Teddy ID is a secure authentication service that allows your users to log in to your site by tapping just one button on user’s phone, without entering a password, yet as secure as modern internet banking sites. Every time a user logs in to your site, TeddyID recognizes the user automatically and sends a picture to his phone and to his computer. The user makes sure the pictures match and approves login by tapping “Yes” button in TeddyID app on his phone. Passwords are no longer needed, and security is ensured by use of two devices associated with the user: a computer and a phone. This is two factor authentication made simple.
