Apple proposes to shorten the validity period of SSL Certificates to 45 days starting from April 15, 2027
Shortening the validity period of SSL Certificates to 45 days is an industry trend. This trend is mainly driven by Apple, which proposes to gradually shorten the validity period of SSL Certificates, eventually reducing it to 45 days in 2027.
The specific plan is as follows:
From September 15, 2025 to September 14, 2026, the certificate validity period will be shortened to 200 days
From September 15, 2026 to April 14, 2027, the certificate validity period will be shortened to 100 days
Starting from April 15, 2027, the certificate validity period will be shortened to 45 days
Driving factors and background information
The shortening of the validity period of SSL Certificates is mainly to improve Internet security. In the past, the validity period of SSL Certificates was as long as eight years, but in recent years, in order to cope with the increasingly complex network environment, the validity period has been gradually shortened. For example, the maximum validity period for certificates has been shortened to 13 months in 2020, while Google proposed shortening the validity period from 398 days to 90 days in 2020. Apple's proposal further shortens the validity period, ultimately setting it at 45 days
Industry reactions and potential impacts
This change has caused widespread discussion and controversy. Many webmasters and system administrators are concerned that more frequent certificate updates will increase workload, especially for websites that have not yet implemented automated updates, which will pose additional challenges. However, there are also views that shorter certificate validity periods can reduce the risk of online criminals using expired certificates to attack, thereby improving network security
Specific implementation time and execution details
Apple's proposal is on the discussion agenda, and although it is still under discussion, many industry practitioners believe the change will eventually be implemented. This means that starting from 2027, the validity period of SSL Certificates for all websites will be shortened to 45 days.
