Factorio Forums

You can use the same account to play with multiple people. This is done by:

- reinstall/install the game
- on the login screen that comes up, you type your user name but change some of the capitalisation. i.e. (gathorisx, GatThorisX etc..)
- enter the password and it will work
- when you join a server, instead of your usual name, you have your name in weird caps and the same account can be used by multiple people to play together.

I discovered this bug when i was trying to find out if i could play with friends on the same account. we had fun but they still didn't buy it so we kept using it. It should probably be fixed so that they are forced to buy it

Do you have "require authentication" enabled? If not, anyone can join regardless of actually owning the game.

yes.

I think the problem is: authentication doesn't check capitalization.

I just typed "MOONcat" and it still logged me in.
But I haven't checked if I can play with my another instance.

Yes, authentication is case insensitive, which is correct.

I fixed, that factorio checks users lower cased when:

• Checking whether the user is already in the game
• Checking whether the user isn't banned
• Checking whether the user should be admin

Thanks, but why not make it to be case sensitive? Just curious.

Case sensitive is only really useful when it comes to login usernames and passwords. Display usernames being case sensitive (as in allowing 2 different users to have the same spelling but different case) would be extremely confusing to everyone involved.

Making it possible to create and use accounts Kovarex kOvarex, koVarex and considering them to be completely separate users seems just wrong.
When I'm thinking about it, shouldn't we also unify O and 0? (The letter O versus the number 0).
KOVAREX and K0VAREX looks very similar as well.

Same goes for I, l and 1!

I think that's going a bit too far. Someone would have to register an additional account (buy an extra copy) to screw with people that way. Your example also isn't helpful as most of the time the letter O is used as lowercase o.
That said, if you were to implement that you should also consider I (uppercase i) and l (lowercase L). In Factorio's font they pretty much look the same.

Oh, I see we are concerning about 2 different problems.

I asked that because the OP was talking about sharing account to the people who haven't bought the game, hence I was thinking about allowing only one instance of the same account to be logged in at the same time. In that case, it should be case-sensitive.
But now I realized we don't have such thing. So, yes, case-INsensitive should be better for now. Thanks for the answers.

About O vs 0 and I vs l (very good example!), I haven't seen any game that unify them, including MMORPGs. I think it is a bit overkill. If someone is going to pretend to be anybody, there are many ways to do so. He can say "my account got hacked, so I create a new one". Some people will believe him. lol
