SSL Certificate Validity Periods
How often you need to reissue your SSL certificate
Current Industry Changes
Starting March 15, 2026, Certificate Authorities (CAs) have transitioned to updated SSL issuance regulations. Although the maximum validity period for a secure connection remains one year, a mandatory mechanism for regular domain ownership validation via the reissue procedure has now been implemented.
Key Technical Details
The maintenance of website security has undergone the following adjustments:
- Continuous Oversight: Certificates no longer function indefinitely without periodic verification from the owner.
- Validation Cycles: It is now necessary to systematically undergo re-verification of domain name ownership.
- Rules for Multi-year Plans: Certificates activated for two or more years under previous standards now require mandatory annual updates.
Results of Timely Reissue
The reissue procedure fulfills several critical tasks:
- Guarantees the use of only current and verified owner data.
- Ensures a transition to modern data protection algorithms.
- Prevents security warnings from appearing in browser interfaces.
Important: If the reissue stage is missed, the secure connection may be blocked or flagged as invalid by security systems.
Practical Tips for Stable Operation
To ensure uninterrupted protection for your users, it is recommended to:
- Set reminders for the date of your next scheduled validation.
- Respond promptly to Certificate Authority requests regarding domain confirmation.
- Always update the installed files on your server immediately after the reissue process is complete.
