The rise in interest around two-factor authentication among embattled online service providers may look like the solution to securing end-user logins, but it is only one piece of a long-term project, according to a pair of security experts.
Just last week, Evernote became the latest service provider to commit to offering a two-factor authentication option to its end-users. A hack of the company's systems forced it to reset 50 million passwords.
Already, Facebook, Google
, Amazon, Microsoft, PayPal, and Yahoo
are committed to two-factor authentication options for end-users.
Twitter, which was hacked last month and lost 250,000 passwords, is under pressure to join the group
and offer two-factor authentication, which is the addition to the common password of a second piece of identification in order to gain access to computer resources.
