OAuth Token
OAuth Token is an access credential issued through the OAuth 2.0 authorization framework that grants delegated access to resources on behalf of a user.
Why It Matters
OAuth is the industry standard for delegated authorization, used by Google, GitHub, Stripe, and most major platforms. Mismanaged OAuth tokens — stored insecurely, never expired, or over-scoped — are a frequent breach vector.
How It Works
The OAuth 2.0 flow involves: the client requests authorization, the user grants permission, the authorization server issues an access token (and optionally a refresh token), and the client uses the token to access APIs on the user's behalf.
Best Practices
- Request minimal scopes
- Store tokens securely (server-side, not in frontend code)
- Implement token refresh rather than long-lived access tokens
- Revoke tokens when no longer needed
Common Mistakes
- Requesting broad scopes "just in case"
- Never revoking OAuth tokens after use
- Storing refresh tokens in client-side storage
How ShieldKey Helps
ShieldKey can proxy OAuth-authenticated APIs just like API key-authenticated ones. Store the OAuth token in ShieldKey's encrypted vault and issue Shield Tokens to team members.

What is an OAuth token?
An OAuth token is an access credential that lets an application act on behalf of a user. It's issued through the OAuth 2.0 flow and should be scoped to the minimum permissions needed.
