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.

Lol, never had to buy a cert huh?

You're still buying a year or more at a time, no matter the lifetime of the cert itself. Even if the cert lifetime was a week, you're still buying the same product, no matter how many times you rotate it.

    Personally? No I've never bought a cert before. Given there's free alternatives and it's a homelab it doesn't make sense. Otherwise I've used them on AWS, where ACM also just provides them for free.

    What you're saying is that certificate providers will still charge you and provide certificates for a year, but just provide you with N certificates to span that year?

    E.g. if the duration is 45 days then they will give you 365/45 certificates ?

    Minimum. We get through digicert at work, and we abuse the hell out of our wildcard and reissue it tons of times a year. You're buying a service for the year, not an individual cert.
