Security Token Question

[WhiteGarden]

My security token is getting older - I'm wondering if it dies what information I need to get back into my account. I'm sort of scared that it will die and SE will give me trouble about getting back in (I assume I would have to call them). I thought it would be good to keep a record of whatever info I would need.

Any ideas? I've read about some one-time emergency-removal password you can set in your account but I don't see that option in mine. I have the hardware token, not the software one.

Thanks!
