Duress code

I'm looking into the possibilities of adding a Duress code (https://en.wikipedia.org/wiki/Duress_code) to our platform. Is there a way to set this up in Dolphin?

For example your password + 4 digits, when entered in the login form your profile gets deactivated,  so messages, info etc. isn't accessible. 

Or a custom field on profile edit, where members can add a duress code / password. If they enter that code in login, the profile gets deactivated for that moment. 

Unless their account has been hacked; a member can suspend their account at any time through the account page.

Yes, but it would be better on login. Members must login on every visit at our platform. That way it's safer...

Also the profile must be deactivated / suspended till we contact you and activate it back again. This for security reasons.

What you want can be done but it probably won't be answered in the forums; it requires some serious code changes or the creation of a module and since it is so specific I doubt you will see a mod in the market for it any time soon.  You could put in a job for this; http://boonex.com/jobs/

Ok, thanks for the tip! However if this would be a module, it would be a nice tool for some sites.
Do you know if it's allowed to get it build by someone and then sell this as Module in the Market? With the approval of the developer off course ;) I mean can everybody sell modules in the market of do I need to buy first a special licence for that ?
