comma delimited file which is the username,password. If the password field is blank the program will generate its own. Hope this helps
