Managing multiple api callback authentications without juggling credentials?

Our system integrates with 7 different platforms needing unique OAuth2/OAuth1 flows for callbacks. Maintaining refresh tokens and API keys across all services is becoming a security nightmare.

Is there a unified solution that handles token rotation and SSO for third-party API callbacks? Preferably without storing credentials ourselves.

Latenode handles this through their platform auth system. We connected 12 services once and it manages token refreshes/SSO automatically. Creds stay encrypted on their side.

Consider Vault by HashiCorp for credential management. We implemented it with a custom OAuth2 proxy that handles token rotations. Integrates with major cloud providers but requires significant infrastructure investment. Not ideal for small teams.
