The maximum validity period of an SSL certificate is 13 months. Is it necessary to apply for multiple years at a time?

Because Apple, Microsoft, Firefox, Google and other browser or operating system developers have indicated that they no longer trust TLS/SSL certificates issued on or after September 1, 2020 with a validity period of more than 398 days, all September 1, 2020New TLS/SSL certificates issued after this date will only have a maximum validity period of 13 months (397 days to be exact).Since the implementation of this rule for more than two years, many users have adapted to the operation of renewing the certificate once a year.This method sacrifices certain convenience, but improves the security and credibility of the SSL certificate.

But when the customer inquires, if it is determined that the current website is a long-term project and an SSL certificate is required every year, it is recommended that the user apply for a multi-year order at one time, mainly for the following reasons:

1. Before the SSL certificate is issued, there is an authentication link, and it is not necessary to pay for the certificate at any time.At present, many certificates need to be verified again when renewing, so it will increase the workload of customers to cooperate with verification.And if you purchased a two-year certificate, you can extract the certificate for the next year one month before the expiration of the first year. Most certificates can directly issue the second-year SSL certificate without verification.

2. Eliminate the business process of annual procurement.If you apply for a one-year certificate, you need to do the SSL certificate procurement process again before it expires, especially for those units whose procurement process is cumbersome and complicated. Sometimes the SSL certificate has expired, and the procurement process may not be completed.

3. One-time purchase of SSL certificates for many years, the CA agency will give more discounts.This can reduce the cost of using the SSL certificate with the validity period.
