Can I use one licence on two computers? — the device limit for each product, and what actually counts as a breach

Often yes — but the number is set by the vendor, not by you, and it changes from product to product. Adobe Creative Cloud on an individual plan is the clearest case: you may install the apps on two computers and use them on one at a time. Bitdefender Total Security is sold as five devices from the start, so two is comfortably inside the licence. Microsoft 365 is built for a household signed in on several devices at once. Apple Music, Google AI Pro and CapCut Pro are not counted in computers at all; they follow an account, and the limit is how many places that one account can be signed in and active at the same moment.

One rule holds across all of them: a licence is one person's seat. Two machines that belong to you, used by you, are usually fine. Two people working at the same instant on one licence are not, whatever the install count says.

Below: the actual numbers, how the counting works on the vendor's side, and the specific things that turn an ordinary setup into a breach of the terms.

Adobe Creative Cloud, individual plan: two activations, one in use at a time. Sign in on a third computer and Adobe offers to sign you out of one of the other two. The apps stay installed; only the licence moves. Here that plan is 400 MAD for four months, which is 400 ÷ 4 = 100 MAD a month.

Bitdefender Total Security: 399 MAD for one year across five devices, in any mix of Windows, macOS, Android and iOS. That is 399 ÷ 5, under 80 MAD per device for the year, and it is the one product here where two computers is not even a question.

Microsoft 365: the consumer plans are built for a household — installation on more machines than most people own, with a cap on how many can be signed in at the same time. The business plans are counted per user instead. Which plan you take changes the answer, so ask before you pay.

Apple Music, individual: sign in on a phone, a laptop and a Mac if you like, but only one stream plays at a time. The family plan is what allows several at once.

Google AI Pro and CapCut Pro publish no two-computer rule; they follow the account. Sign in wherever you work — the problem starts when one account serves more than one person.

Nothing about a licence lives on your hard drive in a way you control. When you sign in, the app asks the vendor's server whether this seat has room, and the server keeps the list: which machines, which hardware fingerprint, when each one last checked in. Uninstalling does not clear the entry. That is why “sign out everywhere” exists, and why a computer you sold or reformatted still holds a slot until you remove it from your account page — your Adobe account, Bitdefender Central, the devices list in your Microsoft account.

The check repeats. Desktop apps need to reach the vendor every so often — weeks, not years — to confirm the subscription is still paid. Work offline for a short trip and nothing changes; stay offline past the window and the apps step down to a limited mode until you connect again.

The pricing follows the same logic. A subscription is priced per simultaneous user, so a vendor does not much care whether the second install is your own laptop; it cares whether two people are getting one price. Two computers and one pair of hands is the shape the terms were written around.

The line most people cross without noticing is not the second computer. It is the second person.

• Sharing the sign-in with a friend, a cousin or a colleague outside your household. Consumer terms are written for one person, and this is the common breach.
• Running a personal plan on office machines used by staff. Professional use needs a business plan, bought through a registered channel.
• Handing over an account that also carries your mail, your files and your payment method — Google AI Pro sits on the same account as your Gmail and Drive.
• Assuming the second install is permanent. It follows the sign-in, so the machine you use least is the one that gets signed out at the worst moment.

Where ROSH™ Company Labs is the wrong choice. ROSH™ Company Labs is one person in Morocco, independent, tied to no vendor and an authorised reseller of nobody. It is not a formally registered company and issues no tax invoice. If you are buying for a business, if you need an admin console with seats assigned to employees, or if your accountant needs a deductible receipt, buy from a registered reseller instead. Purchases here are at your own risk, with no guarantee, refund or warranty behind them.

Count first. Write down how many machines, who uses them, and whether two of them could ever be running in the same minute. That last answer decides the rest.

• Two computers, one person, never at the same time — an individual licence is usually enough.
• Two computers used at once by two people — you need two seats, or a family plan where one exists.
• A house full of phones and laptops to protect — Bitdefender's five devices at 399 MAD for the year costs less than covering them one by one.

Then ask one question on WhatsApp: what form does the licence take — a key you redeem inside your own account, or a sign-in handed to you? It matters. A key you redeem stays yours, with the recovery address and the password in your hands. A sign-in you did not create depends on whoever holds that password. Ask who controls it, and what happens at renewal, before you pay — not after the second computer refuses to sign in.
