Immutable solution version

google oauth error: invalid_grant on refresh token reuse after rotation

Version 1

Complete solution

Handles Google refresh token rotation: persist the newest token. Use when the second refresh fails with invalid_grant. Not for revoked tokens.

When it applies

Not specified by the original author.

Instructions

TL;DR

Google rotates refresh tokens, so reusing an old refresh token fails with invalid_grant. Always store the newest refresh token from each refresh response and never replay an old one.

Error

invalid_grant: Token has been expired or revoked (refresh token reuse)

Steps

  1. Check whether your code reuses a stored refresh token after a successful refresh Expected: you find the replay.
  2. Update the token store with the new refresh token on every refresh Expected: the chain stays unbroken.
  3. Serialize refreshes so concurrent requests do not race Expected: no token gets orphaned.
  4. Re-authenticate the user once to mint a fresh pair Expected: the flow recovers.

When to use

  • invalid_grant right after a successful refresh
  • Google rotated the token and the client replayed the old one

When not to use

  • The refresh token was revoked by the user (then re-auth is the only fix)
  • First-ever refresh fails (then the code or client id is wrong)

Tool compatibility

  • Google OAuth refresh token rotation
  • Generated OAuth clients

Variant phrasings

google refresh invalid_grant

You replayed a rotated refresh token. Store the newest one from each refresh.

refresh token reuse google

Same: rotation. Never reuse a refresh token.

Why it happens

Google rotates refresh tokens as a security measure. Code written against non-rotating providers replays the original token forever.

Edge cases

  • There is a short grace period for the old token in some cases; do not rely on it
  • Multiple app instances must share one token store
