TLS Certificates Get Shorter Shelves Lives: Brace for a 47-Day Expiration by 2029!
TLS certificates are getting a makeover! Major internet companies have agreed to shorten their lifespan to 47 days by 2029. While this promises better security, it also means more frequent renewals. But don’t worry, automation is here to save the day, so you won’t be tied to your desk renewing certificates manually!

Hot Take:
Brace yourselves, folks! The future of internet security is going to be a whirlwind of 47-day TLS certificates! It’s like speed dating for the digital realm—short, sweet, and demanding your undivided attention every other month. Who knew that keeping the internet secure would turn into a part-time job? Time to polish those automation skills, because manual renewal is going the way of dial-up internet and floppy disks.
Key Points:
- Major internet companies aim to reduce TLS certificate lifespan to 47 days by 2029.
- The current 398-day validity will decrease to 200 days in 2026, 100 days in 2027, and eventually 47 days in 2029.
- Companies backing this schedule include Google, Apple, Mozilla, Microsoft, and more.
- Shorter certificate lifespans enhance security but pose challenges for organizations with manual renewal processes.
- Automation of certificate management is expected to increase with these changes.
