47-Day Certificates
Public TLS certificates shrink from 398 days to 47 days, so every website renews far more often.

What’s changing, and when
The CA/Browser Forum approved Ballot SC081v3 in April 2025, cutting the maximum life of publicly trusted TLS certificates in steps. Certificates issued from 15 March 2026 may last at most 200 days, from 15 March 2027 at most 100 days, and from 15 March 2029 at most 47 days. Domain validation data can be reused for only 10 days by the end of the schedule.
- Mar 2026 Maximum certificate life 200 days
- Mar 2027 Maximum certificate life 100 days
- Mar 2029 Maximum certificate life 47 days
Why it can’t happen in one step
Every certificate, server and device that still renews by hand has to be found and automated first, and each step arrives whether that work is done or not.
How Polymonial carries you across
- Keys and certificates change often without breaking the identity customers trust.
- Old and new certificates stay trusted side by side through each changeover.
Trust that travels.
Secure, trusted and under your control.
