# What certificate authority does Batch use for its APIs and Dashboard?

As of February 3, 2026, Batch uses [Let’s Encrypt](https://letsencrypt.org/) as the certificate authority for its API endpoints.

The [dashboard](https://dashboard.batch.com/) will switch to Let's Encrypt on June 1, 2026. 

### What is Let’s Encrypt?

Let’s Encrypt is a modern, automated, and open certificate authority (CA). It issues SSL/TLS certificates to secure HTTPS connections. It’s widely recognized as an industry standard.

### Do you (as a Batch client) need to do anything?

If you use [certificate pinning](https://www.ssl.com/blogs/what-is-certificate-pinning), you must update your trust chain.

Please note that, as part of [modern security best practices](https://www.digicert.com/blog/tls-certificate-lifetimes-will-officially-reduce-to-47-days), certificates are now short-lived by design. Short lifespans require automation. Because of this, we do not support certificate pinning: if you want to harden security, please rely on [Certificate Transparency](https://en.wikipedia.org/wiki/Certificate_Transparency).

Let’s Encrypt’s trust chain is documented [here](https://letsencrypt.org/certificates/). For now, the certificates we emit are valid for 90 days, but this duration might be reduced over time.
