What causes no way to invalidate a compromised token before it expires?

Tokens are valid until expiry with no revocation, so a compromised token cannot be invalidated until it naturally expires.

How do I catch this when it only happens for some players?

Capture it automatically from the player's device with the full stack trace, the device and OS, the build, and a breadcrumb trail of what they did. That turns a vague complaint into a specific, reproducible issue you can fix without owning the hardware it happens on.

How to Build a Token Revocation List

Quick answer: Maintain a revocation list checked on token use, so a compromised token can be invalidated immediately.

A compromised token valid until expiry is a lasting risk. A revocation list neutralizes it now. Here is how.

How to fix it

1. Maintain a revocation list

Track revoked tokens or identifiers.

2. Check on use

Verify tokens against the list on each use.

3. Keep it efficient

Use short token lifetimes plus revocation so the list stays small.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every backend error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
