Q: Password reverted to old password automatically!

Hello All,

I changed password on my MacBook Pro running 10.11.3 10 days ago. Since then the MBP updated from 10.11.3 to 10.11.4. The system was updated couple days ago. To log-in the system, the new password was OK until this morning when the system failed to log in. Frantically I tried the old password since I was not sure what else to try. Lo and behold the old password worked. Has anyone encountered this before?

Thanks.

MacBook Pro, OS X El Capitan (10.11.4)

Are you using FileVault? The password for FileVault is separate from your user password.

Maybe in the previous version of FileVault but not in El Capitan. See Use FileVault to encrypt the startup disk on your Mac - Apple Support

I could have sworn I set up a different password when I was playing with FileVault.

I just realized while I was typing the separate password was to encrypt an external drive. It's tough getting old.

Hi!

I use Filevault, however this is the user login password. Filevault password is long enough that I do not bother to remember it.
There is only one user on my computer. I am trying to dig through system logs to understand what might have happened. So far no clue!. This is a major problem and someone in Apple's user security team needs to weigh in (if they read these posts).

Thanks

I have no clue either. I've never heard of it happening.
