1. Field
The present invention relates generally to a technique for eliminating passwords for account access to websites.
2. Background
Many websites require a username and password to authenticate a user and permit user access to the website. A user who seldom uses a website may forget the password for the website. Also, some websites use cookies to store authentication information between sessions, allowing the user to use the website over multiple sessions without reentering the user's password. For frequency visited websites, the authentication information stored in the cookies on the user's computer is relatively fresh, and the user may not need to enter their username and password for a long period of time. Because the user may not need to frequently enter the password, the user may forget the password of an often visited website.
Most websites that require user passwords provide a password reset mechanism that allows the user to receive a new password, typically by means of an email to an address provided by the user when registering for access to the website. Generally, a user may reset their password at any time so, in essence, as long as a user remembers their username, they can forget their password from one session to the next.
However, the forgotten password is still recognized by the website, and an attacker who can figure it out by, for example, guessing or reversing a compromised hash, may access the website. This highlights an undesirable side-effect of the password reset mechanism. The forgotten password is useless to the user, but not to an attacker.
There is therefore a need for a technique for authenticated website access without requiring a password.
An aspect of the present invention may reside in a method for authenticating a device connection for website access without using a website password. In the method, a web server receives an access request over the device connection from a device requesting access to a website based on a pre-established identity. The web server, in response to the access request, forwards an access cookie to the device over the device connection and forwards an activation URL to an address associated with the pre-established identity. The web server receives a request for the forwarded activation URL and, using the access cookie, grants access to the device over the device connection.
In more detailed aspects of the invention, the access cookie may include a session identity. An access state of the device connection may be stored on the web server. The web server may forward the activation URL in an email, or in an SMS message.
In other more detailed aspects of the invention, another device may be used to invoke the activation URL to activate the device connection. The pre-established identity may be a username, or an email address.
Another aspect of the invention may reside in a station for authenticating a device connection for website access without using a website password, comprising: means for receiving an access request over the device connection from a device requesting access to a website based on a pre-established identity; means for forwarding an access cookie to the device over the device connection and forwarding an activation URL to an address associated with the pre-established identity in response to the access request; and means for receiving a request for the forwarded activation URL and, using the access cookie, granting access to the device over the device connection.
Another aspect of the invention may reside in a station for authenticating a device connection for website access without using a website password, comprising: a processor configured to: receive an access request over the device connection from a device requesting access to a website based on a pre-established identity; forward an access cookie to the device over the device connection and forward an activation URL to an address associated with the pre-established identity in response to the access request; and receive a request for the forwarded activation URL and, using the access cookie, grant access to the device over the device connection.
Another aspect of the invention may reside in a computer program product, comprising: computer-readable medium, comprising: code for causing a computer to receive an access request over the device connection from a device requesting access to a website based on a pre-established identity; code for causing a computer to forward an access cookie to the device over the device connection and forward an activation URL to an address associated with the pre-established identity in response to the access request; and code for causing a computer to receive a request for the forwarded activation URL and, using the access cookie, grant access to the device over the device connection.
The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.
With reference to
In more detailed aspects of the invention, the access cookie may include a session identity. An access state of the device connection may be stored on the web server 114. The web server may forward the activation URL in an email, or in an SMS message.
In other more detailed aspects of the invention, another device 102′ may be used to invoke the activation URL to activate the device connection. The pre-established identity may be a username, or an email address.
The present invention may be particularly advantageous when a new device 102 is being used or setup to access a website. Certain features may not be available before setup, such as email, or certain features may not be available on the new device, such as SMS messaging on a tablet or laptop having only WiFi connectivity. As an example, a user may get a new tablet and want to use it to log into an account for a website or web application before setting up a messaging application such as email.
With the present technique, a cookie is immediately forwarded to the requesting device 102, and the activation URL may be accessed by any device 102′, such as a smartphone have cellular data connectivity. Once the other device, e.g., the smartphone, exercises the activation URL, the requesting device is authenticated for a connection session using the forwarded cookie. The website's server 114 would not acknowledge the forwarded cookie until the activation URL is exercised. After activation, the requesting device merely refreshes a web page of the website, and the requesting device is authenticated and logged in without any further action or input needed by the user at the requesting device.
In the present invention, the concept of a connection is made explicit, and allows a user to be active in managing the connections associated with the user's username. The website may maintain a list of active connections in an account profile, and the user may review the list of active connections. Also, a user may create temporary connections to use on a borrowed or loaned device, etc.
With reference to
The website server 304 may send or forward an activation message to a message server 306 (step 340). The message server may be configured to send or forward an email message, an SMS message, or similar out-of-band message, in accordance with the capabilities of a message device 308, e.g., RS 102′ (
With further reference to
Another aspect of the invention may reside in a station (e.g., web server 114 and/or computer 400) for authenticating a device connection for website access without using a website password, comprising: a processor 410 configured to: receive an access request over the device connection from a device 102 requesting access to a website based on a pre-established identity; forward an access cookie to the device over the device connection and forward an activation URL to an address associated with the pre-established identity in response to the access request; and receive a request for the forwarded activation URL and, using the access cookie, grant access to the device over the device connection.
Another aspect of the invention may reside in a computer program product, comprising: computer-readable medium 420, comprising: code for causing a computer 400 to receive an access request over the device connection from a device 102 requesting access to a website based on a pre-established identity; code for causing a computer to forward an access cookie to the device over the device connection and forward an activation URL to an address associated with the pre-established identity in response to the access request; and code for causing a computer to receive a request for the forwarded activation URL and, using the access cookie, grant access to the device over the device connection.
The station 102 may be a remote station RS comprising a computer 400 that includes a processor 410, a storage medium 420 such as memory and/or a disk drive, a display 430, and an input such as a keypad 440, and a wireless connection 450 and/or a wired connection 460 which may include data connection to the internet 110.
