First Flight #1: PasswordStore

The developer of the contract failed to restrict access to the functions getPassword(LN26) and setPassword(LN35), allowing those functions to be called by anyone.
If the password is used a requirement to access resources from the protocol, those recourses would be available to anyone who calls the getPassword function.
If the password is also used as a requirement to change the protocols settings, or to change the protocols state, someone with malicious intent could change the password and hence, set the protocol to a state where it fails to function as it should.

Mitigation Advice:
set A modifier called only owner that checks if the msg.sender == owner, and reverts if not.
This modifier should be applied to the setPassword and getPassword functions.
