Let's Encrypt will reduce the default validity period for its TLS certificates from 90 days to 64 days starting February 10, 2027, unless administrators already opt for shorter 45- or six-day certificates. Existing certificates remain valid until expiration, with the last 90-day certificate expected to expire by May 11, 2027, and no certificates will be revoked during the transition. The organization plans a further cut to 45 days by 2028, and will shrink domain authorization reuse windows from 30 days to 10 days in 2027, and eventually to seven hours by 2028.
