Mail (Mountain Lion): If Mail keeps asking for your keychain password
If Mail keeps asking for your keychain password, your keychain may be set to lock after a certain amount of time or when your Mac goes to sleep.
You can change the keychain lock settings to reduce the number of requests for your keychain password.
- Open Keychain Access.
- In the sidebar, click All Items in the Category section, and then select your login keychain.
- Choose Edit > “Change Settings for Keychain ‘login’.”
To reduce the number of requests for your keychain password, deselect the “Lock after [number] minutes of inactivity” checkbox, or increase the number of minutes. You can also deselect the “Lock when sleeping” checkbox.
