"These include Secure Sockets Layer options, single sign-on capabilities, and administrative controls for how widely users can share and publish information from Google Docs, Google Sites and Google Calendar."
Google has also added a new layer of security with administrator controls that allow enterprises to define the length of passwords and analyse their strength.
The company offered a number of password selection tips. "The first step in protecting your online privacy is creating a safe password, i.e. one that a computer program or persistent individual won't easily be able to guess in a short period of time," the advice reads.
"To help you choose a secure password, we've created a feature that lets you know visually how safe your password is as soon as you create it."
One example, which may seem obvious, is "not to use a password listed as an example of how to pick a good password".
The relative strength of a password can be determined automatically in real time as Google's account authentication system constantly analyses password use and attempts to break them.
