How many instances of the same user can be logged in at once

I have a client that is quite stubborn, and he won’t budge on this. He thinks he needs to keep an area of the site secure, but he knows all his sub-contractors are very tech-challenged. He doesn’t even trust them to register, without having to email/call them a dozen times during the process.

The only way I see this working is to create one web user, which I have done, and they can email out the login details when need be. The Login snippet and everything related is working. I believe he only has a dozen or so sub-contractors, and if I set the "blocked minutes" and "failed attempts" liberally we should be good.

Is there a limit as to how many instances of the same user can be logged in at once? Maybe there is even a better way to do this, as this method is quite ghetto. I have explained all this to the client, but he does like the idea.

Forgot, I am using the latest REVO.

Ok, let’s simplify my question:

Is there a limit as to how many instances of the same user can be logged in at once?

That is a very bad idea. What if one of his subcontractors leaves and you don’t want him to be able to log in any more? Change the password, then notify everybody else and expect them to remember that it’s been changed? If he has his own login you just delete his user. Then there is the matter of locking resources or elements. What happens if two or more users try to edit the same thing at the same time? You’ll have one person’s changes overriding the others, which problem resulted in lock mechanisms for databases and such many years ago.

So while this solution may seem simpler and more secure at first glance, it’s actually trouble waiting to happen.

Susan, it could be useful to only have one account for a group of persons...
For that it would be useful to have a voice about if there’s any restriction? I tested once in Revolution with about 5 people and one login account and it works. But maybe there’s a higher limit?

But generally you need to consider if it’s really the better solution instead of giving every person a separate account.

Thanks for the reply guys. And yes Susan, I am very aware that it is a very bad solution. However, that is still what my client wants. I have fully educated him on all aspects, but he still only wants one login.

With that being said, I am still wondering what the limits are w/ the system.
