To add additional proofs, such as a trusted PC or cell phone, to a Hotmail account, users must click "Options" in the upper right of the Hotmail screen, select "More options..." from the drop-down menu, then click "View and edit personal information" under the subheading of "Mange your account." The proofs can be added under "Password reset information."
Microsoft isn't the only Web mail provider beefing up security. Last week, Google announced two-factor authorization that lets businesses protect Gmail log-ins by delivering a one-time code to a cell phone via text message.
Hotmail has had a similar feature, dubbed "single-use codes," for several months.
"We're making the proofs for users more secure so hackers can't lock them out," said Lewis.
