Disable Chrome Keychain Access
Prevent or stop Chrome from continually displaying the dialog box "Google Chrome wants to use your confidential information" for keychain access.
You must either click "Always Allow" or delete the passwords entirely from Keychain Access.
Things That Don't Work
Despite being mentioned on other forums, these solutions don't permanently solve the problem:
• Turning off password autofill in Chrome settings
• Reinstalling Chrome
• Running a Terminal command like "defaults write com.google.Keystone.Agent checkInterval 0". Rather, this command alters the frequency with which Google Software Update checks for updates.
