The 47-day certificate countdown

The CA/Browser Forum recently took an official vote to amend the TLS Baseline Requirements, bringing certificate lifespans down to 47 days by 2029 through a series of gradual changes. This comes largely in response to a proposal from Apple, as well as a previous, similar proposal from Google to lower the lifespan to 90 days. The push from major companies is effective at spurring monumental change like this revolutionary policy change. Certificate lifespan is a crucial factor in fighting key compromise incidents, fixing mistaken certificates, ensuring consistency in active domain certificate ownership, and more. The upcoming change is a huge, historic step toward securing the internet and its encryption.
