I opened my MBP and certainly the system gives the following warning "Cloudd wants to use the "Local items" keychain" and asks me for my keychain-password. After cancelling this warning, it kept coming back, over and over again. After a forced quit and a system reboot the warning was gone.
I never had any idea why my system whould ask for my password at that time, was someone uninvited trying to access my computer? Who or what is Cloudd (double-d)?
That is many questions all in one. In order to manage our search engine, we prefer to have 1 question at the time.
1) I'd prefer Chrome to save the credentials in its own storage, instead sharing one with Safari. 2) If not, I'd rather it to not ask me about that. 3) Failing that, it should at least give me the right credentials.
To prevent the pop up is done with granting the Access Control in the key-chain.
Here is a sample:
Open the relevant key chain item and click on access control.
Add and allow Google Chrome to use it.
In conclusion, TimeMachine recovery of the entire system to the status before changing admin password worked well. I recovered the old admin password and it worked for Keychain Access as well.
In details; Just in case the recovery doesn't work and I lose the TimeMachine backups somehow, I copied the TimeMachine backup to another external drive. To do that, however, I needed admin password. So, first I had to reset the admin password.
Note: In my case, the destination for TimeMachine backup was a local partition (probably), so I didn't need network password to access it. If it were in network, for example, you would need password that has been lost at step 8. Then this procedure may not work for you. Before actually try the following steps, it may be good to see if you need password for system recovery, following http://support.apple.com/kb/PH14185 (step 5 in this page is the key), but just cancel when you are asked to choose date and time.
Time Machine pane in System Preferences. Choose Time Machine > Open Time Machine Preferences…Slide the Time Machine switch to Off.
Restart the Mac with Command + R keys held down to enter Recovery Mode.
Terminal.app.resetpassword.Warning about Keychain will appear.
Restart. Now you get admin password at the cost of loosing Keychain password. The server won't work properly any longer.
The system will ask Keychain passwords, but you have to ignore them.
Connect an external drive that is large enough.
Mac OS Extended (Journaled).
see http://support.apple.com/kb/ht5096Get Info from the File menu or press Command-I (⌘-I)Ignore ownership on this volume at the bottom of the Sharing & Permissions: section is not checked.Backups.backupdb on the current backup drive to the root level of the new backup drive.After the copy has completed, you can eject the eternal drive.
Restart the machine with Command and R keys held down to enter Recovery Mode.
Restore from a Time Machine Backup, then click Continue. Select the date and time of the backup you want to restore, then follow the onscreen instructions.
In my case, I successfully recovered admin password as well as default Keychain password.

It's a private framework made by Apple to interface with iCloud documents and files.
It's safe to allow and there's a possibility of keychain corruption if it won't stick (and since you wouldn't normally get that warning unless the automated process to save your iCloud password has hit a bump like having keychain items deleted or expiring)
