Industry Shift to 47-Day SSL/TLS Certificate Validity by 2029

Beginning in March 2026, SSL/TLS certificates will gradually move from the current 398-day validity period to a significantly shorter 47-day lifespan by 2029. On April 11, 2025, the CA/Browser Forum approved Ballot SC-081v3, a proposal from Apple that aims to reshape how organisations manage certificates and validation lifespans. The ballot reduces certificate lifetimes to:

March 2026: Approximately 6-month validity, March 2027: Approximately 3-month validity, March 2029: 47-day validity
