What is ACME?

ACME or Automated Certificate Management Environment is an open protocol that allows servers to request and manage SSL/TLS certificates directly from a Certificate Authority. This includes validation, issuance, renewal and revocation sans any human involvement.

With ACME, your server handles the certificate process directly — no need to generate CSRs, upload validation files, or keep tabs on expiry dates. It communicates to the Certificate Authority over HTTPS using signed JSON requests. To prove domain control, the server responds to a challenge, usually via HTTP or DNS. Once that checks out, the certificate is issued and ready to go.

Today, ACME is recognized as an official internet standard under RFC 8555 and is backed by major Certificate Authorities, including Sectigo. Its latest version, ACME v2, introduced support for wildcard domains, improved domain validation, and stronger security checks. That makes ACME SSL certificates a smart choice for teams running uptime-critical apps, managing multiple servers, or automating deployments at scale.

Why It Matters:

IETF-standard protocol trusted across the internet
Secure domain validation using HTTP/DNS challenges
Fully automated issuance & renewals — no human error
Works across internal and public networks
Supported by major ACME clients like Certbot, acme.sh, Win-ACME

Key Benefits of ACME Certificate Automation

Manage External Account Binding (EAB) per Deployment

In ACME protocol, EAB is a way to securely link your ACME client to the Certificate Authority – like a secure handshake that proves your client is allowed to request certificates. EAB uses a shared credential (a key ID and HMAC token) provided by the CA when setting up your ACME client. Each binding is like a separate access key that tracks and manages cert requests independently.

Automated Certificate Lifecycle

ACME takes care of certificate issuance, validation, and renewal automatically. No spreadsheets, no calendar reminders, and no downtime caused by expired SSLs.

Instant SSL Provisioning

Certificates are issued within minutes using HTTP-01 or DNS-01 domain validation. No manual file uploads, email approvals, or waiting on CAs.

ACME Advantages That Scale With Your Infrastructure

Running a single server or managing a distributed environment? ACME streamlines SSL certificate management at every level.

Unlimited Server Installations

Use the same certificate across multiple servers without any restrictions. ACME makes it easy to keep them all secure and up to date.

Per Domain Billing

Pay only for the domains you secure. New domains are charged based on remaining subscription days, ensuring cost-effective scalability.

Backed by Trusted CAs

Get ACME Automation SSL Certificates from top Certificate Authorities like Sectigo at SSL2BUY – trusted across all major browsers and platforms.

Built for DevOps & CI/CD Workflows

ACME fits right into your deployment pipelines, making it ideal for fast-moving DevOps teams that don’t have time for manual certificate renewals.

Massive Coverage, Fully Automated

Protect up to 499 domains and 500 wildcard entries – each one securing unlimited subdomains. ACME handles the certificate issuance and renewal automatically, so you don’t have to repeat the same steps across dozens of setups. Whether it’s a few servers or a global network, you stay secure with minimal effort.

How ACME
Works to
Automate SSL
Management

Client Setup on
Your Server

Install an ACME-compatible client like Certbot, acme.sh, or Win-ACME. This software handles the communication with the CA.

Account Registration
& Key Exchange

The client registers your server with the CA and securely exchanges keys. EAB credentials are used to authenticate if required.

Domain Ownership
Validation

The CA challenges your server to prove domain control — typically via HTTP-01 or DNS-01. The ACME client automates this step.

Certificate
Issuance

Once the challenge is successfully completed, CA issues your SSL/TLS certificate. This happens automatically and within minutes.

Certificate
Installation

The ACME client installs the certificate and configures it for your server stack – whether it’s Apache, NGINX, IIS, or containers.

Auto-Renewal
Before Expiry

Before expiration, the ACME client initiates domain control process again and fetches a renewed certificate without downtime.

Supported Server Environments

ACME works across a wide range of server setups from traditional web servers, control panels, and container platforms. If your system supports HTTPS, ACME can likely be integrated to handle certificate management automatically.

ACME SSL (Automated) vs Traditional SSL (Manual)

	ACME SSL (Automated)	Traditional SSL (Manual)
Issuance	Auto-validated via client, no manual CSR or file uploads	CSR, domain validation, and approval handled manually
Installation	Installed automatically by the ACME client	Must be manually installed on each server
Renewal	Auto-renews before expiry with no action needed	Requires manual validation and reinstallation
Scalability	Easily automates multiple domains or subdomains	Managing more domains increases workload linearly
Downtime Risk	Very low – renewals happen before expiration	High – missed deadlines can cause site warnings
Short Lifespan Ready	Even 90-day or 47-day certificates renew without disruption	Shorter terms mean more manual maintenance
Admin Workload	Minimal – Once configured, the process runs with little to no human involvement	High – Requires scheduling, tracking expirations, and frequent technical intervention
Ideal For	DevOps teams, hosting providers, SaaS platforms, or any automation-first teams	Small setups or where automation isn’t supported

ACME Certificate – Frequently Asked Questions

What does ACME stand for?

ACME stands for Automated Certificate Management Environment. It’s a protocol that helps your server get, install, and renew SSL certificates on its own, without any manual steps.

Do I need to configure ACME manually every time I add a new domain?

Not completely. Most ACME clients let you update your existing setup to include new domains without starting over. You may need to adjust your configuration or run the client again with the new domain listed, but the core setup including your ACME account and validation method stays the same.

Will I be charged a full year when I add a new domain to my certificate?

When you add a domain to an existing ACME certificate, the cost is rated based on how many days are left in your current subscription. This means you only pay for the remaining term, not a full year, making it easier and more affordable to expand your coverage anytime.

Can ACME be used for certificates behind firewalls or on internal networks?

Yes with DNS-01 validation, ACME works even if the endpoint isn’t publicly reachable. It’s ideal for securing internal applications, staging servers, or intranet sites.

What’s the difference between ACME v1 and v2?

ACME v2 supports wildcard certificates and offers better security and extensibility. v1 is deprecated and no longer supported by major CAs. All modern ACME clients and CA integrations (like Sectigo’s) use v2 by default.

Is External Account Binding (EAB) always required?

Yes, for commercial CAs like Sectigo, EAB is required. It helps securely bind your account with the CA using a pre-issued key pair. Your EAB credentials are provided through SSL2BUY’s dashboard or during onboarding.

What if my ACME client or script gets deleted? Will I lose access to the certificate?

No, the certificate remains valid until its expiration. However, for auto-renewal to continue, you’ll need to restore the client’s configuration especially the private key and account registration data. Always back up your .acme.sh, .config, or equivalent directories.

How long are ACME certificates valid, and can I control the validity period?

Validity depends on the CA. Sectigo’s ACME DV SSL, for example, can have 90-day validity (default for automation). Longer terms may be possible depending on your CA agreement and client settings. These rules are changing and certificate lifespans will be limited to just 200 days starting in 2026 and even shorter after that.
