RSA Security Token

What is a RSA Security Token? How can I start using the RSA Security Token on my account? Is there a way to disable this feature once I have activated it on my account? What happens if I lose my RSA Security Token? I don’t have my RSA Security Token, and I don’t have my One Time Passwords handy, but I’ve got a tournament starting soon and need to access my account in a hurry. What do I do? I’ve forgotten my RSA Security PIN. How do I recover it? How do I obtain more One Time Passwords? Will using a RSA Security Token make my account completely secure? Can I share my RSA Security Token with a friend? How long will the RSA Security Token operate for?
