Why won't my iCloud mail account save my password?

Hey there erginc,

It sounds like your computer is not saving your password for your iCloud account in the System Preferences. I found this article and recommend the steps within:

Mail (Mountain Lion): If your password is not saved

http://support.apple.com/kb/PH11775

If you click “Save password” in a dialog in Mail but still have to enter your password, there are a couple of things you can try.

• Open Keychain Access, and then locate and delete the mail account password item. While in Keychain Access, you can also choose Keychain Access > Keychain First Aid to verify and repair keychain settings.
• Open Disk Utility, and then select the volume (for your hard disk or disks) in the list of disks and volumes. Click First Aid and then click Verify Disk. If necessary, click Repair Disk. Then send yourself a test message.

The title mentions Mountain Lion but the steps are relevant to Mavericks as well.

Thank you for using Apple Support Communities.

All the very best,

Sterling

This from another thread:

So I found this and it works:

Open the Mail app. Go to Preferences. Click on the Accounts tab, and then the Advanced tab.

Look for the Authentication box. If you're having this problem, it will be set to "Password." Click on the box and select "Apple Token."

Apple uses Tokens as a secure way to access iCloud services without having to use your password, by providing your username and password to the app over an encrypted SSL connection.
