CCSP Cloud Application Security Practice Question
A cloud application uses OAuth 2.0 for authorization. What is the primary purpose of using a refresh token in this flow?
⚠ Common exam trap
ISC2 often tests the misconception that refresh tokens are used for authentication or that they extend the life of the same access token, rather than understanding they are a separate credential used to obtain a new access token.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
To obtain a new access token when the current one expires without user interaction.
In OAuth 2.0, access tokens are short-lived by design to limit the window of compromise. A refresh token is a long-lived credential that allows the client to obtain a new access token from the authorization server without requiring the user to re-authenticate or re-consent. This enables seamless, ongoing access to protected resources while maintaining security through short-lived access tokens.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
To obtain a new access token when the current one expires without user interaction.
Why this is correct
Refresh tokens are long-lived and can be used to request new access tokens.
- ✗
To grant the same access token indefinitely.
Why it's wrong here
Access tokens expire; refresh tokens allow renewal, but they can be revoked.
- ✗
To authenticate the user without a password.
Why it's wrong here
Refresh tokens are for authorization, not authentication.
- ✗
To store user credentials on the resource server for later use.
Why it's wrong here
Refresh tokens are stored on the client, not the resource server.
