Secret Manager v1 API is deprecated
The Secret Manager v1 API will be removed on 2026-09-30. Migrate to v2 before then to avoid disruption.
What’s different in v2
- Versioned secrets with rollback
- Per-field encryption metadata
- KMS-backed encryption keys (BYOK supported)
- Faster reads (~3× lower p99 latency)
Migration
The migration is idempotent and rollback-safe. Audit logs record each migrated secret.
