The password are hashed not encrypted (also known as a one-way-
encryption). A hacker getting access to the passwords file cannot
decrypt them. The hacker can "theoretically" find collision but it is
almost impossible with SHA512+HMAC (which web2py uses).

Things are different for the administrator. Nothing prevents the
administrator from intercepting the communications and logging the
password in a separate file. That is true for ANY application, not
just web2py.
