The proposal was made by Ryan Sleevi, Google's representative, at a F2F meeting of the CA/B Forum in Thessaloniki, Greece, in June.
The CA/B Forum is an unofficial industry group made up of certificate authorities (CAs; companies that issue SSL certificates) and browser makers.
Per Sleevi's proposal, starting with March 2020, the lifespan of all newly issued SSL certificates would become 397 days (roughly a year and a month) instead of the current 825 days (about two years and three months).
No vote was held on the proposal; however, most browser vendors expressed their support for the new SSL certificate lifespan.
