Day 17: Token Vault: Safer by Design

Challenge Task: Explain how Token Vault keeps long‑lived provider tokens out of your app and what your app handles instead.

Post to complete: A tiny sequence + 2 bullets on “why safer”.

When a user signs in with a third-party connection such as Google, Microsoft, Slack, or GitHub, the resulting access and refresh tokens are placed into a “token vault”, which is a secure storage, powered by your Auth0 SDK of choice. Your application or agent never touches those provider refresh tokens directly. Instead, it only holds an Auth0 access token and/or refresh token, which is handled by our SDKs.

  • Long-lived refresh tokens never live on your servers or in environment variables; if your app is compromised, attackers only find short-lived tokens that likely already expired.
  • The vault automatically handles complex refresh logic and maintains a full audit trail of exactly which service requested what token and when.
