Keychain Passwords and Safari
The Keychain program on Macs can be a lot of trouble, both serious and annoying. The serious part is that once you have logged onto your account, anyone can open anything. Not a good idea in an era of easily stolen laptops.
The annoying part is when you change your password, the Keychain doesn’t update everywhere, especially in Safari.

I suggest stopping at step 6 as I don’t recommend creating a new keychain.
This does a fairly good job of resetting the keychain—except for Safari. After you have deleted the keychain and the file, open Safari and reset it.
This should stop Safari from continuing to prompt for a keychain password.
