To sign in to HP Instant Ink, you need to go to the official Instant Ink sign-in page, which is hosted at **ast.instantink.com**. This page requires you to either sign in or sign up before continuing, allowing access based on your role (e.g., Agent Support Tool user, HP employee, or regular HP.com user)[4].
If you have an HP Instant Ink account, simply enter your credentials on this page to manage your subscription, check your ink usage, or update your plan. If you’re new to HP Instant Ink, you can sign up from the same site or the main HP Instant Ink page.
For more general information about HP Instant Ink, including plans and how it works, visit the official HP Instant Ink site at **hp.com/printers/instant-ink.html**, where you can also sign up directly for the subscription service[2].
If you want to log out or manage your account after signing in, there are options within your account dashboard to sign out or cancel your subscription, as shown in tutorials such as the one detailing cancelation steps on YouTube[1].
