Let’s Encrypt plans to issue 64-day certificates from February 10, 2027, then move to 45-day lifetimes in 2028. Operators will need to ensure certificate renewal and deployment workflows can handle shorter validity periods.

What

How

- It expects its last 90-day certificate to expire May 11, 2027, then plans to move to 45-day certificates in 2028.
