Every time I log on my mac asks me messages agent wants to use my keychain, How can I get rid of it?

You may need to open up Keychain Access from the Utilities folder and reset the default login keychain. Be aware this may mean you need to re-enter all your passwords at least once so they are remembered. It will be under Keychain Access -> Preferences -> Reset my default keychain.

I don't think you want to RESET your keychain (which will probably dump all your passwords). I think you want to grant access for that Application to be able to access your keychain automatically. The procedure is a little complicated:

OS X Lion: Allow applications to access your keychain

In addition to the other's suggestions, review the following to determine if it is applicable: Mac OS X: Keychain Access asks for keychain "login" after changing login password.

Back up all data.

Launch the Keychain Access application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.

Select the login keychain from the list on the left side of the Keychain Access window. If your default keychain has a different name, select that.

If the lock icon in the top left corner of the window shows that the keychain is locked, click to unlock it. You'll be prompted for the keychain password, which is the same as your login password, unless you've changed it.

Right-click or control-click the login entry in the list. From the menu that pops up, select Change Settings for Keychain "login". In the sheet that opens, uncheck both boxes, if not already unchecked.

From the menu bar, select

Keychain Access ▹ Preferences ▹ First Aid

If the box marked Keep login keychain unlocked is not checked, check it.

Select

Keychain Access ▹ Keychain First Aid

from the menu bar and repair the keychain. Quit Keychain Access.

same problem.. seems that Link Davis way solve the issue.. thank You, crossing fingers..🙂

So I just started experiencing this last night.

I've opened up Keychain Access and selected the option - Change Settings for Keychain "login", but it just freezes :(

Tried rebooting again but just the same.

Why hasn't Apple released a bug fix for this??!

Probably because you are the only person experiencing this problem.

Oh really Grant, seems that over 300 people have complained about keychains recently on the Apple forums alone, already.

Anyway, I was able to fix it by following what Steve said here:

https://discussions.apple.com/thread/5521104?answerId=23768561022#23768561022

P.S. This is for the "local items" login promt, not the "login" keychain promt (which would be the fix above).

(I've edited the orginal to this)

1. Go to Finder

2. Look for the hidden folder Library, ie: /Users/clarebear/Library/Keychains.

3. Inside the Keychains folder is a single folder with random numbers and letters, ie: ACE4BDA3-B48C-5F97-AEB0-3836B9E48457

4. Drag this folder onto your desktop.

5. Re-boot and you should be good to go.

6. If Ok drag the folder off your desktop into the trash!!

Only thing that popped up when rebooting was icloud asked for my password, so I entered it and it went away.

Problem solved.

Deleting the hidden folder a la clarebear's suggestion above did the trick for my "local items" problem.

clarebear's suggestion worked for me for a few hours and then the messages about keychain started again. I am using retina MacBook Pro.

I had this problem too. Keychain first aid didn't fix it for me. I found this to be very annoying because I don't and never have used the Messages app, so I don't know why it would be asking in the first place for my keychain password.

But I was able to fix it by making the passwords for the keychain and my user account login the same. That prevented the Messages app from asking for it at login.

I tried everything suggested here and many other things to fix this same issue, that started when I migrated to a new Mac. Nothing worked. Then I remembered that I used a different the account login password when I set up the new Mac. Once I changed the new Mac's login password to match the old one, the messages stopped. I'd still like to have the ability to change my login password, but this stops the madness for now.

That's a nice solution if you don't care about leaving your default keychain open, providing full access to its contents.

I prefer to use a dedicated "open" keychain for that, one that only gets locked when you suspend the system but otherwise remains open and only contains less-sensitive passwords. But for that to work you need to know which entries an application needs to have access to, in order to transfer them from the default keychain to the open keychain.

So, specifically, what is or are the keychain entries that the Messages Agent needs to access to?

I raised this issue in another thread (what is the "messages agent" i am asked to sign into every time i turn on my Mac?) and got no response there.

Maybe the answer for those of us concerned about leaving a keychain unlocked all the time, is to make "login" the open keychain, and put our sensitive information in another keychain that does not stay unlocked. I don't know what the Messages Agent is, but I don't think I've given it any sensitive passwords. I'm going to try this.

I am having the exact same problem as well!
