Decreasing Certificate Lifetimes to 45 Days (letsencrypt.org)

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

Allowing a certificate without proper validation for local only networks is a terrible, terrible idea. I could super easily use this as a loophole to set up a honeypot public free wi-fi, redirect all traffic through a reverse proxy and man-in-the-middle every single HTTPS connection, effectively allowing me to harvest everyone's passwords in a really quick and easy way.

Just use DNS verification. It's not that hard.
