JWKS rotation frequency

Questions
1

Hi,

From Okta doc, the JWKS keys rotation is 4 times a year except emergency rotation. If my app fetches every 5 mintues, it would seem to be pretty plenty? should I reduce the frequency? For new apps, can I start without caching of the keys and add it later if there is a slowdown?

Thank you.

Hi @libra04ts,

Every 5 minutes is quite frequent. Best practice is to

  1. cache the key and update it periodically, say once a day (or even less frequently).
  2. Use the nextRotation data to preempt when to update the cache.
  3. Having logic fetch new the JWKs to handle when JWT validation fails due to an expired or rotated key.
