Speed up the configuration of your SSL certificate by letting ZeroSSL auto-generate your Certificate Signing Request instead of entering general, admin and tech contact information manually, or simply paste your existing CSR.
One-Step email validation is the fastest way of verifying one or multiple domain for your SSL certificate. Select one of the available email aliases (example: [email protected]) and click the confirmation link sent to that email inbox.
If validating your domain name via email is not an option, another quick alternative is DNS validation. ZeroSSL will generate a CNAME value for you to add as a DNS entry.
To validate one or multiple domains in your SSL certificate you can also choose HTTP file upload and place an auto-generated, lightweight text file to your server.
