Keychain will NOT let me reset. It will not let me get my email and keeps asking me for my password. I only have one password and it won't take it. I HATE THIS. It has made my wonderful MAC and expensive item that just sits on desk. PLEASE fix

Here is the fix and it is so easy; I called apple and they fixed it. Go to FINDER and go to GO tab then click the option and a link for LIBRARY will pop up and click it. Scroll to find keychain and put it on your desktop and restart then you should only have to log in one time and then delete keychain off desktop. They said something happened with maverick and it corrupted the Keychain file.

No more passwords when you turn on your computer..

I am having the same issue. It was triggered by restarting my MacBook Air last night. Today I get a flurry of popups asking for my keychain password. I only have one password and the settings are set to synch my login password with my keychain password which obviously is NOT working. I followed the link to the article above and that is not helping. I cannot get my email and the popups are driving me insane. I am so unbelievably frustrated. I spent a lot of money on a brand new Mac only to have it act like an old PC a few months later. Now I get a new popup that says A kechain cannot be found to store "registrationV1."

Please help.

What OS are your running? If you can access your user library, you can go to Keychains/login.keychain and move it to your desktop. Restart and a new login keychain should be created. If successful, delete the one from your desktop.

A PC won't be any better if your email settings aren't correct. And that includes a lot more settings that just knowing the password for your email account.

Who is your email provider? Don't post your email account name or password, just who you're using; such as Gmail, a local ISP, Yahoo, etc.

Tried that. Moved to trash, reboot. Repaired HD. Reset several times and reboot. Nothing. It just shakes. I have read 4 separate ways to recover keychain password without knowing the old password and all of them = Fail. Only thing I can think is that after doing a complete wipe and re-install / upgrade to El Capitan, I had to create a second user/ admin to find my old passwords hidden in a locked folder. When I did this, that user, became the primary admin. I have since moved myself back to primary but the other user is listed as an admin. Is this causing the keychain to remain locked? How do I erase all other users on macbook pro, OSX 10.8 El.

Thanks.
