Decreasing Certificate Lifetimes to 45 Days (letsencrypt.org)

Let’s Encrypt will be reducing the validity period of the certificates we issue. We currently issue certificates valid for 90 days, which will be cut in half to 45 days by 2028.
This change is being made along with the rest of the industry, as required by the CA/Browser Forum Baseline Requirements, which set the technical requirements that we must follow. All publicly-trusted Certificate Authorities like Let’s Encrypt will be making similar changes. Reducing how long certificates are valid for helps improve the security of the internet, by limiting the scope of compromise, and making certificate revocation technologies more efficient.

It's pretty simple to set up. Generate CA, keep key and other private stuff stored securely, distribute public part of CA to whoever you want and sign all the things you wish with your very own CA. There's loads of howtos and tools around to accomplish that. The tricky part is that manual work is needed to add that CA to every device you want to trust your certificates.
