In order to promote and promote their own products, display the positive image of enterprises, and connect with more business operations, many enterprises have built their own websites, and many enterprises have established more than one website and domain name because of the diversity of their business. In order to increase the credibility of enterprises and make customers more reliable, most enterprises will load SSL certificates in their websites to make the website HTTPS and make the visit more secure and reliable. So, can SSL certificates be used for multiple domain names? Where can I apply for a multi-domain name certificate?

Can the SSL certificate be used by multiple domain names?

Of course, SSL certificates can be used by multiple domain names. According to the number of domain names supported, SSL certificates can be divided into the following three categories:

First: single domain name SSL certificate, that is, only one domain name SSL certificate is supported.

Notes for application:

If you are applying for a SSL certificate for a domain name with a www prefix, the domain name with www and the domain name without www will be protected by default, whereas if you are applying for a SSL certificate for a subdomain name with other prefixes, you can only protect the current subdomain name.

The second kind: multi-domain name SSL certificate, this kind of certificate can support the use of multiple completely different top-level domain names, usually the multi-domain name SSL certificate can support 2200 domain names.

The third type: pan-domain name SSL certificate, this SSL certificate can support all sub-domain names at the same level under the same primary domain name, and there is no limit on the number of sub-domain names at this level.

2. Where to apply for multi-domain name certificate

Applying for a multi-domain name SSL certificate is the same as applying for a general SSL certificate, and you need to apply to a certified digital certificate authority. Of course, it is best to choose a qualified digital certificate authority, so that the applied multi-domain name certificate is more secure and reliable.

At present, there are many digital certificate authorities that can support applying for multi-domain SSL certificates, among which the more famous ones are: Symantec, Comodo, Geotrust and so on. While Aliyun and Tencent Cloud cooperate directly with these digital certificate authorities to provide domestic users with multi-domain name certificate application service, which is worry-free, fast and free of charge for installation guidance, which is suitable for beginners.
