Decreasing Certificate Lifetimes to 45 Days - Let's Encrypt

"These challenges are why we are working with our partners at the CA/Browser Forum and IETF to standardize a new validation method called DNS-PERSIST-01. The key advantage of this new method is that the DNS TXT entry used to demonstrate control does not have to change every renewal."

Nice! 😍
