The RSA SecurID authentication mechanism consists of a "token"—either hardware (e.g. a key fob) or software (a soft token)—which is assigned to a computer user and which creates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card's factory-encoded almost random key (known as the "seed").
RSA is most known for its SecurID product, which provides two-factor authentication to hundreds of technologies utilizing hardware tokens that rotate keys on timed intervals, software tokens, and one-time codes. In 2016, RSA re-branded the SecurID platform as RSA SecurID Access. [58] This release added Single-Sign-On capabilities and cloud ...
The security of RSA relies on the practical difficulty of factoring the product of two large prime numbers, the "factoring problem". Breaking RSA encryption is known as the RSA problem. Whether it is as difficult as the factoring problem is an open question. [3] There are no published methods to defeat the system if a large enough key is used.
However, some such systems, such as RSA's SecurID, allow the user to re-synchronize the server with the token, sometimes by entering several consecutive passcodes. Most also cannot have replaceable batteries and only last up to 5 years before having to be replaced – so there is an additional cost. [ 3 ]
RSA SecurID token, an example of a disconnected token generator Possession factors ("something only the user has") have been used for authentication for centuries, in the form of a key to a lock. The basic principle is that the key embodies a secret that is shared between the lock and the key, and the same principle underlies possession factor ...
The most popular type of security token (RSA SecurID) displays a number which changes every minute. Users are authenticated by entering a personal identification number and the number on the token. The token contains a time of day clock and a unique seed value, and the number displayed is a cryptographic hash of the seed value and the time of day.

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.
