楼上说的不是安全方面的令牌，而是网络中的令牌。
参考一下wikipedia里面的解释：
A security token may be a physical device that an authorized user of computer services is given to ease authentication.
Security tokens are used to prove one's identity electronically. The token is used in addition to or in place of a password to prove that the customer is who they claim to be. The token acts like an electronic key to access something.Some may store cryptographic keys, such as a digital signature, or biometric data, such as fingerprint minutiae. |
