All my passwords just dissapered

[Crzyrio]

I noticed that Safari wasn't filling in any of my login information, at first I passed it off as a glitch and figured it would work again in a day or something.

1 week later still, I went and checked Preferences and it's all gone
I can't think of how, all of them are gone. I don't even think there is any way to clear all of them?

I haven't reset safari or cleared its history. Only thing I can think of that happen was:

Running some long Calculations in MATLAB, so left my computer for 2 hours. I came back and it looked like the computer has restarted.

The past 2 weeks I also had a weird screen issue where, it wouldn't turn on. I had to had power boot but not reason either of these situations should result in my passwords dissparereing?

Any idea? Way to retrieve passwords? I had a lot of them there

My best guess is that unless you have Malware of some sort that could erase your browser passwords and I don't know of any someone used your laptop to browse while it was in MATLAB and they erased the history (including passwords) which is an option in Safari preferences > Privacy > Clear all website Data. Someone unfamiliar with Mac Safari could easily do this trying to cover their tracks. As for getting them back you can't unless you have Safari ticked in iCloud services or use iCloud Keychain. Personally I use another browser, copy my data, sites, bookmarks, passwords etc. to that so that if either one looses a site or password the other still has it and it can be synced back. I don't suppose you have a backup?

I should also say that if someone could access your computer and your site passwords they could now have access to all of your sites and their respective passwords.
Your computer should have been in display sleep mode (this doesn't stop the processor from working if it is set not to in Energy Saver preferences) so the only way anyone could gain access would be with your admin password.
If you feel that has been compromised I would advise changing it as well as the passwords for any other sites that were in your browser.
Also it would be worth checking for your login passwords in the KeyChain Utility.

Checking Keychain Access would indeed be a good idea. Don't you have a backup of your system, such as Time Machine?

Thanks! Did not think about that, just checked my iPhone and all the password are still there on my iPhone.

I dont think, my computer was compromised but it is possible.
Something else I noticed yesterday as well:

In my finder window, on the left side where shortcuts are usually there such as 'Desktop', Documents, Pictures etc. It was completely blank and just shows the Harddrives, I had to re add all the shortcuts.

Using iCloud Keychain would be the easiest way to transfer them. I don't know if it is possible to extract them from your iPhone manually.

If there are other irregularities, then I would recommend you do a first-aid operation with Disk Utility on your hard drive to see whether everything is alright with your storage.

Did you have iCloud Keychain sync turned on? It sounds like you did since you are seeing the passwords in your iPhone. On the Mac try going into System Preferences and in the iCloud pane turn off keychain sync then turn it back on. That should pull the passwords saved in iCloud Keychain from iCloud back onto the Mac.
