Those unprotected Jwt should contain a `alg` header with value `"none"`, but you can change that value
by passing an `alg` parameter if you know what you are doing.

Args:
claims: the claims to set in the token.
alg: the `alg` value to set as header.
typ: typ (token type) header to include. If `None`, do not include this header.
extra_headers: additional headers to insert in the token.
