Tokens can contain chips with functions varying from very simple to very complex, including multiple authentication methods. The simplest security tokens do not need any connection to a computer. The tokens have a physical display; the authenticating user simply enters the displayed number to log in.
When software implementations of the same algorithm ("software tokens") appeared on the market, public code had been developed by the security community allowing a user to emulate RSA SecurID in software, but only if they have access to a current RSA SecurID code, and the original 64-bit RSA SecurID seed file introduced to the server.

An access token is an object encapsulating the security identity of a process or thread. [1] A token is used to make security decisions and to store tamper-proof information about some system entity. While a token is generally used to represent only security information, it is capable of holding additional free-form data that can be attached ...
Tokenization, when applied to data security, is the process of substituting a sensitive data element with a non-sensitive equivalent, referred to as a token, that has no intrinsic or exploitable meaning or value. The token is a reference (i.e. identifier) that maps back to the sensitive data through a tokenization system.
RSA SecurID security tokens. RSA Security's SecurID is one example of a time-synchronization type of token, along with HID Global's solutions. Like all tokens, these may be lost, damaged, or stolen; additionally, there is an inconvenience as batteries die, especially for tokens without a recharging facility or with a non-replaceable battery.
If you no longer have your Security Key, use these steps: Go to the Sign-In Helper. Sign in and go to the AOL Account Security page. Turn off Security Key 2-Step Verification. When you get your Security Key back or get a new key, you can re-enable 2-Step Verification in your Account Security settings.
The security of the RSA cryptosystem is based on two mathematical problems: the problem of factoring large numbers and the RSA problem. Full decryption of an RSA ciphertext is thought to be infeasible on the assumption that both of these problems are hard , i.e., no efficient algorithm exists for solving them.
