Please change need to enter master password every two weeks.

EnerJi it should be an option turned on by default, not a requirement. I don't feel this is secure at all. Re-entering master password so frequent increases the chance of exposing your password.

rzzz You must have unusual requirements if entering your master password every two weeks significantly increases your chance of exposing your password. My hunch is that people forgetting their master password is a much bigger risk.
