How does JWT Bearer Token work?

Bearer Tokens are the predominant type of access token used with OAuth 2.0. A Bearer Token is an opaque string, not intended to have any meaning to clients using it . Some servers will issue tokens that are a short string of hexadecimal characters, while others may use structured tokens such as JSON Web Tokens.

In short, JWTs are used as a secure way to authenticate users and share information. Typically, a private key, or secret, is used by the issuer to sign the JWT. The receiver of the JWT will verify the signature to ensure that the token hasn’t been altered after it was signed by the issuer .

To send a GET request with a Bearer Token authorization header, you need to make an HTTP GET request and provide your Bearer Token with the Authorization: Bearer {token} HTTP header .
