Hi @denis.skorski,

Welcome to the Auth0 Community!

If you pull your connection data from the [GET /api/v2/connections/{id}](https://auth0.com/docs/api/management/v2/connections/get-connections-by-id) endpoint, it should include an expiration for the cert. I just tested it, and it looks like mine is valid for 11 years.

Hope this helps!
