TL;DR: JWTs describe token format while bearer tokens describe how credentials are transmitted, and the two are often combined in OAuth 2.0 and OpenID Connect flows, according to Descope. The distinction matters because possession of a bearer token grants access, so revocation, storage, and validation choices shape security outcomes far more than syntax does.
Editorial analysis by NHI Mgmt Group, based on content published by Descope: “JWT vs. Bearer Token: What’s the Difference?”.
Key questions
Q: How should security teams choose between JWTs and opaque tokens for APIs?
A: Choose JWTs when distributed validation, low latency, and stateless scale matter most.
Q: What happens when a bearer token is stolen or intercepted?
A: Whoever holds the token can usually act as the authorised user or service until the token expires or is revoked.
Q: How do identity teams know JWT claims are being trusted safely?
A: They should verify that the token signature, issuer, audience, and expiration checks are enforced on every request path that accepts the token.
Practitioner guidance
- Define the token layer explicitly Document whether each API uses JWTs, opaque tokens, or both, and record whether the bearer scheme, not the token format, is carrying authorisation risk.
- Shorten bearer token lifetime Set expiration tightly enough that a stolen token has a limited replay window, and align refresh behaviour with the sensitivity of the protected API.
- Protect client-side token storage Keep bearer tokens out of insecure browser and application storage paths, and prefer storage patterns that reduce exposure to script access and accidental logging.
Bottom line: Bearer tokens create risk because possession alone is sufficient for access, so token handling must be governed like credential management.

Token syntax is not the governance problem: JWT versus bearer token confusion persists because teams focus on format while the actual risk sits in transport, storage, revocation, and claim lifetime. A bearer token can be opaque or self-contained, and a JWT can be used inside that scheme. The practitioner mistake is treating string format as the security control instead of the identity lifecycle around the token.
A few things that frame the scale:
- Only 44% of developers are reported to follow security best practices for secrets management, exposing a significant developer behaviour gap, according to the State of Secrets in AppSec.
A question worth separating out:
Q: What is the difference between JWTs and bearer tokens in OAuth and OIDC?
A: In OAuth and OIDC, bearer describes how the credential is presented and JWT describes the token's internal structure. A JWT can be used as a bearer token, but it does not have to be. The distinction matters because transport security, revocation, and client storage are separate governance decisions.
