Is it possible to make a website with only one account per person?
Any suggestion is good.
Thanks

If you don't want people to go generating 100 accounts a minute, you'll need something like captcha, which is very easy to add on to your website.
You can do other things, like associate each account with an email address, and make the user verify that that email actually exists by sending a link out to that email address so that when they click on it, it verifies the connection.
To associate exactly one account per person, you are going to need to use some sort of official identity, and usually for smaller websites that doesn't make sense. By official identity I mean verify their credit card or government identification (social security?), but then you run into a lot of problems because people won't want to do this, and it is going to cost money to make sure that these identities are real. Also, if you really need something like this, you're going to have to beef up the security of your website.

An alternative is to require a user to put in a verification number which you send to them via SMS, and ensure the phone number they enter is unique, phones/simcards are relatively cheap these days, but most people wouldn't go through the effort of spending $5 on a new simcard to get a duplicate account on your site.
(and if they would, sell accounts for $3 and undercut the cost of a sim ;)

Ask for identifying information for example credit card data that you can verify and allow registrations only with this identifying information. Of course credit card data can be stolen, so you cannot be 100% sure about anything in internet or in world generally.

Whatever you do, people will still try to buck the system. If you use Email, then people can have multiple free emails, if you block free emails, lots of people dont have any other emails so you block them. If you use IP you block anyone with a shared IP such as ISPs who enforce proxy servers for their clients.
Unless you start asking for social security numbers or NI or whatever your country has, and you start alienating people as a rule because they would consider that irrelevant personal information.
You just have to hope people treat your site fairly, and know some wont.

One potential solution these days is to only create user accounts via federation of identity from a much stricter service provider. For example, verify your users via a facebook account using oauth. I believe facebook is pretty good at detecting shills/spammers and you can harness their resources in your service too.

I think you have 2 options, neither of which will solve the whole problem:
Log the IP address and prevent multiple logins from one IP. Not great, as this will probably backfire if college kids use your site and the dorm uses shared IPs.
Log the MAC address and prevent multiple logins from one MAC. Better, but it will prevent multiple people from the same household from using your site, and most houses have more than one computer/mobile device.
You could always combine the two options, but again with multiple mobile devices it's possible to circumnavigate that.

you could make a code that only lets 1 account be made per computer used. you have to be able to get the computers IP address and block it from making more than 1 account.
