[TYPO3-english] one input field login

[Katja Lampela]

Hi,

My client wants to give his customers one code with which the customer 
can login to personalized (by the code) content.

Now having username and password is too much for this client. He wants 
there to be only one input form.

There are many normal fegroups and feusers in this same site, so we 
can't customize it too much.

Any ideas how to achieve this one-input-field-login or would it even be 
possible?
