Consumer technology, like everything in life, isn’t without its caveats. In the case of iTunes, these limitations restrict the number of computers you can authorize to five, meaning you can only play content on a total of five different computers at any one time. Authorization is vital, however, given it provides Mac and PC users permission to access any audiobooks, apps, books, movies, music, and other content tied to a specified Apple ID. Without proper authorization, you’ll likely be left banging your head on the keyboard as you wonder how you can access the digital copy of The Force Awakens you purchased on your iPhone SE.

Thankfully, authorizing a computer in iTunes is quick and painless. You can carry out the task in a matter of seconds, though you’ll have to do so from the computer you wish to authorize — your iPhone, iPad, or iPod touch simply won’t cut it.
A paltry five authorizations is all you get. If you’re unsure of how many computers you’ve authorized in the past, however, Apple provides an easy to find out. You won’t be able to see the respective names of the computers — only a number — nor will you be able to view the number if you haven’t authorized two or more computers. Also, keep in mind that iOS devices, such as the iPhone and iPad, don’t count toward your available authorizations. Apple gives you some leeway in that respect.
Step 1 — Launch iTunes as you would normally and click your account name or the Sign In option in the upper-right corner. If you select the latter, enter your Apple ID and password.
Step 2 — Select Account Info from the resulting drop-down menu and enter your password again.
Step 3 — Once entered, you should be able to view the number of computers that you’ve authorized near the top of the resulting pate, within the Apple ID Summary section. This also where you can simultaneously deauthorize all your computers, in case you no longer have access to a computer that used one of your previous authorizations. To do so, just click Deauthorize All in the bottom-right corner.
