Remember-Me-cookie - where to store token

Question

I'm currently implenting the user-authentication on my website and for convenience, I want to implement a remember me feature. The website is a free game, security is not of the utmost priority since no personal date is stored - apart from e-mail address and password (using PHPass framework).

Now where to store the token for the cookie? When I read around the web, most sites seem to want to place it in a seperate table, but never mention why.

So I'm thinking of storing it in my 'users'-table, where (hashed) password, e-mail address and some other info is stored. I'd add a column "token" and if the users logs in with "remember me" flagged, I'll create a token and store it there.

Is that somehow not good practice?

Answer 1

Separated table is better because user could authenticate from several browsers/machines, thus you need to be able to track several tokens per user.

So create additional table for that
