What is a Bearer Token?

Definition

Any party in possession of a bearer token (a “bearer”) can use it to get access to the associated resources (without demonstrating possession of a cryptographic key). To prevent misuse, bearer tokens need to be protected from disclosure in storage and in transport.

Tyk provides bearer token access as one of the most convenient building blocks for managing security to your API, in a Tyk setup, this is called “Access Tokens” and is the default mode of any API Definition created for Tyk.

Bearer tokens are added to a request as a header or as a query parameter, if added as a header, they may be preceded by the word “Bearer” to indicate their type, though this is optional.

Traditionally these tokens are used as part of the Authorization header.
