TLS certificate lifetimes will officially reduce to 47 days, with gradual reductions leading up to this date. Starting March 15, 2026, the maximum lifetime will be 200 days, decreasing to 100 days in 2027, and finally reaching 47 days by March 15, 2029. This change aims to enhance trust in certificate information and improve revocation reliability. Automation will be essential for managing these shorter lifetimes. Despite concerns about increased costs from more frequent replacements, it is anticipated that automation will mitigate this issue.
