Two-Factor Authentication

Nowadays, many organizations support remote access to the servers that consist of confidential corporate data. Using passwords to verify a person using the remote access might have been a good idea ten years back, not anymore. That's because when it comes to protecting high-stake information, passwords are simply not good enough, you need more than that. You need to take a step further to make sure that the person trying to log in is an authorized person, not someone who has stolen username and password.

Comodo Personal Authentication Certificate eliminates this weak link by verifying a person twice through two-factor authentication.
