This week I finally shipped the OAuth2 PKCE migration to the auth service after weeks of design and testing. The change adds a cryptographically‑secure code challenge to every authorization request, closing a long‑standing security gap.
The rollout involved updating the token endpoint, adding nonce validation, and writing extensive unit tests. I hit a few surprising edge cases with token nonces, which taught me the importance of strict entropy checks and led to a small refactor of the crypto helper library.
Looking ahead, the next step is to roll out the changes to the client libraries and monitor adoption metrics. Early internal tests show a 15% drop in token‑related errors, which is encouraging.

PKCE token nonce validation
I dug into the nonce validation logic and discovered that an off‑by‑one error could cause intermittent token rejections. Fixing it required a careful review of the cryptographic random generator usage and added a fallback for low‑entropy environments.
