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.



WTF? I’m not trying to tell you how to do anything. I’m sick of selfhosted twerps bitching about “how hard it is to self host” when they think everything should be like an app on their phone. You need to learn how networks, dhcp, dns, ssl, certificates, etc. work.
guess what, I know how these work. running 2 dozens of services over two machines, and as I said above, I use my own root certificate… that’s how I know that lots of apps have problems of varying severity with custom root certs! usage of user-installed certs is opt-in nowadays for smartphone apps, it’s not at all like on windows or linux.
you are telling how to do things. the whole thread has been about you telling us to rent a domain for certificates and stop complaining about it being the only viable way…
