Notice: I would like this a lot right now.
I would like a new column in the database where a product key can be stored for 3rd party ideas. I have an additional column in my database right now which I can't see on my forum anywhere because I would need to make my own mod to show the value.
Basically a new column named: product_key (in smf_members)
Forum profile field which displays the MySQL field's data to only the user & admin can set/change the value accordingly.
This would help a number of software developers to make secure product keys to there application etc.
I currently produce a new key and store it in a hidden column at the moment and it annoys me that I can't see it on my forum unless I mod it.
I may have a go myself but I probably would do something that wasn't secure enough as I have had problems making a secure login.php for a program I am developing.
An API system for login would be a nice thing but security is paramount.
It would do something like this mod does but be there by default:
use the feature of 2.0 called custom profile fields....
it can be set to be entered by the user but seen only by the user and admins.
no need for a mod at all.
