## tlsclient

The tlsclient profile is _currently_ identical to the classic profile. However,
as [announced on our blog](/2025/05/14/ending-tls-client-authentication):
Certificates issued with the tlsclient profile contain the TLS Client Auth EKU.
It is otherwise identical to the classic profile.

- on February 11, 2026, the TLS Client Auth EKU will be removed from the classic
profile, but will remain in this profile; and
- on May 13, 2026, this profile will cease to exist.
However, as [announced on our blog](/2025/05/14/ending-tls-client-authentication),
this profile will cease to exist on May 13, 2026.

This profile exists for the sole purpose of allowing Subscribers who need access
to TLS Client Auth certificates to retain that EKU for slightly longer, to
ease their transition into a TLS Server Auth-only world. If you do not
specifically need the TLS Client Auth EKU, or if you do need it but are able to
migrate away from it before February 2026, then you can and should safely ignore

## Removal of TLS Client Authentication EKU

On February 11, 2026, we intend to [remove the "TLS Client Authentication" Extended Key Usage (EKU)](https://letsencrypt.org/2025/05/14/ending-tls-client-authentication/) from our default certificate profile. Prior to that date, we will offer an alternative profile which will still contain that EKU, but note that this will be a temporary stop-gap for clients that need more time to migrate away from needing it: that alternate profile will go away on May 13, 2026.
