Any other method to overcome these limitations of the above suggested method.

***Limitations***

This method of authentication has certain limitations.

* Only the user password is secured. All other communication is sent in the clear. For example the username is sent in clear-text, which exposes the user's activity.
* Client may not support JavaScript, which is required to compute the MD5 response. ///Support for such clients may be added through the plain-text login.
* This mechanism only protects against passive eavesdropping. If an attacker was able to act as a proxy between the client and the server, it would be possible to substitute the login JavaScript mechanism with one that sent the password in clear. The attacker would then compute the response using the user's password and authenticate with the server.

Despite these limitations, the MD5 challenge-response method of authentication is in use by some of the most popular sites on the internet including Yahoo!, which is a testament of its credibility.
