# Supabase: rotate the JWT signing key — Project Settings → JWT Keys → JWT Signing Keys → Rotate Keys → Revoke old key

## Steps
1. Go to **Project Settings** > **JWT Keys** in the Supabase Dashboard.
2. Open the **JWT Signing Keys** tab.
3. Click **Rotate Keys**. This moves the current key to "Previously used keys."
4. On the previously-used key's row, select the three-dot action icon and click **Revoke**.

## End state
A new signing key becomes active; if the old key isn't explicitly revoked, it keeps validating tokens signed with it. This flow is for projects already migrated to asymmetric/new JWT signing keys.

Moved from: on the legacy (pre-migration) JWT secret, Supabase says it is "no longer possible to rotate the legacy anon, service and JWT secrets" — that path requires migrating to signing keys first.
