Account logged in on stolen computer

[Capital Gorpo]

Just had a break in where my laptop was lifted. I had steam downloaded and logged in on it and I'm just trying to tie up loose ends.

Basically I had financial info on there and I'd like to see to that being secure - is there any way I can make my account inaccessible from that computer? I already changed my password but I obviously can't test it out.

wait sorry its steam>settings>manage steam guard account security...>deauthorize other devices (or whatever it says :p)

Thanks, I'll try to get on my girlfriend's computer and do that but I can only go from my phone browser or the steam app
