what is the lifespan of an access token in the FB oAuth API?
Not the extended offline permissioning, just a normal access token?

A:
If you don't specify the offline permission, then the token is only valid while the user is signed in to Facebook and only until the expiry that gets passed back to you passes. I think it is somewhere around 2 hours generally but I haven't verified it. You can find more information from Facebook's documentation.
